Controller for Large ABB Door Entry Systems
Support and control a multi-unit intercom system with the ABB-Welcome System Controller MDRC, 1200mA, With Updated All On/One On Setting. The ABB-Welcome System Controller MDRC connects all system components together, allowing communication throughout the system. This larger System Controller, as opposed to the Mini Controller (sold separately), is powerful enough to manage apartment complexes and large commercial buildings. It offers Bus Voltage at 1.2A (28 VDC) and Mains Voltage at 100-240V (50/60 Hz, 1A). The controller also supports use as an auxiliary BUS power supply when connected to a Gateway (sold separately). Overheat, short-circuit, and lightning protection help prevent damage to your system.
- Provides power and communication to ABB-Welcome system components
- Operates in either "All On" or "One On" mode
- LED indicates system operating status
- Simple DIN rail mounting for clean installation
- Provides overheat and surge protection to ABB-Welcome system components
- 1 LED indicates normal working condition
- Acts as auxiliary BUS power supply when connected to gateway under certain modes
Each component, such as an outdoor station or indoor station, connects to the controller with two wires. Suitable wire (sold separately) includes doorbell wire, Cat5, coax, or any other one pair of twisted pair wiring (no need to double up). Multiple indoor stations may be daisy-chained together.
Two Modes of Operation
The System Controller operates in one of two different modes when multiple indoor stations are included in the system: "all on" or "one on". You can easily switch between modes by flipping the switch on the face of the controller.
- All On: If there is an incoming call, all indoor stations in the same residence ring together and all video screens turn on at the same time.
- One On: If there is an incoming call, all indoor stations in the same residence ring together, but only the master indoor station's screen turns on.
Internal Bus
The system controller supplies the other bus subscribers with voltage and controls communication on the 2-wire bus. Starting from the system controller, the 2-wire bus is divided into two parts — the internal bus and external bus. The internal bus is the bus for controlling devices of indoors or sub insulated system devices. In the building system, it refers to the bus line from system controller to the last indoor station. In the networked system, it refers to the bus line from system controller to the last gateway.
External Bus
The external bus is the bus for controlling devices outdoors of the same insulated system and outdoor related system devices. In the building trunk system, it refers to the bus line from system controller to outdoor station. In the networked system, it refers to the bus line from system controller to the gate station.
Installation Details
All branches of the wiring system terminate via a connected bus device (e.g., indoor station, outdoor station, system device). The controller itself is designed to mount onto a DIN rail (not included) according to DIN EN 500022.
