3-3.2.6 REM Connector

The MPCII Mid Points Controller has the facility for I/O expansion using Remote Expansion Modules

(REMs). Each REM provides an array of points which can be connected to a sub network up to 600

metres in length.

The fieen REMs can be made up of any mix of the available types with one exception - the MP REM.

The MP REM can only be addressed between 1 and 8 and only 8 MP REMS can be used.

The REM connector is a 4 way terminal connection that provides access between the MPCII Mid Points

Controller and the expansion modules.

The individual REMs are connected to the device by means of an RS485 Comms cabling arrangement,

as explained below in 3-4 Wiring of Remote Expansion Modules.

Refer to Table 3-12 for Analogue Output terminal number assignments:
