5.4.2 Output Terminal Connection
(1) Connection of output signal/power supply
cable
Connect the output signal cable (shared with the
power supply cable) to the – terminal and the +
terminal. For details, refer to Figure 5.2, “Loop
construction”.
(2) Connection of wiring for field indicator
Connect the lead wire for the field indicator with
the – terminal and the C terminal.
Note: Use a field indicator with an internal resistance of 10W or less.

(3) Connection of check meter
Connect the check meter with the – terminal and
the C terminal.
The current signal of output signal 4 to 20 mA DC
is output from the – terminal and the C terminal.
Note: Use a check meter with internal resistance of 10⍀ or less.
