Selection & installation notes
- Maximum switching voltage, current and power are separate limits. Confirm shared-COM current and simultaneous-channel derating; do not multiply the 6 A relay rating by the channel count.
- The source uses both short and expanded order-code formats. Confirm the exact voltage and terminal order code before purchase.
- Optional output suppression must match AC/DC load voltage and energy. Isolate all supplies before releasing the relay latch or unplugging connectors.
