Barber-Colman MAE1-40300 Temperature Controller

Barber-Colman MAE1-40300 Temperature Controller is a compact, relay-output device that uses a Type J thermocouple as its sensing element and provides discrete on/off regulation of a connected load. The controller’s 0 to 1600°F operating range gives engineers a broad high-temperature window to work with, allowing a user-defined setpoint to be reached and maintained by energizing or de-energizing the relay output in response to the thermocouple signal. Because it relies on a relay output rather than an analog or multi-loop control, the MAE1-40300 offers a straightforward, binary control approach—turning the connected heater, furnace, or other equipment on or off as temperature crosses the setpoint. This model is specified with a Type J input and a Relay Out configuration, ensuring compatibility with common Type J thermocouples and standard relay-driven control schemes used in industrial temperature-regulation tasks. The MAE1-40300's 0–1600°F range, Type J input, and relay-output design collectively anchor it as a focused temperature-control option within Barber-Colman's catalog for applications requiring simple, reliable single-point temperature regulation.
