8 PTC-Circuits
BR 1: Wiedereinschaltsperre abgeschaltet The MSR820V monitors up to 8 PTC-resistor-circuits at the same time. A common relay signals an alarm or an error in a sensor- circuit. The inputs can be enabled or disabled during operation. The MSR820V can also be used as a fault annuciator for collecti- ve reports 1-8 PTC-circuits, each 1…6 PTC in series (max. cold- resistance 1500Ω/circuit) Easy activating/deactivating of PTC-circuits (display with LEDs) 2 potential-free relay-out- puts, display of switching state with LEDs Display of state of PTC- circuits with 2 LEDs per circuit Electronic reclosing-lock (disconnectible with bridge Y1-Y2) monitoring of contacts for collective fault-reports Rated supply-voltage U s Connectable PTC-resistors Switching Point Output Relay Type of contact Testing Conditions Rated ambient Temperature range Dimensions H x W x D Attachment Protection Housing / Terminals Weight DC 20,4 - 297 V AC 20 - 264 V 8 x 1...6 pieces according to DIN 44081/82 3,3 kΩ...4 kΩ typical 3,65 kΩ 2 x 1 change-over contact (CO) AgSnO see "general technical informations" -20...+55 °C Design V4: 90 x 70 x 58 mm, mounting height 55 mm on rail NS 35 mm according to EN 60 715 or with screws M4 (option) IP 30 / IP 20 app. 180 g 2012-01-30 MSR820V Part number: T221709 AC/DC 24-240 V
