The E-MAX Optical Isolation Device is completely solid state and is designed to be utilized to isolate the interface between nuclear power generating station systems and monitoring equipment. They are particularly useful in instrumentation and control applications.
The digital isolator product line includes an A.C. output and two D.C. output models. The AC output unit features a single output while the DC models are available in a single or dual isolated output.
The output contact is capable of switching A.C. load from 40 mA to 500 mA at power factors from 0.3 to 1. The output contact will handle surges up to 5 amperes.
The devices are housed in non-combustible glass-filled polycarbonate cases with connecting terminals sloped at 45o angles for easy stacking of units. Input and Output terminals are easy access #10-32 studs.
