Intrinsic Safety Barrier
This Intrinsic Safety Barrier Module is the perfect complement to our Intrinsically Safe Encoders and, when used together, constitutes a completely engineered solution for encoder operation in Class I and Class II, Division 1 (Zone 0) Hazardous Environments. This single barrier provides both power and signal isolation for an incremental encoder with differential quadrature outputs and an index. This all-in-one approach saves the cost, inconvenience, and system design time needed when using separate power and signal barriers.
This barrier is galvanically isolated which eliminates the added cost of maintaining a high integrity earth ground. With differential line driver outputs, this barrier can be used to carry signals reliably up to 500 feet with a bandwidth of up to 250 kHz. It is designed around a standard DIN Rail mounting (Type EN 50022, 35 mm X 7.5 mm) for easy installation in standard enclosures. A length of DIN rail is supplied with each module. The module simply snaps directly to the DIN rail and is ready to use. The Intrinsic Safety Barrier Module is also certified to be installed in Class I, Div. 2 (Zone 2) areas.
