Overview
The Omega DP25-TC is a programmable digital thermocouple monitor and controller designed for precision temperature measurement and process control. This 115VAC 6W unit features a prominent 4-digit LED display for clear, real-time temperature reading in either Fahrenheit or Celsius. The Omega DP25-TC accepts all standard thermocouple types (J, K, T, and DIN J), making it highly versatile for industrial, laboratory, and OEM applications requiring accurate setpoint-based temperature control.
Key Features
- Four-digit LED display — Clear, bright reading with selectable 0.1° or 1.0° resolution
- Dual 5 amp Form C relays — Programmable for active high/low alarms with latching or non-latching options
- Multiple thermocouple support — Accepts J, K, T, and DIN J types with automatic cold junction compensation
- Flexible analog output — Optional isolated or non-isolated output (0–10 Vdc, 0–20 mA, or 4–20 mA) for proportional control or display retransmission
- Programmable setpoints — Easy menu-driven configuration for temperature thresholds and alarm behavior
- Peak detection and memory — Front-panel peak hold function for capturing maximum temperature excursions
