MCS-IO-BASE has sixteen 0-5vdc sensors inputs, ten 230vac 5amp relays outputs, and four 0-10vdc analog outputs that can be expanded to thirty-two 0-5vdc sensors inputs, twenty 230vac 5amp relays outputs, and eight 0-10vdc analog outputs by pairing with the -EXT Board within the footprint of the -BASE board.

MCS-SI-BASE has sixteen 0-5vdc sensors inputs, and four 0-10vdc analog outputs that can be expanded to thirty-two 0-5vdc sensors inputs, and eight 0-10vdc analog outputs by pairing with the -EXT Board within the footprint of the -BASE board.

MCS-RO-BASE has ten 230vac 5amp relays outputs that can be expanded to twenty 230vac 5amp relays outputs by pairing with the -EXT Board within the footprint of the -BASE board.

MCS-MODBUS-IO-12, mounts with four #6 sheet metal screws through nylon collars at corners of board. The MCS-MODBUS-IO-12 gives the MCS-MAGNUM-12 the ability to act as a Modbus Master using the Modbus RTU Protocol. This allows the MCS-MAGNUM-12 to communicate to Modbus slave devices (such as Variable Frequency Drives, Compressors, etc.) to send and access parameters. The MCS-MODBUS-IO-12 performs like an MCS-RO-BASE and MCS-SI-BASE to the MCS-MAGNUM-12. This allows the MCS-MAGNUM-12 to control 10 relays, 4 analog outputs and read 16 sensors inputs. Multiple MCS-MODBUS-IO-12 boards may be connected to the MCS-MAGNUM-12 following the MCS-I/O standards.
