Two-channel isolated solenoid driver barrier for Pepperl+Fuchs H-System IS system. It receives dry contact or logic-level command signals from DCS/ESD, generates stable drive current to operate field solenoid actuators. Built-in line fault detection identifies short circuit and open circuit on field wiring. Hardware isolation separates safe side and hazardous side to prevent energy transfer into Ex classified zones. Dual power modes are available for flexible cabinet layout and safety loop design.

Certification: ATEX, IECEx, FM, TÜV, CE

Solenoid drive amplifier circuit, fault detection circuit, status LED indicator, galvanic isolation assembly and screw terminal block. Common faults include drive output loss, field cable short-circuit fault, loop fault false alarm and terminal insulation breakdown.
