Description
- The FRRU004-MOM4 Monitored Output Module provides a programmable power source to control output devices like notification appliances and releasing devices. It continuously monitors wiring connected to terminals A+, A- for open or short circuits, along with 24+ and 24- when 24VDC is applied.Additionally, the module includes a red LED to indicate status. In normal conditions, the LED flashes. Once activated, the LED stays lit. If a problem occurs, the LED will turn off, allowing for quick troubleshooting.
