Keeping Your Temperature Measurement on Track with JUMO Electronic Thermostats

The electronic thermostat for DIN-rail mounting, JUMO eTRON T100, was especially designed for temperature control and monitoring. As an option to the thermostatic function, it can also be used for more demanding control processes and delivers a significantly higher control quality in the version as a PID two-point controller with self-optimization.

The JUMO eTRON T100 sets itself apart with its compact size and large functional range, including – among other things – an integrated timer, data logger, service and operating hours counter, PhotoMOS output for additional limit value signaling, and digital input. Digital control signals can be used to create logical connections (AND, OR, XOR), which are processed internally.

In addition to the input signals for RTD temperature probes and thermocouples a 0(4) to 20 mA measurement input is available for connecting other process variables. The device has UL approval and also meets the railway industry standards for category 1B. Relevant measurement inputs, such as the Ni1000, have been integrated specifically to satisfy the requirements of this industry.

The JUMO eTRON T100 has a user-configurable dot-matrix display on which process values, parameters, switching statuses, and the electric connection diagram can be viewed.

A clearly-structured operating concept supported by additional texts (4 languages are already available in the device) as well as practical and quick wiring via vibration-proof PUSH IN terminals enable a quick and easy startup. Alternatively, the device can also be configured via a setup program and the micro USB interface, which is built in as a standard feature.

Its compact design type allows the JUMO eTRON T100 to be integrated with ease into control cabinets and sub-distribution units.
