Flameproof RH + T ON-OFF Controller

FHX96A is a relative humidity and temperature ON-OFF controller 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.FHX96A is an ON-OFF controller. It receives 2 universal inputs which can be factory-programmed for either of two groups. Group 1 contains 8 types of thermocouples (B, E, J, K, N, R, S, T), Pt100 RTDs and 0/4-20 mA and 0-50 mV linear inputs. Group 2 contains 11 types of thermocouples (B, C, D, E, G, J, K, N, R, S, T), Pt100 and Cu53 RTDs, 0/4-20 mA and 0-50 mV linear inputs. A large LED dual-display on the front of the controller shows the difference in values of the setpoint and process value while 10 additional LEDs indicate the state of each relay, setpoints and Auto/Manual status. Operators to easily program up to 4 setpoints via membrane buttons on the front of FHX96A. With an error of only 0.1% of the full-scale, this is a process controller of superior accuracy. FHX96A'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 0/4-20 mA or 0-10 V DC 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. By including input terminals in the excitation loop, FHX96A provides power for 2-wire 4-20 mA transmitters.
