Overview
The Omega Engineering On-Off Limit Control Model 50 is a dedicated temperature control module engineered for industrial process applications requiring simple on-off switching logic. This model accepts input from temperature sensors and activates or deactivates output relays based on user-defined setpoints, making it ideal for basic temperature maintenance tasks in manufacturing, HVAC, and equipment protection applications.
Key Features
- Simple on-off control logic with adjustable setpoints
- Relay output for direct load switching
- Compact form factor suitable for panel mounting
- Manual adjustment controls for easy field configuration
- Industrial-grade construction by Omega Engineering
Technical Specifications
Verify exact specifications with product documentation or your system integrator, as this is a used unit. The Omega Model 50 typically features thermocouple or RTD sensor input compatibility, relay switching outputs, and standard industrial power supply requirements.
Typical Applications
- Process temperature limit protection
- Equipment overheat shutdown
- HVAC zone temperature control
- Industrial oven and furnace management
- Thermal process monitoring
Compatibility & Replacements
Compatible With
- Thermocouple and RTD temperature sensors
- Standard industrial 24 VDC/VAC control power systems
- Relay-based automation circuits
- General PLC I/O modules for setpoint readback
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The Omega Model 50 may directly replace other simple on-off limit controllers from Omega’s legacy product line, but model-specific matching is required.
Works With
- Analog temperature input signals from sensors
- Relay switching networks and contactor coils
