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.
For further information on confi guring an i-Net installation, please refer to the i-Net
Installation Manual.

- Page 4 All 8 inputs on the I/O Expansion Board are fully programmable so any door contact, alarm signal, REX etc. can be connected to any of the 8 inputs. The function of each input is programmed via the Controlsoft Lite or Controlsoft Pro software (please refer to relevant manuals) Inputs are connected to terminal blocks J10 (inputs 0 to 3) and J12 (inputs 4 to 7).
- Page 5 Connect the Inputs Internal Mode (Common Positive) is used when the trigger device has voltage free contacts and a common positive is required. The trigger device should be less than 25m from the I/O Expansion Board. To select Internal Positive Mode, use two jumper links on J1 (confi...

Page 6: Connect The Outputs
All 8 outputs on the I/O Expansion Board are fully programmable so any magnetic lock, door strike etc. can be connected to any output. The function of each output is programmed via the Controlsoft Lite or Controlsoft Pro software (please refer to relevant manuals) Each output provides voltage free change-over contacts. - Page 7 Connect the Outputs Wiring a Door Strike to Output 0: If the breakglass is pressed, or the relay activated, power is applied to the Door Strike, which releases the door. Important! • ALWAYS fi t a MOV (8 supplied with each I/O Expansion Board) across inductive loads such as magnetic locks and strike locks to prevent Back EMF from damaging the PCB.

Page 9: Connect The Power Supply
Connect the Power Supply Step 6: Connect the Power Supply The I/O Expansion Board required 12v power to operate. The PCB requires approximately 50mA when no relays are active, plus approximately 33mA per output. Wire the power supply to terminal block J8 marked ‘12V’ and ‘GND’. Two terminals are provided for +12V and two for GND for connecting to other devices. -
