Operational Application
The 125710-01 is used to interface the 3500 monitoring system with external actuators such as alarms, sirens, or pilot relays for motor starters. It ensures machinery enters a safe state during abnormal vibration, temperature, or positional events, supporting automated protection and emergency shutdown protocols in turbines, compressors, and other critical rotating equipment.
Technical FAQ
Q: Can this module be used for motor starting?
A: The 2 A relays are intended as “pilot” relays to signal larger motor starters or PLC inputs, not to drive heavy motors directly.
Q: Where is this module installed in the rack?
A: Installs in the rear of the 3500 rack, directly behind the corresponding 3500/32 Relay Module.
