CM-30   

 

The CM-30 controller offers system flexibility and ease of maintenance in a space-saving package. The unit’s heavy-duty enclosure helps protect its electronics from accidental damage.

The CM-30 can execute predefined control functions independently from SCADA communications.  These local control functions can provide:

  • Simple "backup" control when communications fail.

  • Pump protection features independent of your ACCOL BSAP® or PLC program.

  • Cycle counts and elapsed run time accumulators that hold their values through downloads and power outages.

The CM-30 provides 16 protected digital inputs and 6 discrete outputs. Two inputs can be alternately configured as an RS-485 port.

The CM-30 also has four 12-bit analog inputs and two SPST relays.  Each relay has an LED indicator. In addition to the relay LEDs, there are two status LEDs

The CM-30's standard quick-release screw terminals allow easy field maintenance and installation. The CM-30 will mount properly on a DIN rail using an optional DIN adapter.
