Description

Size

96 x 96

Input

Multi-input: Thermocouple, resistance temperature detector, voltage and current

①

OUT1 (Primary

control)

Relay contact output

SSR drive voltage output (0 to 12 VDC)

Current 4 to 20 mADC output

②

OUT2

(Primary/secondary

control)

None

Relay contact output

SSR drive voltage output (0 to 12 VDC)

Current 4 to 20 mADC output

③

Option

Relay contact outputs EV1 to EV3 *1

Relay contact output END signal output

Open collector outputs TS1 to 4, TIME, EV4 output *2

CT input *3

No-voltage contact input

Communications RS-485

English version panel sheet

*1 No EV3 if a relay contact output is selected for OUT1. No EV2 if a relay contact output is selected for OUT2.

*2 No EV4 if a relay contact output is selected for OUT1 or OUT2.

*3 Select I for OUT1 or OUT2. This CT is of a type to limit the operation amount but not to detect disconnection. It is

effective for the PID control of the heat control.
