G6Q-SS1A

Description

8-point triac (SSR/triac) AC output module for switching AC loads (100–240 VAC), rated around 0.6–1 A per point depending on source. Designed for switching AC loads where silent, fast switching is needed.

The Polar Energy Assessment:

The G6Q-SS1A offers solid-state (triac) outputs, typically 8 channels, for AC switching applications. Unlike mechanical relays, triac outputs are silent and can switch faster but are limited to AC loads and have different derating behavior for inductive loads. LS catalogues list SS1A as the 8-point triac option in the G6/G6Q family and give the AC voltage and current class (check exact OEM page for per-point current rating).

Pros

• Silent switching and faster response vs mechanical relays.
• Good for resistive AC loads like lamps, heaters, or small motors with appropriate snubbers.

Limitations

• AC only; triacs won’t switch DC.
• Not ideal for very inductive loads without RC snubbing; triacs have idiosyncratic off-state leakage and zero-cross switching behavior.

Typical use cases

• Switching heaters, AC lamps, ovens, or other resistive AC loads where silent, repeatable switching is preferred.
