1550107

Overview

The Phoenix Contact part number 1550107 is a RIF-0-RPT-24DC/21/MS plug-in power relay module. It features a single changeover contact and operates on a 24 V DC coil voltage with a bipolar drive. The unit supports continuous duty (100% ED) and includes manual actuation capability. Electrical isolation between the coil and contact is rated at 4 kV AC. The typical switching time is 5 ms for make and 2.5 ms for break, with a mechanical life of 1x 10^7 cycles.

Feature Summary

• Plug-in design for direct mounting onto compatible base units
• Manual actuation mechanism for operational testing
• Bipolar coil drive configuration

Applications

• Industrial control cabinet signal distribution
• Automation system interface modules
• PLC output expansion circuits

Procurement Notes

Verify that the specific order matches part number 1550107 to ensure correct coil voltage and contact configuration. Confirm compatibility with the intended base socket before procurement. Check official documentation for required accessories, as this component requires separate mounting hardware for operation.

Selection Notes

Select this model when a compact, plug-in relay with manual override functionality is required. Ensure the application environment supports the specified insulation categories and pollution degree. Verify that the load current requirements fall within the relay's rated capacity for the selected contact type.

Part Context

This component belongs to the RIF series of miniature plug-in relays manufactured by Phoenix Contact. These devices are designed for DIN rail or panel mounting systems using standardized base sockets. The series provides modular solutions for isolating control signals from higher power loads in industrial automation environments.

Replacement Considerations

No public substitute part numbers are confirmed.
