CS Technologies 16-Way Relay Expansion Board for CSEVO2 and CSEVO4 Controller - CS4322
The CS Technologies CS4322 is a 16-way relay expansion board designed to expand the universal relay capacity of CS Evolution controllers. It connects to CSEVO2 and CSEVO4 controllers in groups of 16 relays using a ribbon cable connection.
Up to 16 expansion boards can be connected to a single controller to expand relay capacity up to a total of 250 relays per controller. These boards are typically specified for building integration tasks such as lift control, lighting control, fire door interfacing, and locker control.
Key Features
- Expands CSEVO2 and CSEVO4 controller relay capacity in groups of 16.
- Provides 16 universal C-form relays.
- Normally open and normally closed contacts provided per relay.
- Includes 60 cm ribbon cable for controller connection.
- Up to 16 CS4322 boards supported per controller (maximum 250 relays total per controller).
- Can be used alongside CS4323 16-way input expansion boards (maximum 250 inputs and 250 relays).
- Commonly used for low-level lift control, lighting, fire door control, and locker control.
Important Notes
- CS4322 16-way relay expansion boards cannot be mixed with the CS4270 12 input and 4 relay expansion board on a single EVO controller.
- Lift and fire door control features are not supported with the CSEVO2 controller.

Frequently Asked Questions
- How many relay outputs does this expansion board add?
It adds 16 C-form relay outputs per CS4322 board. - Can I mix this board with the CS4270 expansion board on the same controller?
No. CS4322 relay expansion boards cannot be mixed with the CS4270 12 input and 4 relay expansion board on a single EVO controller. - Does lift and fire door control work with both CSEVO2 and CSEVO4?
Lift and fire door control features are not supported with the CSEVO2 controller.
Additional Information
- In practice, relay expansion boards like this are often allocated by subsystem (for example: one board dedicated to locker banks, one to lighting, one to lift floors) to keep wiring and fault-finding manageable.
- When planning a larger relay count, confirm the controller enclosure space, cable routing, and any relay labelling requirements before commissioning.
- For lift and fire door functions, confirm the chosen controller model supports the required feature set before finalising hardware selection.
