PTC-Resistor-Relay Type MSR820V
PTC-Resistor-Relay, 8 PTC-Circuits
Share:
Part number
Product description
The MSR820V monitors up to 8 PTC-resistor-circuits at the same time. A common relay signals an alarm or an error in a sensorcircuit. The inputs can be enabled or disabled during operation. The MSR820V can also be used as a fault annuciator for collective reports.
- 1-8 PTC-circuits, each 1…6 PTC in series (max. coldresistance 1500Ω/circuit)
- Easy activating/deactivating of PTC-circuits (display with LEDs)
- 2 potential-free relay-outputs, 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
- Programmable functions:
– Monitoring of short-circuit of PTCs (OFF / ON)
– External Reset as normally closed (nc) or open (no) contact (Y1, Y2)
– Power-fail-safe reclosing lock (OFF / ON)
– Function of relay:
– K1 and K2 closed-current mode
– K1 and K2 operating-current mode
– K1 closed- and K2 operating-current-mode - Universal supply-voltage AC/DC 24 – 240 V
- Mounting on DIN-rail 35mm EN 60715 or wallmount (Option)
- Mounting height 55 mm
- Accessory: Installation Frame ER4 for panel mount
