TN2 Negative Output Transistor Interface Module 2-Channel 3A
The TN2 Negative Output Transistor Interface Module is a rugged, opto-isolated two-channel interface board designed to safely drive and switch DC loads from industrial control systems and PLCs. Each channel provides a negative-output (sinking) FET-type transistor capable of handling up to 3A, with opto-isolation to protect sensitive control electronics from field transients and ground loops. The module includes per-channel fusing, clear LED indicators for power/input/output status, multiple mounting options and a compact footprint for easy integration into control panels and automation racks.
