Model Specific Description
The Athena Series 88 is a non-indicating temperature controller that can be used as a superior replacement for bulb and capillary controllers. The controller can be wired for either heating or cooling applications, has a temperature range of 0° to 300°F, has a SPDT 30A relay rated for 120/240V use, and has the option for either a PCB-mounted set-point potentiometer or a remote set-point potentiometer with either a 12" or 48" length. The 88-series controller accepts thermocouple input, and offers a 20 Amp relay output.
Note: This unit does not include the thermocouple required for its operation.
The stand-alone control is track-mounted and we also offer a NEMA 1 rated general purpose enclosure that can be wall-mounted with the included hardware and has the temperature set-point mounted on the cover for convenient access.
