OTC25-L 1/4 DIN FM Approved Limit Temperature Controller

OTC25-L 1/4 DIN FM Approved Limit Controller with Type J Thermocouple Input with Single Output
    Price Starting At: $335.00


    The Athena OTC25-L is a 1/4 DIN panel mounted, digital Limit Temperature controller The Limit Setpoint determines the temperature at which the limit output will become inactive, interrupting power to the process. The OTC25-L controller accepts a Type J thermocouple input, and a large easy-to-read digital LED display is selectable for either setpoint or process temperature. Limit control versions (OTC25-L) may only be ordered with electromechanical relay (Type "B") outputs in Output 1.
