eTRON M100 - Electronic refrigeration controller

The JUMO eTRON M100 is an electronic refrigeration controller designed for use in cold rooms, refrigerated display cases, or refrigerated counters

The JUMO eTRON M100 is an electronic refrigeration controller designed for use in cold rooms, refrigerated display cases, or refrigerated counters, connecting to resistance thermometers Pt100, Pt1000, KTY1X-6, or KTY2X-6. It monitors the temperature of the cold room via the first measurement input. The second input monitors the temperature of the evaporator, terminating the defrosting process once the defrost limit is reached. It displays measurement values and parameters on a three-digit, backlit display.

This controller provides 3 relays for the refrigeration unit, defrost heater, and fan. Alarms can be optionally signaled through a relay or a built-in buzzer. Relay statuses are indicated by LEDs. Additional options include a data logger with adjustable recording intervals for HACCP-compliant documentation, an RS 485 interface, and a real-time clock. Electrical connections are made via screw terminals. Device operation and configuration are managed through 4 buttons. For easy configuration and data logger analysis, a setup program and PC interface are available as accessories.
