3-3.1.7 REM Connector
The Genesis II Direct Digital 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 fifteen 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 Genesis II Direct
Digital Controller and the expansion modules.
The individual REMs are connected to the device by means of an RS485 Comms cabling arrangement,
as explained in 3-4 - Wiring of Remote Expansion Modules .
3-3.1.6 Pulse Counter Inputs
A single, high-speed Digital Input is provided to facilitate the counting of rectangular wave signals
(0-10VDC up to 0-24VDC, for pulse frequencies up to 1 kHz). Refer to Table 3-7 for terminal number
assignments.
Terminals 38 and 39 provide 24VDC power to the pulse source, if required. Terminals 40 and 41 are
the pulse-input terminals. The input is polarity sensitive so it is important that correct polarity be
observed.
