CS 12 Input and 4 Relay Output Expansion Board

CS 12 Input and 4 Relay Output Expansion Board

The CS4270 is a 12 monitored input and 4 relay expansion board designed for CS Technologies EVO controllers. It expands alarm input capacity while adding relay outputs for auxiliary control functions.

Key Features

• Connects to the controller using the included ribbon cable.
• Up to five alarm expansion boards can be connected to one EVO controller.
• Adds twelve monitored four state inputs including open, closed, open circuit, and short circuit.
• Input monitoring can be disabled via software.
• Adds four C Form relay outputs.
• Each relay provides normally open and normally closed contacts.
• Maximum 24 volts direct current switching per relay.
• Cannot be combined with 16 way expansion boards on the same EVO controller.
• Requires version 3.5 board.
• Designed and manufactured in Australia.

Frequently Asked Questions

• Can this be used with 16 way expansion boards?
  No. CS4270 cannot be combined with 16 way expansion boards on the same EVO controller.
• How many boards can be connected?
  Up to five CS4270 expansion boards can be connected to one EVO controller.
• Do the inputs require resistors?
  Yes. Four state monitoring uses two 10 kilo ohm resistors per input.

Additional Information

• This board is commonly used where both additional monitored inputs and relay outputs are required without upgrading the controller.
• If only input expansion is required, a 16 way input board may be more appropriate.
• Relay outputs are limited to low voltage switching only.
