GE Fanuc UR8FH – Universal Relay Module with 8 Poles, Fast Response, High Current

In stock

Product Introduction:
The UR8FH is a high-speed, high-density universal relay module for GE Fanuc PLC systems. The “UR” stands for Universal Relay, “8” indicates eight relay poles per module, “F” denotes Fast response time, and “H” indicates High Current. This module is designed for applications where relay speed is critical, such as safety interlocks, sequential control, and high-speed sorting systems. The fast response time (5ms energize, 2ms de-energize) is achieved through optimized coil design and low-mass armatures. The high current rating of 10 Amps per pole ensures it can switch demanding loads even at high speed. Eight poles in a single 3U module provides exceptional density.

Technical Specifications:

Functional Features:
Ultra-Fast Response: 5ms energize and 2ms de-energize, twice as fast as standard relay modules.
Eight Poles Per Module: Highest density in the UR family, reducing rack space by 40 percent compared to standard modules.
Common Return Wiring: Shared return terminal simplifies wiring for large banks of relays.
High Current at Speed: Maintains 10 Amp rating even at fast cycling rates, unlike standard relays that derate at high speed.
Low-Mass Armature: Optimized mechanical design reduces contact bounce and extends life at high cycle rates.
Snubber Protection: RC snubbers on every contact suppress the higher arcing energy generated by fast switching.

Application Scenarios:
Safety Interlocks: Fast de-energization ensures emergency stop relays drop out in 2ms, protecting personnel and equipment.
High-Speed Sorting: Controls eight diverter arms in a packaging or postal sorting system operating at high speed.
Sequential Control: Executes fast sequential steps in batch processing where timing is critical.
Pulse Counting: Used in applications where relays must switch on and off rapidly for pulse generation.
Alarm Systems: Drives eight alarm outputs that must activate simultaneously within milliseconds.
