Apollo XP95 Switch Monitor
£32.10 (inc VAT: £38.52)
Summary
The XP95 Switch Monitor with Isolator is designed to monitor the state of one or more single pole, volt-free contacts connected on a single pair of cables and to report the status to Apollo compatible control equipment. The Switch Monitor has four input states, ‘normal’, ‘fault’, ‘pre-alarm’, and ‘alarm’. The product has two visable LED’s and is Loop Powered.
Key Features
The Switch Monitor provides four input states to the control equipment: “Normal” “Fault” “Pre-alarm”and “Alarm”. These are derived from the switched resistive values. The Switch Monitor has a red LED to indicate an alarm and two yellow LEDs to indicate a switch input wiring fault or a loop short-circuit wiring fault. The Switch Monitor is fitted with a bi-directional short- circuit isolator and will be unaffected by a single short- circuit on either loop input or output.
