Galvanic Isolation:
500 Vrms isolation between signal paths protects sensitive Mark VIe I/O modules from voltage transients and ground loops, common in industrial settings with multiple power sources. This isolation enhances system reliability by reducing the risk of electrical interference corrupting critical control signals.

Maintenance suggestions:
Perform quarterly visual inspections to check for loose terminals or damaged wires. Tighten screw terminals with a torque wrench (per GE’s specifications, typically 0.5–0.8 Nm) to prevent signal loss. Clean the terminal block annually with a dry cloth to remove dust, avoiding moisture that could cause shorts. Store spare IS230TDBTH6A boards in anti-static packaging at 10–30°C with <50% humidity, and test continuity between terminals annually to ensure functionality.
