Full Application Scenarios of PSR-SPP-24DC/ESD/4X1/30 (Item No.2981813)

Core advantages of this model: 2-channel safety monitoring + 2 instantaneous safety contacts + 2 dropout delay contacts (0.1~ 30 ثانية) + Cat.4/PL e/SIL3. It is specially designed for safety conditions where equipment carries large rotational inertia and cannot be fully powered off instantly. All scenarios support monitoring of three categories of safety components: E-stop buttons, safety door interlocks and safety light curtains.

1. Basic Safety Signal Monitoring (Universal for All Automated Equipment)

1.1 Dual-channel Emergency Stop Circuit Monitoring

Dual-channel E-stop detection for machine tools, standalone production line units, robots and packaging machinery

Supports manually monitored reset / automatic reset, with detection of short-circuits and open-circuit faults in E-stop wiring

Instantaneous contacts cut off main drives immediately; delayed contacts control slow stop of auxiliary loads including fans, conveyors and lubrication systems

1.2 Equipment Safety Guard Door Monitoring

Dual-channel monitoring of safety door interlocks for stamping machines, injection molders, مراكز التصنيع, robot enclosures and automated modules

Main spindle/servo power is instantly cut off when the door opens; cooling, chip removal and conveyor systems keep running with delay until full inertia stop before disconnection

Detects cross-wire short-circuits in door switch wiring, fully compliant with machinery safety standards

1.3 Safety Light Curtain Signal Evaluation

Safety circuits for light curtains on stamping, الانحناء, robotic loading/unloading and packaging lines

Main motor cuts off instantly upon curtain obstruction; delayed contacts operate discharge roller conveyors to clear residual materials

Built-in cross-circuit fault diagnosis, meeting the highest PL e safety rating requirements

2. Core Featured Scenarios (Relying on ESD Dropout Delay Function, Exclusive Strength of This Model)

2.1 نقل & Logistics Equipment (Belt Conveyors, Roller Lines, Stacker Cranes)

سيور ناقلة, خطوط فرز الأسطوانة, automated warehouse roller conveyors, packaging transport lines

Operating logic: After E-stop or door opening, main drive cuts off instantly; rollers remain running for an adjustable delay of 0.5~10s to clear materials on belts, avoiding material extrusion, machine jamming and belt tearing

Widely applied in food packaging, warehousing logistics and lithium battery assembly lines

2.2 Rotational Inertia Load Equipment (المشجعين, Centrifugal Machines, خلاطات, Extruder Screws)

Injection extruders, pelletizing screws, high-speed agitators, centrifugal dehydrators, high-power cooling fans, ضواغط الهواء

Operating logic: Main spindles carry massive inertia; instant power-off risks screw fracture and impeller damage. Main power is cut off instantly, while lubrication and cooling fans keep operating for 3~30s until rotational speed drops to zero before auxiliary circuits are disconnected

Standard configuration for plastic extrusion, chemical mixing, lithium coating and rubber pelletizing industries

2.3 Web Winding, Slitting & Printing Equipment

Film slitters, paper printing machines, non-woven winders, lithium battery electrode slitters

After safety trigger, winding/unwinding servos cut off instantly; tension rollers keep running for 2~8s to prevent sudden web breakage and flying material hazards to operators

2.4 أدوات الآلة & Metal Processing Equipment

CNC machining centers, CNC lathes, punch presses, آلات الانحناء, المطاحن, ماكينات القطع بالليزر:

1. Instant cut-off of spindle servos when safety door opens or E-stop is activated
2. Delayed contacts continuously run cutting fluid pumps, cooling fans and chip conveyors; all power disconnected upon delay expiry
3. Prevents damage to cutting tools and spindle bearings caused by rapid shutdown of hot spindles without cooling

2.5 Robot Workcells & Automated Assembly Units

6-axis robots, gantry manipulators, loading/unloading modules, welding stations:

Robot servos cut off instantly upon trigger from enclosure safety doors or area light curtains

Delayed control for slow stop of conveyors, fixture air blow dust removal and cooling fans

Compliant with safety specifications for auto parts and 3C electronics assembly

2.6 طعام, الصيدلانية & Packaging Equipment

Filling machines, آلات الختم, horizontal form fill seal packaging machines, pharmaceutical sorting equipment:

Main transmission cuts off instantly when safety guards are opened

Discharge conveyors run delayed to clear food/medicine bottles, avoiding mold jamming and cross-contamination from accumulated materials

3. Summary of Complete Sets of Applications by Industry
4. Machine Tool Industry: CNC equipment, punch presses, آلات الانحناء, laser cutters, آلات صب الحقن
5. اللوجستية & Warehousing Industry: Belt conveying, roller sorting, automated warehouse stacker cranes
6. Rubber, بلاستيك & الصناعة الكيميائية: Extrusion pelletizing, high-speed mixing, film slitting machines
7. الروبوتات & الأتمتة: لحام, loading/unloading, enclosure safety protection for 3C assembly robots
8. Lithium New Energy Industry: Safety monitoring for electrode slitting, coating and cell assembly lines
9. طعام & صناعة الأدوية: Safety door + light curtain monitoring for filling, packaging and sorting equipment
10. General Fan & Air Compressor Station: Safety circuits for maintenance access doors of high-power fans and water chillers
11. Model Selection Guidance (Why Choose This Model Over Standard Non-Delayed Safety Relays)
12. Standard safety relays cut off all contacts simultaneously; inertia loads easily suffer equipment damage and material jamming
13. This model separates instantaneous safety circuits and delayed auxiliary circuits, balancing operator personal safety and equipment protection
14. Push-in spring cage terminals (SPP) enable tool-free wiring and higher mass assembly efficiency in control cabinets
15. Sealable delay adjustment knob prevents equipment faults caused by unauthorized on-site personnel shortening delay time
