P48 is a cost-effective autotune PID controller. It accepts input from 8 types of thermocouples (B, E, J, K, N, R, S, T), Pt100 RTD sensors 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 2 additional LEDs indicate the state of each relay. Operators easily program up to 2 setpoints via buttons on the front of P48. With an error of only 0.1% of the full-scale, this is a process controller of superior accuracy. Temperature readings typically have an error of no more than ±1 °C. P48’s 2 electromagnetic relays trigger heating, cooling and full-scale high and low alarms. 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. Far superior to an ordinary ON-OFF controller, P48 offers Time-Proportional control, a form of pulse-width modulation that allows it to use an on/off or discrete actuator as if it were a continuous actuator capable of generating control efforts anywhere between 0 and 100%.
