Analog Isolator

  • High Reliability
  • High Accuracy and Linearity
  • Simple Installation

The Analog Optical Isolator module is a single isolated current in / current out or voltage in / voltage out channel of physical separation and electrical isolation for establishing and maintaining the independence of Class 1E equipment from non -Class 1E instrumentation circuits. Input-to-Output isolation has a steady-state isolation capability of 2500 volts AC rms. This isolation will be maintained between:
a) input to output signals
b) input to output power
c) output signal to input power

The devices are housed in non-combustible glass-filled polycarbonate cases with connecting terminals sloped at 45o angles to facilitate stacking of units. Input and Output terminals are easy access #10-32 studs.

All units are subjected to a burn-in test for a minimum of 100 hours at a temperature of approximately 140oF under load.
