Dual Channel Zener Barrier -- Model SBG54803
from OMEGA Engineering, Inc.

For most non-voltage producing devices located in a hazardous area, a single zener barrier that is negative-earth-grounded can be used for intrinsic safety. Instrumentation that produces an output (signal conditioners) usually requires two barriers, one for each "floating" lead. Here, a dual-channel... [See More]
