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
