17. 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 “13. RS-232C Interface (OP-04, OP-05, OP-08)”.

The control input can control the indicator from an external terminal just like the front

panel key operation.

Set the external control functions 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)
