Control Panels & Expansion Boards

The current collection contains the EX0808 auxiliary I/O expansion board. Use it to assess additional inputs and relay outputs for a compatible access-control system; a standalone main controller is not currently represented in this collection.

Count the additional I/O points

One EX0808 provides eight inputs and eight relay outputs. ZKTeco documents up to eight boards on a supported inBio Pro or C3 Pro panel, so determine the required I/O count and host arrangement before allocating boards.

Check host support and installation components

Confirm the exact panel, management software and communication mode. RS485 wiring alone does not establish protocol compatibility. Allow separately for enclosure space, the board's power requirement, connected-load ratings and cable routing.
