{"answer":"A dry contact can report whether an external switch or alarm circuit is open or closed. It might monitor a door, pump fault, mains-failure relay, float switch or equipment alarm. A relay output can provide a controlled contact to reset a device, trigger an alarm input, switch an interface relay or operate another low-power control circuit.\n\nThe router should not directly switch loads beyond its rated output. Pumps, motors, locks and higher-voltage circuits normally require suitable contactors, relays and electrical protection. Define the safe state if the router loses power or communications, and have a qualified person design the physical control where required.","approval_status":"draft_for_dave_review_pending_public_brain_audit","approved":false,"category":"Serial GPIO and Relay Integration","category_slug":"serial-gpio-and-relay-integration","created_at":"2026-06-10T14:40:00+00:00","daily_publish_cap":2,"date_published":"2026-06-10","display_date":"2026-06-10","drip_status":"review_seed","freshness_note":"Confirm current model specifications, carrier compatibility, stock, pricing, firmware, warranty and commercial terms directly with Comset where they affect a decision.","id":"comset-qa-038","image_ids":["comset-product-range-routers","comset-product-din-rail-mount","comset-product-cm-encl02","comset-category-hero-013-serial-gpio-and-relay-integration"],"language":"en-AU","last_updated":"2026-06-10T14:40:00+00:00","matched_image_ids":["comset-product-range-routers","comset-product-din-rail-mount","comset-product-cm-encl02","comset-category-hero-013-serial-gpio-and-relay-integration"],"public_brain_verified":false,"publish_status":"review_preview","published_at":"2026-06-10T14:40:00+00:00","question":"What practical jobs can dry contacts and relay outputs perform in a remote connectivity installation?","question_intent":"public_guidance","question_type":"technical_context","real_image_mapping_status":"mapped_to_approved_comset_catalogue_v1_6","site_key":"comset","slug":"what-practical-jobs-can-dry-contacts-and-relay-outputs-perform-in-a-remote-connectivity-installation","source":"Comset public website scrape and stable industrial-networking explanation","source_record_ids":["comset-source-0348","comset-source-0351","comset-source-0352","comset-source-0395"],"source_type":"client_source_plus_stable_explanatory_context","source_urls":["https://comset.com.au/product/digital-io-board-4-relays-dio-004","https://comset.com.au/product/digital-io-board-1-relay-dio-001","https://comset.com.au/product/5g-4g-3g-wifi-router-cm685vx"],"tenant_slug":"comset","updated_at":"2026-06-10T14:40:00+00:00"}
