Power Supply and Backup Monitoring
The F7131 is identified for power supply and backup monitoring in a safety-related control context. Its listed 5 V DC and 24 V DC current requirements describe two operating supply rails; however, the supplied information does not specify whether these values represent maximum consumption, typical consumption, or separate monitored circuits.
The stated battery voltage range is 2.8-3.6 VDC. Confirm the required battery type, monitoring thresholds, and backup behavior against the applicable technical documentation before selecting or commissioning the module.
Alarm Output and Communication
The module has a 24 VDC alarm output rated at 10 mA and an RS-485 communication interface. The alarm output provides a specified electrical interface for alarm signaling, while RS-485 supports serial communication with compatible equipment. The available information does not establish the communication protocol, connector pinout, or alarm logic, so these details should be verified before wiring.
System Monitoring and Diagnostics
The F7131 monitors the 5 V system voltage generated by up to three power supply modules. Three front-panel LED indicators show power supply status, while three test bits provide diagnostic information to compatible central modules identified as F 8650 or F 8651. These signals support system-level fault indication and diagnostic processing.
For additional power supply monitoring, the module can work with the B 9361 assembly kit. In this configuration, three 24 V outputs indicate the status of power supply modules PS1 to PS3.
Buffer Battery Maintenance
The F7131 supports buffer battery functions associated with the H51q system. The specified battery type is CR-1/2 AA-CB, HIMA part number 44 0000016. Periodic battery replacement is recommended at four-year intervals to maintain the intended backup function.
Before maintenance, confirm the installed battery type and follow the applicable system procedure. After replacement, verify the module’s status indications and relevant diagnostic signals.
