The ATR401 Dual Temperature Controller has up to 4 relays and an analog output. It also has a current transformer input and a digital input with an option for Modbus RS485.
The ATR401 can accept two inputs from most sensors, including 4-20 mA, 0-20mA, 0-10V, 0-40mV, thermocouples, RTD’s, thermistors, and potentiometers. The ATR401 has two 4 digit displays, one for the process variable and the other for the set point.
The ATR401 also has 1 relay and a solid-state output with on-off control, proportional control, proportional integral control, proportional integral, and derivative control. This controller can be set up manually or with auto-tuning.
The ATR401 is a standard 1/8 DIN 48 x 96 mm square cut-out and can withstand environmental conditions up to IP65 with an optional gasket.
The ATR401 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 a control or re-transmitter of the input signal. One input can be used as a remote setpoint.
