The ATR142 Ramp generator and Soak Temperature Controller is a 4 digit PID controller with a local display for the measured variable and the setpoint. The ATR142 can have 3 set points. Which can be triggered by a digital input. The 3 set points can be used to build a temperature profile that drives the temperature up and down at predetermined intervals. Also, the temperature can be maintained for a period of time and then cooled down at a predetermined time period. The ATR142 can have up to 2 relays, a Solid State Output and an option to have a Modbus RS485 output. The ATR142 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 ATR142 can be programmed with 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 ATR142 has various sensor inputs including Thermocouples, RTD's, mA, Voltage, mV, Thermistors and Potentiometers. Desired control is maintained with PID and auto-tuning.
