Digital I/O module

Modbus RTU8-I/Omodular

Product overview
Access Portal cluster modules clip into or install up to 150 metres from a cluster controller to provide modular reader and I/O expansion for access control installations. Single-click installation completes power and communication cabling when clipped into the controller, or modules can be positioned remotely to suit site layouts.

Mix and match
Install up to eight modules of any variant per cluster controller to adapt to different site requirements and reduce costs by using standard hardware components.

Variants

• OSDP: global open standard providing enhanced security, reduced cabling and installation complexity. Supports two readers per module and offers Wiegand output for upgrade compatibility.
• Wiegand: widely used communication protocol for access control. Manages two Impro readers per module and supports third-party readers such as biometrics, ANPR and long-range devices.
• IO8: provides eight digital inputs and eight relay outputs for integration with elevators, intrusion systems, lighting control and other site equipment.

Features

• Hot-swappable modules for rapid replacement
• Up to eight modules per cluster controller
• LED diagnostic indicators for quick status checks
• End-of-line sensing for tamper/additional security detection
• Onsite firmware upgrade capability
