Description

The diagnosis and protection module enables quick diagnostics of the bus state and indicates telegram traffic via an LED. A bus failure (U < Umin) can be signalled via the changeover contact. The DSM incorporates a suppressor diode which suppresses transient over voltages and interference voltage spikes on the KNX.

The DSM/S is a rail mounted modular installation device for installation in distribution boards. The connection to KNX is established using the bus connection terminal.
