The Selec PID330 is a robust Process PID Controller built for high-performance industrial automation. It features a dual 7-segment LED display with a 4+4 digit configuration, allowing real-time visibility of both process values and setpoints. With a large 96 x 96 mm panel mount size, it provides a clear, easy-to-read interface for operators managing temperature, flow, or pressure processes.
This controller supports a wide range of inputs including Thermocouples (J, K, T, R, S, C, B, N, L, U, W, Platinel II), RTD PT100, and DC analog signals (-5 to 56mV, 0β10V, 0β20mA). The resolution is selectable from 1, 0.1, 0.01, or 0.001 based on input type, with measurement accuracy up to Β±0.1% F.S. for RTD and Β±0.25% F.S. for standard TC inputs. Control output options include Relay and Analog Current (4β20mA), while two auxiliary Relay outputs can be configured for alarms or additional setpoints.
Featuring Autotune PID and ON-OFF control modes, the PID330 offers advanced flexibility for both dynamic and steady-state applications. It includes a Single Step Ramp Soak feature for staged thermal processes, and optional RS485 MODBUS communication for SCADA or remote PLC integration. Operating on a wide 90 to 270V AC/DC power range, this controller ensures reliable performance under industrial voltage conditions.
