(each channel features 2 measuring channels: 1 x RMS, 1 x DC)
Ideal for applications with space limitations
Easy DIN rail or screw mounting to standard distribution panels
2 separately adjustable response values (DC or RMS) per channel
Continuous self monitoring
Fully shielded measuring current transformers to avoid external influences due to
magnetic fields that may cause disturbances
Compatible with Bender gateways of type COM465IP or CP9…

tiometers
– Address range 1…247, can be adjusted via the bus
– Up to 247 RCMS150-01 can be used on the bus
3.2 Functional description
The residual currents are recorded and evaluated as RMS values in the frequency range
DC…2 kHz. The response values can be set via the interface.
The user can set four response values per channel K1…6:
I
Δn1 RMS
, I
Δn2 RMS
,
I
Δn1 DC
, I
Δn2 DC
The response values I
Δn1
…
apply to the
prewarnings
,
the response values I
Δn2
…
apply to the
main alarms
