FAIL/Status Output Relay (/F1)
Item Specifications
FAIL output Relay contact output on CPU error
Relay operation Energized during normal operation and de-energized on system error.
Status output Output a relay contact signal when a selected condition occurs.
A combination of the following conditions can be selected:
Low memory, memory failure, media error, A/D hardware error, burnout detection, communication
error (Modbus master or client communication error), memory sampling stop.
Relay operation Relay is energized when a condition occurs.
Relay contact rating 250 VAC (50/60 Hz)/3 A, 250 VDC/0.1 A (for resistance load)
