Mounting: DIN rail mounting
External dimensions: 22.5 (W) x 75 (H) x 100 (D)mm

Attached functions
Power failure countermeasure:The data is backed up in non-volatile IC memory.
Self diagnosis:
The CPU is monitored by a watchdog timer, and whenan abnormal status is found on the CPU, the unit isswitched to warm-up status after turning all outputs off.
Detecting unconnected sensor:
If pulse is not detected for a constant period (1sec), the unit
will revert to the initial status (0Hz).
