Pixsys ATR121 Controller with Dual Setpoint

Brand: Calex Electronics Limited

The ATR121 is a dual-setpoint controller with a 3-digit red LED display. 

The input is configurable for thermocouples type J, K, S and R; Pt100; PTC1000; Ni100; NTC10k (typically used in the refrigeration industry); Pt500/Pt1000 (widely used in air-conditioning); 0-1 V; 0-10 V; 0 to 20 mA and 4 to 20 mA. 

Potentiometers with a full scale value of 6 KiloOhms or 150 KiloOhms may also be used and there is a "latch on" function for quick calibration and setting of minimum, maximum and zero via the front keys.
Features
  • Low-cost single-loop control
  • Ideal for temperature, flow, level, pH or pressure measurements, and many others
  • Two setpoints for control and alarm
  • Universal analogue input for current, voltage, thermocouple, RTD, thermistor or potentiometer
  • Relay and SSR outputs
  • Highly configurable; one model suits many applications
  • CE Marked and UL Recognized
