AC-Series Electronic Controllers

Two-channel universal controllers, ON/OFF or PID

Dual-output general-purpose controller for temperature and humidity control, PANEL OR DIN-RAIL.

The AC-Series covers general-purpose, dual-output control for cooling/heating and humidifying/dehumidifying applications, with PID autotuning or ON/OFF control and wide input compatibility (NTC, PTC, Pt100, thermocouple J/K, 0-1V, 0/4-20mA depending on model). Available as panel-mount with capacitive touch (AC2-5) or DIN-rail (AC2-27).

Key Features

  • Two independent output channels, ON/OFF or PID with autotuning
  • Cooling/heating and humidifying/dehumidifying, selectable
  • Main output: changeover relay or external SSR control
  • Auxiliary output on relay
  • Wide input compatibility: NTC, PTC, Pt100, thermocouple J/K, 0-1V, 0/4-20mA (model dependent)
  • Absolute or relative temperature alarms
  • Available with various mains power supply options
  • TTL or RS485 serial port with selectable ASCII/RTU protocol
  • Panel-mount with capacitive touch (AC2-5) or DIN-rail (AC2-27) format
