3 Digit Temperature Controller, ATR121

General Description

The ATR121 Temperature Controller is a 3 digit display PID controller with up to 2 relay outputs, Solid State Output and an option to be a Modbus RS485 Slave device. The ATR121 is only 1 1/4 x 2 7/8" cut out and is able to withstand environmental conditions up to IP65 with the optional gasket.
The ATR121 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 ATR121 has various sensor inputs including Thermocouples, RTD's, mA, Voltage, Thermistors and Potentiometers. Desired control is maintained with PID and auto tuning.
