Allen Bradley 1771-P4R Power/Relay Contact Output Module
1771-P4R is a PLC-5 series 120VAC redundant power supply+8-point relay output composite module, which not only supplies power to the 1771 backplane, but also has dry contact output. It is a commonly used spare part for maintenance of old systems.
1. Module type: 1771 rack redundant power supply+8-way relay contact output 2-in-1
2. Input voltage: 97-132VAC (rated 120VAC), 47-73Гц
3. Backplane output: 5VDC/8A, providing power to CPU and I/O modules
4. Relay output: 8 points (4 groups x 2 points), normally open dry contacts
5. Contact capacity: 24VAC/DC maximum 100mA/point, resistive load
6. Isolation and voltage resistance: 1000VAC between contacts, 1500VAC between coil and contacts
7. Redundancy feature: Dual module parallel connection, automatic fault switching, uninterrupted power supply
8. Self contained fuse: Built in 1.5A/250VAC slow melting fuse
9. Alarm output: 250VAC contact alarm, external indication for abnormal power supply
10. Backplane current: 420mA, single slot installation, compatible with 1771-A1B~A4B rack
11. Status indication: power/running/fault LED, output channel status visualization
12. Wide temperature operation: 0-60 ℃, storage -40~+85 ℃, suitable for industrial sites
13. Humidity range: 5-95% RH (non condensing), resistant to harsh environments
14. Plug and unplug design: modular structure, easy disassembly and maintenance
15. Usage: Power supply for old systems+low voltage load control (indicator lights, small relays, solenoid valves)
