The SIP12 Pin package ISOEM-S Series Analog Active Signal Isolated Transmitter/Distributor is a signal module with an electro-magnetic hybrid integrated circuit. It includes a multi-isolation DC/DC transformation power and a set of electro-magnetic coupling analog signal isolated amplifier/transmitters. By employing internal isolation technique, the isolated voltage is up to 3000VDC.
This series achieves isolated conversion for industrial site signals without the need for gain/zero adjustment. The isolated power supply in the input end can distribute power to displacement, resistance, and other passive two-wire/three-wire sensors.
