This unit
The Schneider Electric AC-1A Access Control I/O Module is a compact DIN rail-mounted unit that provides complete input/output control for access-controlled doors and portals within Andover Continuum building management systems. It integrates Wiegand card reader inputs, supervised alarm monitoring, and dual relay outputs for lock control and local alarm annunciation, enabling either distributed localized control or centralized multi-module deployments.
Technical Specifications
Input Power: 10–28 VDC (extended range, compatible with local 12 VDC supplies) Reader Power Output: Switch-selectable 5V or 12V to match various card reader requirements Relay Outputs: Two 5A Form C relays with integral hand-off-auto switching and software feedback Card Reader Interface: Wiegand input supporting up to 64 bits per card (swipe and proximity formats) Alarm Inputs: Up to three supervised inputs for door status contacts, request-to-exit sensors, tamper switches, or dual/triple-state alarm devicesKey Features
- Switch-selectable reader power supply accommodates 5V and 12V card readers
- Two independent 5A Form C relays - one dedicated to door lock control, one for alarm annunciation
- Hand-off-auto relay switching with real-time software position feedback
- Up to three supervised alarm inputs for flexible sensor integration
- Designed for natural convection cooling with no active thermal management required
- Optional NEMA 1-style Andover Continuum enclosure available
Typical Applications Localized access control at single or multiple doors; distributed I/O reducing wiring runs to central equipment; integration with request-to-exit and door status monitoring in access control systems
Compatibility & Integration Fully compatible with Schneider Electric Andover Continuum platforms. Supports industry-standard Wiegand swipe and proximity card readers. DIN rail mounting enables multi-module configurations for expanded system capacity.
