The RCMS490-D monitors for ground fault leakage current in grounded and high-resistance grounded single- and three-phase systems. The unit can switch between two different modes of operation: Type A (AC and pulsed DC signals) and Type B (AC, pulsed DC, and pure DC). Up to 12 different channels may be monitored simultaneously by one unit and one external BENDER current transformer for each sub-system. The RCMS460-D has large response value ranges (10mA...10A for Type B, 6mA...20A for Type A).
The RCMS490-D includes a digital LCD display with harmonics analysis and data logging, seperate alarm relays for each channel, and the ability to connect the system via a FTC protocol converter to a network for monitoring on a computer.
Also required: Current transformer: W0...W5
(AC only) or WAB
(AC and/or DC)
