20. Current Loop Output (OP-08)

Replacing the RS-232C interface with this option, current loop output, 3-relay outputs and 1-control input can be used with the RS-232C interface of this option.

RS-232C functions and pin connections are the same as the RS-232C interface described in “16. RS-232C Interface”.

The control input can control the indicator from an external terminal just like the front panel key operations.

Set the external control function at f15 of the F-Functions.

When connecting the function pin and the common pin, the indicator makes the action. Keep a signal width of more than 100 ms for the On-time and Off-time.

ON(Make)
More than 100 ms	More than 100 ms
OFF(Break)
