Flameproof ON-OFF Controller

X48AV1 (Flameproof)

X48AV1 is an 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. It receives 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. Operators easily program up to 3 setpoints via membrane buttons on the front of X48AV1.X48AV1 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, X48AV1 provides power for 2-wire 4-20 mA transmitters.
