Flameproof PID Controller

X96 (Flameproof)

X96 is a full-featured PID controller designed for use in hazardous environments. It is housed in a heavy-duty enclosure certified flameproof for gas groups I, IIA & IIB with IP65 rating - completely dust proof and a good level of protection against water. It receives input from 8 types of thermocouples (B, E, J, K, N, R, S, T), Pt100, Cu53 as well as other 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 process controller shows the difference in values of the setpoint and process value while 11 additional LEDs indicate the state of each of the 4 relays, 4 setpoints, Auto/Manual and communication status. Buttons on the front of X96, accessible through the flameproof enclosure, allow operators to easily set up to 5 setpoints - 4 for the relays as well as one for a 4 - 20 mA signal should they choose to use the linear output for control. With an error of only 0.1% of the full-scale, this is a process controller of superior accuracy. X96'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). Signal isolation protects your devices and machines downstream of our instruments from damaging fluctuations in the input signal. X96 is an auto-tuning controller; from cold start or at setpoint. Typical applications are temperature control, RH control, thyristorised heating applications, AHU control in HVAC and BMS applications.
