The SO30 is a controller for pulse-jet cleaning of bag filters. It can operate in two modes:

  • cyclic mode - time based
  • threshold mode - based on differential pressure value

Features

  • detection of solenoid valves failure (short circuit or break)
  • final cleaning cycles
  • manual testing of the solenoid valves
  • 4 valve switching sequences
  • dust collection drive control
  • Modbus RTU transmission (RS-485 standard)

Digital inputs:

  • Remote Start
  • Stop Cleaning (used with a pressure switch to pause cleaning when the compressed air pressure is low)
  • Motion Control (for the dust collecting drive)

Output relays:

  • Run
  • Alarm
  • Dust Collection Drive

The basic version (SO30A) is mounted on the T35 DIN rail. It is supplied complete with a 230V/20V, 35 VA power transformer. The controller can be also ordered in a plastic box(SO30T) or in a metal box(SO30M).
