*Without latching hold function, the unit is tripped upon starting operation when

the unit is set to Low alarm.

With the function, the unit is NOT tripped until the temperature goes once above

and then below the setpoint.

DISPLAY

Display: 4 digits of 10 mm (.39”) height, 7-segment LED

Scaling range: -1999 to 9999 counts

Measured Value (PV)/Alarm (SET1) display: Red LEDs

Alarm (SET2) parameter display: Green LEDs

PV display at abnormal input: Over range or under range

displayed

Front LEDs

Power indicator: Green LED turns on while the power is

turned on.

Measured Value (PV) indicator: Green LED turns on when PV

display is set.

Alarm SET1 indicator: Red LED turns on when the Alarm

SET1 is in tripped conditions.

Alarm SET2 Indicator: Red LED turns on when the Alarm

SET2 is in tripped conditions.

INPUT SPECIFICATIONS

■ DC Voltage: -5 – +105 %

Input resistance: ≥ 1 MΩ

OUTPUT SPECIFICATIONS

■ Relay Contact: SPDT relays

220 V AC @3 A (cos ø = 1)

30 V DC @3 A (resistive load)

Caution: N.O. and N.C. contacts could be conductive at the

same time. DO NOT connect both contacts at the same
