Product Description
PR electronics 2231
The PR electronics 2231 is a versatile and highly reliable trip amplifier designed for critical industrial process monitoring and control. It accepts a wide range of universal inputs, including mA, V, RTD, and thermocouple signals, providing precise and configurable single or dual relay outputs. This device is ideal for alarm and shutdown applications, functioning as a setpoint controller to trigger actions when process variables exceed predefined limits. With its SIL 2 certification and suitability for installation in hazardous areas, the 2231 ensures high levels of safety and performance in demanding environments. Programming is straightforward via the PReset PC software, allowing for easy configuration of setpoints, hysteresis, and relay functions.
Technical Specifications:
- Input Signal: Universal input for mA, V, Thermocouple (Types B, E, J, K, L, N, R, S, T, U, W3, W5), RTD (Pt100/500/1000, Ni100/500/1000), Linear resistance, and Potentiometer.
- Output: 1 or 2 SPDT relay outputs.
- Supply Voltage: Universal power supply 21.6…253 VAC, 50…60 Hz or 19.2…300 VDC.
- Safety: SIL 2 certified according to IEC 61508 for use in safety instrumented systems (SIS). Approved for ATEX, IECEx, and FM installations.
