The devices of the Wire Breakage Monitoring series DW3 have been developed for line monitoring of mechanical switch contacts like for example N/O or N/C contacts for wire breakage and short-circuit. The proper condition of the line connection is signaled via a potential free electronic contact, which in case of failure opens (closed current condition). The switching condition of the monitored contact is also signaled via a potential free electronic contact and additionally via a relay contact (changeover). This switching condition can be inverted via Dip-switch S1-1. The switch S1-2 is functionless and is intended for later extensions. At N/O's the monitoring of a complete reporting chain with any number of contacts is possible, at N/C's only single contacts can be monitored. The devices are easily mountable on cap rail and need an auxiliary power of 24VDC. | | |
