Input / Output Expansion Board
Part Codes: CS-AC-4311
CS-AC-4311-PCB
CS-AC-4311-PS
Introduction
The CS-AC-4311 Input/Output (I/O) Expansion Board is used to provide 8 additional
programmable inputs and 8 additional programmable outputs to a Controlsoft i-Net
installation. Each output provides voltage free changeover contacts for maximum
fl exibility. Three variants of the product is available, CS-AC-4311 (boxed), CS-AC-
4311-PCB (PCB only) and CS-AC-4311-PS (boxed with 2 Amp power supply)
The I/O Expansion Board PCB is shown below:
Cable Specifi cations:
For RS485 connections we recommend using Belden 8723 or equivalent. This consists
of 2 twisted pair cores within the cable. Each pair is screened to reduce interference
and electrical noise, plus an overall screen for additional protection. It is possible
to use screened CAT5 / CAT5e / CAT6 but we recommend using stranded cores as
opposed to solid cores to reduce the risk of cores breaking.
Note: the RS485 ‘+’ and ‘–’ connections must be run on either side of the same
twisted pair (e.g. Green and Green/White), with a separate core used for the
reference.
The total distance of an RS485 network must not exceed 1Km (1000m) from end to
end.
For wiring between the I/O Expansion Board and Locks/Request to Exit (REX) Buttons
we recommend a 22 AWG or thicker gauge alarm cable. We recommend using cables
with spare cores in case a core breaks or is damaged. Do not use CAT5 / CAT5e /
CAT6 cables to connect locks or exit buttons.
