ＴＴＭ－３３９－□ □－□□□□□□
① ② ③
Symbol Item Description
Size 96 x 96
Input Multi-input: Thermocouple, resistance temperature detector, voltage and current
① OUT1 (Primary
control)
R Relay contact output
P SSR drive voltage output (0 to 12 VDC)
I Current 4 to 20 mADC output
② OUT2
(Primary/secondary
control)
N None
R Relay contact output
P SSR drive voltage output (0 to 12 VDC)
I Current 4 to 20 mADC output
③ Option A Relay contact outputs EV1 to EV3 *1
B Relay contact output END signal output
C Open collector outputs TS1 to 4, TIME, EV4 output *2
D CT input *3
E No-voltage contact input
M Communications RS-485
T 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.
