Functional Devices does it again! The RIBMNLB-1 gives you a simple and effective FAN SAFETY ALARM CIRCUIT control.
Alarm Fault Application: When the Latch/Fault Input is Closed (Normal state), the Relay is activated, and Red LED is Off. When Latch/Fault Input Opens (Alarm state), the Relay deactivates, and Red LED turns On. Until the Latch/ Fault Input is Closed AND either power is cycled or the RESET button is pressed, relay will remain in the Alarm state.
Notes:
• Fault conditions must last for at least 500 ms in order for the unit to go into Alarm state.
• Reset signal, whether via pushbutton or power cycling, must last for at least 30 ms in order to reset the device to go from Alarm state to Normal state.
