Model MS27 - Multi-Compressor Or Multi-Fan Controller - Datasheet

Main features: 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.
