Shunt Zener diode barrier SB3 (HS94L)

This barrier is needed for an intrinsically safe installation in explosion-hazard areas connected to the in-/output module. This barrier restricts the electrical energy between non-intrinsically safe and intrinsically safe circuits. The installation has to be done according to the national safety regulations. The SB3 has to be mounted into the housing DCA1191 together with the Z3I410 installation set.
Always install shunt Zener diode barriers outside explosion-hazard areas.
