The Schneider Electric BACnet I/O Module CIO20XX10001 provides 16 digital inputs (DI) and 4 digital outputs (DO) to expand the I/O capacity of SmartX and Continuum BACnet controllers, enabling additional status monitoring and control switching without adding a full controller.
| Part Number | CIO20XX10001 |
| Digital Inputs | 16 (dry contact or voltage-free) |
| Digital Outputs | 4 (relay, 24V switching) |
| Communication | BACnet MS/TP (daisy-chain to parent controller) |
| Power Supply | 24 VAC/VDC |
| Mounting | DIN rail |
Extends BACnet controller I/O to monitor additional equipment status points (pump run, damper open/closed, alarm relay, smoke detector) or control additional On/Off outputs (motorized valves, relay coils). Common in retrofit expansions, phased project build-outs, and systems requiring third-party equipment interface.
