OTC25-L 1/4 DIN FM Approved Limit Controller with Type J Thermocouple Input with Single Output
Overview
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.Features
- Type J Thermocouple Input
- Limit Temperature Control with 5 Amp Mechanical Relay
- Large Easy-to-Read LED Display Selectable for Either Limit Setpoint or Process Temperature
- ±0.3% FS Accuracy
- Optional Secondary Output
- FM Approvals
