G4Q-SS2B

Description

A variant triac output module (AC) for the LS G4 series, 16 points, rated for slightly different load current capability (0.6 A) compared to SS2A (1.0 A).

The Polar Energy Assessment:

The G4Q-SS2B appears in LS catalog excerpts as “16 points Triac output (0.6A)” — a slightly lower current variant of SS2A, for lighter loads or where cost or heat are considerations. This variant is useful when switching small AC loads.

Pros

• Provides modest AC output switching capacity with 16 points in one module: efficient for small signal AC loads.
• 16 points gives good density.

Limitations

• Lower current rating (0.6 A) limits load size; heavier AC loads would require different module.
• As with SS2A, triac outputs have load and EMI considerations.

Typical use cases

• Small AC load switching (indicator lamps, small fans) in LS G4 panel designs.
• Spare/replacement part for systems that already use SS2B and matching ratings matter.
