Overview
The OMEGA CN381-TC is a 1/8 DIN-sized temperature controller engineered for demanding HVAC and refrigeration applications. This compact controller accepts thermocouple inputs (Type J, K) and delivers precise temperature regulation with on/off or PID control modes. The unit features an intuitive interface and is designed for panel-mount installation in control cabinets and equipment housings.
Key Features
- Compact 1/8 DIN form factor for space-constrained panels
- Thermocouple input support (Type J and Type K)
- Dual control modes: on/off and PID with autotune capability
- Digital display with clear setpoint and process variable indication
- IP65 front protection with sealed gasket enclosure
- Programmable alarm functions for process monitoring
Technical Specifications
The CN381-TC operates across standard industrial power supplies and supports temperature ranges from -40°C to 999°C depending on thermocouple type. Maximum power consumption is minimal at approximately 6 VA, making it suitable for retrofit applications. The unit provides reinforced isolation between control circuits and input sensors, meeting Class II electrical device standards.
