X72a is an on, Off controller. It is capable of being factory, Programmed for either of two input 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, And 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 at the forefront of the controller shows the difference in values of the setpoint and process value while 6 additional leds indicate the state of A maximum of 4 relays, Setpoints and auto/manual status. Operators to easily program up to 4 setpoints via membrane buttons on the front of x72a. With an error of only 0. 1% of the full, Scale, Presenting a process controller of superior accuracy. X72a s electromagnetic relays cooling or, Trigger heating 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 Delivers a 0. 10V DC output signal that connects seamlessly to including programmable, Other equipment logic controllers (PLCs) and solid-state relays (SSRs) By ensuring our devices, Signal isolation shield your downstream machines from potentially damaging variations the signal being received by including input terminals in the excitation loop, X72a provides power for 2, Wire 4, 20 ma transmitters. Features universal input up to 4 setpoints 24 v dc transmitter supply isolated retransmission output rs485 / modbus rtu 85, 265 v ac smps on, Off control
