Pertronic Solenoid Interfaces allow analogue addressable control modules and the Pertronic Agent Release Controller to activate and supervise a wide range of solenoids.
There are two groups of solenoid interfaces:
These interfaces have end-of-line (EOL) resistors which allow reverse-polarity fault supervision systems to detect open-circuit faults including disconnected or open-circuit solenoids. The fault supervision system will also identify a short-circuit fault in the cabling between control module and solenoid interface, but not a short-circuit across the solenoid itself.
NOTES:
Usable current capacity is limited by the capacity of the control module’s relay output.
Pertronic Solenoid Interfaces are not suitable for solenoids with built-in bridge rectifiers or back emf diodes. A bridge rectifier or back emf diode may prevent the interface reliably detecting an open circuit fault in the solenoid. The solenoid interface incorporates appropriate back emf protection.
