Rosslare md-25tb Secure Io Relay Module 12VDC 1A

Product Description

The ROSSLARE md-25tb is a secure I/O relay module designed to convert compatible card readers and keypads into a standalone access control system. Operating at 12 volts DC with a 1-amp power supply, the module provides two relay outputs for controlling a door strike and an auxiliary device, along with one input for a Request-to-Exit (REX) trigger. It is installed by licensed security technicians and low-voltage electricians in commercial and light commercial entry control applications. The md-25tb eliminates the need for a separate access control panel in single-door setups, making it a compact and direct solution for basic access control installations.

The md-25tb is suited for single-door access control deployments where a full panel is not required. It pairs with Rosslare AYC-series card readers and keypads, converting them from panel-dependent devices to fully standalone operation. Typical installations include interior and exterior doors in commercial offices, server rooms, and secured entry points where a REX device, door strike, and auxiliary output are the primary hardware components.

Installation Notes

Installation should be performed by a licensed low-voltage electrician or certified security technician in accordance with applicable local codes and NEC low-voltage wiring requirements. Disconnect all power to the door strike, REX device, and any connected hardware before beginning installation or wiring. Verify relay output ratings are compatible with the connected door strike load before energizing. Do not exceed the rated 1-amp supply current when calculating total connected device load.
