Introducing Kenton’s MOD22017 Alarm Isolation Unit

For SCADA Telemetry on Hot-Sites

The MOD22017 Alarm Isolation Unit is a 6 channel alarm isolator unit for “hot site” isolation of alarms on high voltage and medium voltage plants. The isolator is designed to isolate DC alarm contacts on “hot“ equipment via field wiring with the electronic inputs of monitoring equipment (SCADA, PLC).

Potentially under fault or flashover conditions the field sensing contacts can be raised to many thousands of volts above ground potential, which would damage low voltage monitoring equipment.

The alarm isolator unit is mains powered with a nominal 50V DC feed to remote alarm contacts via field wiring. These contacts in turn activate the isolated relays in the alarm isolator. Up to six isolator relays can be fitted to the DIN rail in the unit, and easily replaced if required. The unit will operate on field wiring up to a maximum loop resistance of 1000 ohms.


Product Highlights

  • Galvanic isolation of 15KV RMS
  • Protects SCADA interfaces from high field ESD
  • Sense loop up to 1000 ohms
  • LED loop indication
  • Up to 6 independent channels
  • Low power
