ETISO: Analog Isolation Module


  • Small Size, DIN Mount
  • Three Way Isolation
  • Wide Range Power Supply Input
  • Voltage or Current Input
  • Voltage and Current (Sourcing) Output


The ETISO module is ideal for analog signal isolation, especially to avoid ground loop problems.

This product offers an economical alternative to industrial devices while interfacing a generic control system with third party equipment such as chillers, variable speed drives, telecom DC equipment, etc.

Product Description

The ETISO module is a precision analog signal isolator. It utilizes state-of-the-art specialized circuitry to provide accurate, drift free optical signal conversion. The board contains an isolated power supply that provides power to both the input and output circuitry while maintaining isolation between all circuits.

The ETISO can be factory calibrated to accept voltage or current loop input signal. It outputs both voltage (0-10VDC) and current (4-20mA) simultaneously.

The board mounts on most DIN rail styles using the attached universal DIN mounting foot.
