Description of Switch Amplifier

This isolated barrier is used for intrinsic safety applications.
The device transfers digital signals (SN/S1N proximity sensors or approved dry contacts) from a hazardous area to a safe area.
The input controls one active voltage output and one relay contact output with a NO contact. Unlike an SN/S1N series proximity sensor, a mechanical contact requires a 10 kΩ resistor to be placed across the contact in addition to a 1.5 kΩ resistor in series.
