17.4.8 15 V DC Loop Power Supply Wiring
17.4.9 24 V DC Loop Power Supply Wiring
IM 05P01D31-01EN
When retransmission output is not used for retransmission output, it can be used for
control output or 15 V DC loop power supply.
The current output range can be changed.

(Recorder etc.)
Receiving resistor:
Class D grounding
600 Ω or less
(grounding resistance
of 100 Ω or less)
This can be used when it is not used for retransmission output.
The controller is equipped with a non-isolated loop power supply (14.5 to 18.0 V DC) for
connecting a 2-wire transmitter.

OUT terminal and OUT2 terminal also can be used.
This can be used when the optional suffix code /LP, L1, LCH1, L4, or LC4 is specified.
The controller with the optional suffix code /LP is equipped with an isolated loop power
supply (21.6 to 28.0 V DC) for connecting a 2-wire transmitter.
