  • Four ON/OFF outputs for the control of single or multi-stage compressors or fans.
  • Proportional output for speed control (inverters).
  • Output with change-over contacts for alarm control.
  • Input for pressure transmitter (0/4…20mA) or for a temperature probe (NTC10K).
  • Two digital inputs on voltage free contact for programmable function, up to three digital optocoupled voltage inputs for a complete system diagnostics.
  • Selection of the control algorithm: rotation of outputs, sequential activation, optimisation of the available power.
  • Pressure – Temperature conversion according to gas used.
  • Storage of the latest nine alarms.
  • Automatic maintenance management.
  • Connectivity to LAE supervisory systems.
