MAIN OUTPUT

: Control output

EVENT OUTPUT : Outputs when Alarm, Loop break alarm or Heater burnout alarm (option) is ON.

RS-485

: Serial communication

TC :

Thermocouple

RTD

: Resistance temperature detector

DC

: DC current (DC mA) or DC voltage (DC V)

Shunt resistor

: Shunt resistor 50

Ω for input signal DC current

• Option: Heater burnout Alarm

(1) This alarm is not available for detecting current

under phase control.

(2) Use the current transformer (CT) provided, and pass a

lead wire of the heater circuit into a hole of the CT.

(3)When wiring, keep the CT wire away from any AC source

or load wires to avoid the external interference.
