Technical data sheet for the JUMO eTRON M electronic microstat, a compact digital thermostat for temperature control with configurable heating or cooling.
The JUMO eTRON M is a compact, digital electronic microstat designed for simple temperature control applications involving either heating or cooling. It features a 3-digit backlit display and supports various measurement inputs including resistance thermometers (Pt100, Pt1000), thermocouples, and standard current or voltage signals.
Key technical capabilities include an integrated defrosting function, limit monitoring, and adjustable switching hysteresis. The device offers flexible output options with a choice of one 10A changeover relay or two 5A make contacts. Configuration can be performed via the front panel keys or through a PC interface using a setup program.
