Jumo 701061 Panel Mount Controller, 36 x 76mm 3 Input, 3 Output Relay, 12 → 24 V ac/dc Supply Voltage Controller

The Jumo Electronic Cooling Controller for panel mounting (76 x 36 mm) has 2 measuring inputs and 3 relays. The voltage supply is AC/DC 12 to 24 V +15/-15 %, 48..63 Hz. The electronic cooling controller for use in cold-storage rooms, display refrigerators, or refrigerating counters to be connected to RTD temperature probes Pt100, Pt1000, KTY1X-6 or KTY2X-6.The first measurement input is used to acquire the temperature of the cold store. The second measurement input acquires the evaporator temperature, and ends the defrosting process as soon as the limit for defrosting has been reached. The measurements and parameters are shown in a 3-character backlit display. Further options include a data logger with an adjustable recording interval for HACCP-compliant documentation1, an RS485 interface, and a real-time clock. The electrical connection is made via screw terminals. Four keys serve for instrument operation and parameterization.

Three relays available for cooling unit defrosting heating and fan
Alarms optionally generated via relay or integrated buzzer
Switching states indicated via LEDs
