PID Controller


X48 is a full-featured PID controller. It accepts input from 8 types of thermocouples (B, E, J, K, N, R, S, T), Pt100, Cu53 as well as 3-wire RTD sensors, 0 - 50 mV and 4-20 mA or 0 - 20 mA linear inputs. A large LED dual-display on the front of the PID controller shows the difference in values of the setpoint and process value while 3 additional LEDs indicate the state of each relay as well as Auto/Manual status. Membrane buttons on the front of X48 allow operators to easily program up to 3 setpoints. With an error of only 0.1% of the full-scale, this is a process controller of superior accuracy. X48's electromagnetic relays trigger heating, cooling or any of 6 types of alarms - full-scale high/low, deviation high/low, inband and outband. It also retransmits an isolated output signal to other devices such as a Programmable Logic Controller (PLC) or Solid-State Relay (SSR). Signal isolation protects your devices and machines downstream of our instruments from damaging fluctuations in the input signal. X48 is an auto-tuning controller; from a cold start or a setpoint.
