<Note 1>
If inter-controller communication (master-slave operation) is used, select code: W, X, or Y (that means "with communication 2") for a master device, and 5 or X (communication 1: RS-485) for a slave device.

*1 For program or retransmission output, specify voltage or current.
For digital output, specify relay or open collector output.
*2 Heater break alarm (HBA) is not available or current/continuous voltage output.
Loop break alarm (LBA) is not available for heat/cool PID control type.
*3 Position proportional control can be used with/without FBR (feedback resistance) input.

Control output (OUT1, OUT2) assignment by control action
PID control action:
Control output is produced from OUT1. OUT2 can be used as retransmission output or digital output.
Heat/Cool PID control action:
Heating output is produced from OUT1 and cooling output from OUT2.
Position proportioning PID control action: Opening output is produced from OUT1 and closing output from OUT2.
