PTC thermal relay type MSR820V

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
