Description
Introduction
The ABB MT/S8.12.2M (Product ID: 2CDG110110R0011) is an 8-fold MDRC security terminal designed for the monitored connection of security technology sensors to the ABB i-bus® KNX system. Functioning as a signalling group terminal, it provides eight dedicated input channels (zones) to interface security sensors directly into the KNX network. This device is part of our KNX System Components range.
Engineered for DIN-Rail mounting, this unit can function as a stand-alone security system or operate in combination with a security module or intrusion alarm panel featuring a KNX interface. It includes 3 outputs, manual operation capabilities, and requires an auxiliary 12 V DC SELV power supply, such as the ABB NTU/S 12.2000.1.
Key Features
- 8 input channels (zones) for monitored security sensor connections.
- 3 outputs with maximum switching current of 0.6 A.
- 12 V DC output voltage (U out).
- Requires external 12 V DC SELV power supply (e.g., NTU/S 12.2000.1).
- Supports manual operation on the unit.
- Low power loss rated at 1.2 W.
- DIN-Rail mounting (MDRC design).
- CE conformity declared under document 2CDK513014D2701.
Benefits
- Monitored Input Zones: Features 8 input channels specifically designed for monitored sensor connections across security systems.
- Flexible Security Architecture: Operates effectively as an independent stand-alone security system or alongside KNX-compatible intrusion alarm panels.
- Integrated Outputs: Includes 3 outputs with an output voltage of 12 V DC to support auxiliary system integration.
- Local Diagnostic Control: Equipped with manual operation capabilities directly on the device.
- Standardized MDRC Form Factor: Built for convenient DIN-Rail mounting in standard distribution cabinets.
