Multi-channel AC/DC sensitive type B residual current monitoring system RCMS type B with integrated measuring current transformers for earthed AC/DC systems (TN and TT systems) in compliance with IEC 60364-6

General description:
Monitoring system for AC, pulsed DC and AC/DC currents to monitor residual currents, fault currents and operating currents in earthed AC, DC and AC/DC systems (TN and TT systems). To increase operational and plant safety, and reduce the risk of fire, in particular with regard to IEC 61008, EN 61008, DIN VDE 0664; Draft E DIN IEC 64/1134/CD, DIN VDE 0100 part 540; IEC 60364-4-44, DIN VDE 0100-444; IEC 60364-5-548, DIN VDE 0800-2-548 and Safety and Health Protection according to EU Directives 95/63/EC, 1999/92/EC, 2001/45/EC. Remote parameterisation and indication are possible through a personal computer (standard web browser) by means of a COMTRAXX gateway (e.g. COM465IP or CP700).

Residual current monitoring system RCMS150: Remote parameterisation and indication are possible through a personal computer (standard web browser) by means of a COMTRAXX gateway (e.g. COM465IP or CP700).
6-channel evaluator for the monitoring of residual currents and fault currents in earthed DC and AC/DC systems (TN and TT systems) in connection with measuring current transformers. The RCMS150 is AC/DC sensitive (type B) in accordance with IEC 60755. Monitoring of up to 534 sub-circuits, response time for all channels max. 180 ms. 
The residual currents are recorded and evaluated as r.m.s. values in the frequency range of 0…1 kHz. The response values can be set via the connected gateways.
The user can set four response values per channel K1…6:
IΔn1 RMS (prewarning), IΔn2 RMS (alarm), IΔn1 DC (prewarning), IΔn2 DC (alarm)

If the recorded residual current falls below the release value (response value minus hysteresis) the delay on release toff begins. If the value remains below the release value after toff has elapsed, the message on the gateway is reset. If the alarm LED of the respective channel has been lit, now it goes out. A pending response value violation is output via the BMS interface with address and measuring channel indication and can be evaluated by means of a gateway.
All devices can be accessed via the network from any PC using a standard web browser (Firefox, Internet Explorer). Like this, all relevant measurement data of the monitored system are available.
All device-related parameters of the RCMS150 can be set via the gateway technology.
To ensure the device function, a continuous automatic self test is run, which monitors the function of all measuring current transformers. In the event of a device error, all alarm LEDs flash.
Mounting: DIN rail mounting according to DIN EN 60715 or screw mounting.
