Options
New options
K66
Power unit with internal cooling
For a description, see section 7.1.2 (note regarding options M61, Y26, N15 and
N16 for excitation equipment is not relevant).
Note: Option K66 is only available for excitation units 6RN7031-1RH32-5AA0-Z
and 6RN7031-1RF32-5AA0-Z.
L88
Ground fault monitoring with analog output
Option L88 provides integrated ground fault monitoring with analog output for the
excitation circuit.
When compared to option L87, the insulation monitoring device offers the following
additional functions:
•
Memory with real-time clock to save alarm messages with date/time (historical
data)
•
Electrically isolated RS 485 port for data exchange (BMS protocol)
•
Line isolating relay to operate several ground fault monitors in coupled IT
systems
•
0/4 to 20 mA current output (electrically isolated)
