The RS PRO 2228148 is a highly reliable, panel-mounted PID process and temperature controller designed for precise thermal management in industrial automation applications. Featuring a clear dual 4-digit 7-segment LED display, it provides instant visibility of process values and setpoints alongside comprehensive status indicators (PO/M, AT, PSET, ASET1, ASET2). This versatile controller supports a wide range of universal inputs, including Thermocouple (TC), Pt-100 RTD, and standard linear voltage or current signals (0-10 mV, 0-10 V DC, 0-20 mA DC). Equipped with a 5A process relay output and dual 5A alarm relays, along with auto-tuning (AT) capabilities accessible via the front keypad, it ensures optimal process stability. Built to stringent standards with a CAT II installation category, it features plug-in screw terminal connectors for straightforward wiring and is fully CE and RoHS certified.
