External Connection Diagram
TC : Input terminal for thermocouple
RTD : Input terminal for the resistance temperature detector
DC : Input terminal for DC current or DC voltage.
For DC current input, connect a separately sold reception resistor (50Ω) between the input terminals.
OUT1 : Output terminal for the control output or heating output [optional: heating/cooling control].
POWER SUPPLY : Power supply terminal.
EV1/OUT2 : Output terminal for alarm output 1 or cooling output [optional: heating/cooling control].
EV2 : Output terminal for alarm output 2.
D1 : Input terminal for DI input (There are three types of DI input, SV1 / SV2 external switching function, OUT / OFF (RUN / STOP) external switching function, and timer function)
RS-485 : Communication terminal for serial communication.

COMMUNICATION FUNCTION CONNECTION DIAGRAM (PLC Connection Diagram)
Note: Terminating resistors (Terminators)
The KT series has a built-in pull-up resistor or pull-down resistor, which serves as the terminating resistor.
For this reason, do not connect the terminating resistor on the communication line.
