The device is a modular installation device (MDRC) in Pro M design. The module width of the device is
four space units. It is designed for installation in distribution boards on 35 mm mounting rails.
The device is supplied via the bus and requires an additional auxiliary voltage, either 24 V DC or Power
over Ethernet (PoE). We recommend using a power supply from our range. When using timer functions,
date and time must be provided via KNX/TP.
The device connects to the ABB i-bus
®
KNX via the front bus connection terminal.
Engineering Tool Software (ETS) is used for physical address assignment and parametrization.
Once the bus and auxiliary voltages are connected, the device is ready for operation.
