2. Especificações elétricas principais

3. Matching Terminal Units (Mandatory for Use)

The module cannot be wired independently and requires selection of the following TU terminal bases:

TU810 / TU812 / TU814 / TU830 / TU833

Supports hot swapping; online module replacement without system shutdown

4. Hardware Structure & Recursos funcionais
5. Dual Isolated Group Design

O 16 channels are split into Group 1 (Channels 1–8) and Group 2 (Channels 9–16). The two groups feature independent isolated power supplies; a short circuit in one group will not disrupt outputs of the other group.

2. Independent Channel-level Protection

Each channel is equipped with current limiting and over-temperature shutdown functions. The faulty channel cuts off automatically upon short circuit while all other channels remain operational with fault feedback signals.

3. Loop Voltage Monitoring

Power supply detection inputs are configured for each group. The controller receives fault alarms in case of on-site 24V power loss to prevent misoperation.

4. Industrial EMC Anti-interference Performance

Built-in filters and surge absorbers for deployment in high electromagnetic interference sites such as chemical plants, power plants and metallurgical facilities.

5. Hot Swap Compatibility

The S800 I/O bus supports live insertion/removal, enabling maintenance without system shutdown.

Full Practical Application Cases of ABB DO810 (3BSE008510R1)

Module Positioning: S800 I/O 16-channel 24VDC sourcing digital output module paired with AC800M / 800xA DCS. It drives solenoid valves, small relays, on-site indicator lights, fan and pump start/stop contacts, with built-in group isolation, short-circuit diagnosis and hot-swap functions, ideal for mass discrete point control in process industries.

Caso 1: Auxiliary Control System for Thermal Power Boilers (300MW Domestic Thermal Power Plant)

Visão geral do projeto

The unit is equipped with three sets of auxiliary control DCS for coal conveying, ash removal and chemical water treatment. The complete system adopts ABB 800xA + AC800M Controllers, with remote S800 I/O stations deployed in coal bunker rooms, electrostatic precipitator workshops and chemical water treatment buildings. DO810 (3BSE008510R1) modules are used in bulk quantities.

Application Points of DO810

1. Coal conveyor interlock: Conveyor start/stop solenoid valves, deviation/pull-cord alarm indicator lights, limit solenoid valves for tripper cars
2. Electrostatic precipitator system: Anode & cathode rapping coils, ash hopper unloading solenoid valves, high/low level indicator lights
3. Boiler chemical dosing & water purification: Sampling valves, flushing solenoid valves, coils of chemical dosing pump control relays

Realized Selection Advantages

1. High integration with 16 canais; one single module covers 8 dual isolated loop groups to reduce the number of I/O stations and save cabinet space
2. Independent isolated power supply per group; short circuit of a single solenoid valve only locks the 8 channels within the corresponding group without triggering full coal conveyor interlock shutdown
3. Channel short-circuit and 24V loop power loss signals are transmitted to the 800xA monitoring screen in real time for fast fault location by operators
4. Hot swap support enables replacement of faulty modules without unit shutdown, avoiding load derating

Configuration Quantity

6～12 pieces of DO810 equipped with TU810 terminal bases per auxiliary control station, driving 24V on-site solenoid valves and indicator lights with load ≤0.5A.

Caso 2: DCS Project for 1 Million Ton/Year Coking & Coal Chemical Plant (Plateau Coal Chemical Plant in Qinghai)

Histórico do projeto

Distributed control system built with AC800F + S800 I/O for coking byproduct recovery, desulfurization, ammonia distillation and crude benzene rectification units. DO810 modules are extensively installed in on-site explosion-proof cabinets.

Control Scenarios

1. Process pneumatic shut-off valves and regulating valve solenoids
2. High/low level interlock vent valves and reflux valves for towers
3. On-site explosion-proof audible & visual alarm lights, local control column indicator lights
4. Drive of intermediate relays for circulating water pump and fan control loops

Solutions to On-site Pain Points

Coal chemical sites feature heavy dust, numerous inverters and strong electromagnetic interference:

Optocoupler isolation between groups plus built-in surge absorbers eliminate valve misoperation caused by inverter interference; independent channel current limiting prevents module backplane burnout in case of short circuits from medium leakage.

Project Highlight

The module’s wide operating and storage temperature range fits the plateau low-temperature environment (minimum -15℃ in winter) without additional heating devices.

Caso 3: Large Municipal Sewage Treatment Plant (50,000 m³/d Municipal Sewage Plant)

Control Scope

Full-process automatic control of coarse screens, fine screens, tanques de aeração, sedimentation tanks, sludge dewatering workshops and chemical dosing rooms.

Load List of DO810

1. Screen washing solenoid valves, scraper direction switching valves
2. Start/stop relays for PAC/PAM chemical dosing metering pumps
3. Solenoid valves for electric butterfly valves on aeration air ducts
4. Indicator lights for liquid level and dissolved oxygen over-limit alarms, local running indicator lights

Application Values

1. Dense measuring points in chemical dosing rooms; one DO810 module covers 16 dosing valves to drastically cut wiring workload
2. 24-hour continuous sewage treatment operation with channel-level fault diagnosis, eliminating manual line-by-line inspection
3. Remote I/O cabinets installed adjacent to aeration tanks to shorten cable routing lengths from the central control room

Caso 4: Automated Automotive Component Assembly Production Line (Intelligent Manufacturing Line)

Line Requirements

Engine valve assembly line including loading, clamping, inspection and unloading stations. Local AC800M PLC controls cylinders, indicator lights and sorting solenoid valves.

Application Methods of DO810

1. Drive production line cylinder solenoid valves (24CCV, single coil current 0.3～0.4A, matching the 0.5A channel capacity)
2. Three-color OK/NG status indicator lights at stations, emergency stop reset indicator lights
3. Sorting diverter valves, silo replenishment solenoid valves

Advantages vs Traditional Schemes

The original design adopted 8-channel DO modules requiring 3 pieces per line. Switching to DO810 covers 16 channels with one module, halving the number of cabinet I/O modules, reducing cabinet volume by 30% and shortening commissioning hours.

Caso 5: Tank Farm Interlock Control System for Refinery (800,000 Ton Product Oil Tank Farm)

Control Points

Tank farm emergency shut-off valves, nitrogen sealing valves, high-level interlock vent valves, on-site explosion-proof indicator lights, fire sprinkler solenoid valves

Utilized Safety Features

1. Group isolation design of the module separates feed valves and vent valves into different channel groups; single loop faults will not trigger false full-tank interlock actions
2. Real-time 24V output power monitoring; SIS alarms triggered immediately upon cable breakage or power loss
3. Compliant with IP20 installation standards for refinery explosion-proof cabinets and usable with intrinsic safety isolation terminals

Caso 6: Circulating Turbid Water Treatment Station for Steel Plants (Circulating Water Supporting Rolling Mills)

Controlled Equipment

Cooling tower fan start/stop, filter backwashing solenoid valves, blowdown valves, water quality dosing valves, local running indicator lights

On-site Adaptation Advantages

Rolling mill workshops have high water vapor and slight condensation. DO810’s wide-temperature and moisture-proof circuit design ensures long-term stable operation. Multiple channels centrally control multiple groups of filter backwashing valves to simplify interlock logic programming.
