4 - 20 mA current loop interface; Temperature controller actual value (-20 to +7

4–20 mA current interface for temperature controller actual value (−20 to +70 °C = 4–20 mA) provides a standardised analogue output for linking chamber temperature status to external monitoring, recording or process-control systems. The interface maps the controller actual-value span from −20 °C to +70 °C onto the industrial 4–20 mA current loop, supporting continuous remote indication without relying solely on the local display. Designed as laboratory equipment for climate and temperature appliances, it suits integration into building management, data-acquisition or supervisory setups where a robust current signal is preferred. Supplied as a single piece from manufacturer Memmert, the accessory complements compatible controllers and chambers used in stability, incubation and environmental testing workflows. The clear temperature-to-current assignment simplifies scaling in PLCs, chart recorders and laboratory information systems. Use this interface when you need a dedicated actual-value current loop for temperature supervision, alarm chains or external logging alongside the appliance’s own control functions. Originating from Germany, it is intended for professional laboratory and industrial environments that require a defined 4–20 mA temperature actual-value interface.
