Input coupling relays

Four binary inputs of the SINAMICS DC MASTER Converter CU1/-X177:11...14 are
provided for the customer via input coupling relays =U1-XK-K11...-K14 for external
activation. The relays are executed as terminal relays. This means that it is possible to
connect the customer cables directly to these terminals -XK.
As standard, the coupling relays are designed for a coil control voltage of 230 V AC or, with
option C51, for 24 V DC. The function of the relays -K11 and -K14 is user defined; the relay -
K12 is assigned the ON/STOP function, the relay -K13 is assigned "controller enable".

Output coupling relays

One binary output of the SINAMICS DC MASTER DC Converter, CU1/-X177:20, is provided
for the customer via output coupling relay =U1-XK-K15 and its floating changeover contact.
The relay is designed as a terminal relay. This means that it is possible to connect the
customer cables directly to these terminals -XK. The function of the relay is user defined,
whereby the device fault message is preset.
With option Y60, additional output coupling replays can be ordered.
