4-20mA Controller with Modbus

This controller has been replaced by the ATR244. A newer better and lower cost contoller. 4-20 mA Temperature Controller

The ATR243 4-20 mA Temperature Controller with Modbus has a 4-20mA control output and up to 3 relays. It also has a digital input making it the ideal choice for analog control of any loop. The ATR243 has the option of Modbus.
The ATR243 can accept inputs from most sensors including 4-20 mA, 0-20mA, 0-10V, 0-40mV, thermocouples, RTD, thermistors and potentiometer. The ATR243 has two 4 digit displays, one for the process variable and the other for the set point.
The ATR243 also has 1 relay and a solid state output with on-off control, proportional control, proportional integral control, proportional integral and derivative control. This control can be set up manually or with Autotune.
The ATR243 is 1/4 DIN standard 48 x 48 mm square cut out and is able to withstand environmental conditions up to IP65 with the optional gasket.
The ATR243 can be programmed with the front panel keypad or PC based software and multiple units can be cloned with the use of a memory card enabling high speed configuration. The PC based software can also be used to monitor several Temperature Controllers. The analog output 0-20mA, 4-20mA, and 0-10V can also be used as Control or Retransmission of the input signal.
