Diagnosis and Protection Module, MDRC Bus Connection Terminals

Enables quick diagnosis of the bus state and indicates telegram traffic via an LED. A bus fault is indicated by normally open and normally closed contacts.The DSM also suppresses transient overvoltages and interference voltage spikes on the bus thus protecting the ABB i-bus For connecting bus devices to the ABB i-bus
® as well as for looping through or branching the bus cable. Available in black/red for use as EIB bus connecting terminal and in white/yellow for use as a connecting terminal, for auxiliary voltages and signals. BUS KLEMME red/blackGH Q630 1901 R0001 20 – KLEMME white/yellowGH Q630 1902 R0001 20 –
