📋 Key Technical Specifications

🧩 Features

1. Relay dry contact isolation: Galvanic isolation between PLC low-voltage side and load high-voltage side. Suitable for solenoid valves, контакторы, indicator lamps and other AC loads.
2. Substitute value: When communication fails or CPU stops, output state can be preset in TIA Portal: hold / reset to 0 / set to 1.
3. Channel status LEDs + module diagnostic LED for fault alarm.
4. Separate base & electronic module design: Hot-swappable electronics while wiring remains on base for easy maintenance.

⚙️ Typical Application Scenarios

Control of 220VAC solenoid valves, small contactors, alarm lamps, fan start/stop in control cabinets

Not suitable for high-frequency switching applications (limited relay mechanical service life; cannot handle high-speed pulses)

Distributed remote IO station deployed with IM155-6 interface module

⚠️ Выбор & Примечания по проводке

1. Base unit must be BU B0 / BU B1 type, A-type bases are incompatible; recommended BU20-P16+A0+2B.
2. Relay contacts are passive dry contacts. Load power is not supplied by module backplane, external power supply required.
3. Индуктивные нагрузки (катушки контактора) are recommended to connect varistor / freewheeling diode in parallel to extend relay service life.
4. 5A per channel is rated current; pay attention to heat dissipation when all 4 channels run at full load simultaneously.

Field instrument power switching, warning lights, on-site audible & визуальные сигналы тревоги

Water tank level interlock output; remote stations deployed at different plant locations

Преимущество: Relay isolation prevents field high-voltage interference from coupling into PROFINET bus

1. Supported Load Types
2. AC220V solenoid valves, индикаторные лампы, buzzers
3. AC220V contactor / intermediate relay coils
4. Резистивные нагрузки: heating tapes, лампы накаливания (≤5А)
5. DC24V~DC120V DC loads (dry contacts work for both AC and DC)
6. Passive contact output for hard-wired interlock with other control systems

III. Неподходящие приложения

1. ❌ High-frequency switching: Mechanical relay has limited service life, not for multiple operations per second. Use transistor DQ modules for high frequency.
2. ❌ Direct drive of high-power motors (only drives contactor coils, not main motor circuit)
3. ❌ Inductive load current exceeding 2A (solenoid & contactor are inductive loads; varistor / freewheeling diode required to absorb back EMF)
4. ❌ Safety circuits (this module is non-failsafe. F-RQ failsafe modules are required for emergency stop and safety gate circuits)
5. ❌ High inrush current loads (contact erosion risk; each channel needs external 6A max. fast fuse protection)
6. Architecture Characteristics

ET200SP distributed IO: This module is mounted in remote field enclosures away from the main PLC and connected via IM155-6 PROFINET interface module.

Load wiring for 220VAC is routed locally, reducing long-distance high-voltage cables

Relay isolation protects PLC low-voltage system and improves EMC immunity

Substitute value configurable in TIA Portal: Output state can be defined for bus interruption or CPU stop to ensure safe equipment status

ET200SP Digital Output Module Selection Comparison Sheet

Compare 6ES7132-6HD01-0BB1 (RQ 4-channel relay output) vs common transistor DQ modules

1. Таблица сравнения основных параметров

1. When to select 【6ES7132-6HD01-0BB1 Relay Module】

✅ Рекомендуется

1. Load voltage is AC220V, no extra intermediate relay required on site
2. Galvanic isolation required, heavy field interference, prevent high voltage from damaging PLC IO bus
3. Need passive dry contact output for hard-wired interlock to 3rd-party DCS / реле защиты
4. Low switching frequency (triggered every few minutes/hours, not frequent on/off)
5. Mixed loads: both AC220V and DC loads up to 120V

❌ Not Recommended

1. Frequent switching: multiple start-stop per second (rapid contact wear and shortened lifetime)
2. Pure DC24V loads with large point count requirement (transistor modules cheaper, higher channel density)
3. High-speed pulse & motion control output (relay cannot generate pulses)
4. SIL safety circuits (Failsafe F-series modules required)

III. When to select 【Transistor DQ Module】

✅ Рекомендуется

1. All loads are DC24V, frequent switching (continuous actuation of cylinder solenoids)
2. Requirement for high-speed switching signals or pulse outputs
3. Large I/O point count, high channel density to save cabinet space
4. Field loads are low-current DC components without isolation requirement

❌ Not Recommended

1. AC220V loads: must add external intermediate relays
2. Severe field high-voltage interference without isolation; risk of IO module burnout
3. Quick Selection Rule

Нагрузка: 220 В переменного тока, low frequency, isolation required → 6ES7132-6HD01-0BB1

Нагрузка: 24 В постоянного тока, frequent operation → Transistor DQ (6BH01 for many points / 6BD20 for high per-channel current)

1. Additional Selection Notes
2. Индуктивные нагрузки (электромагнитные клапаны, контакторы) need absorption components: varistor in parallel for AC loads, freewheeling diode for DC loads to suppress back EMF and extend contact life.
3. Relay module base color code CC40, not interchangeable with transistor DQ base CC01.
4. Cost reference: Relay modules usually cost more for same channel quantity. Однако, overall system cost may be lower when eliminating external intermediate relays.
5. Failure characteristics: Relay contacts risk sticking; transistor modules mostly fail by breakdown with no mechanical sticking risk.
6. Special Alternatives

Failsafe output: 6ES7136-6DB00-0CA0 (F-DQ for safety circuits)
