Each contact supports loads up to 12A, allowing separate control of equipment such as lighting relays, exhaust fans, CO₂ solenoids, irrigation pumps, dehumidifiers, and supplemental HVAC. The board connects through RJ12 and is designed for installation inside an electrical control cabinet.\u003c\/p\u003e\n\n\n\u003cp\u003e• SKU: OM-8\u003cbr\u003e\n• Compatible Controllers: Hydro-X Pro HCS-2 and Aqua-X Pro NFS-2\u003cbr\u003e\n• Relay Outputs: 8 independent dry contacts\u003cbr\u003e\n• Maximum Current: 12A per contact\u003cbr\u003e\n• Input Voltage: 100–240 VAC\u003cbr\u003e\n• Contact Type: True dry relay contacts\u003cbr\u003e\n• Connection Interface: RJ12\u003cbr\u003e\n• Overload Protection: Independent protection for each output at the 12A threshold\u003cbr\u003e\n• Manual Override: Each contact can be manually forced ON\/OFF for up to 30 minutes\u003cbr\u003e\n• Control: Outputs can be assigned to environmental conditions, triggers, schedules and crop-calendar functions\u003cbr\u003e\n• Maximum Control Modules: Up to 50 control modules supported by HCS-2\u003cbr\u003e\n• Typical Applications: Lighting relays, exhaust fans, CO₂ solenoids, irrigation pumps, dehumidifiers, HVAC and other switched loads\u003cbr\u003e\n• High-Current Loads: Loads above 12A require an appropriately sized intermediate contactor\u003cbr\u003e\n• Mounting: Electrical control cabinet \/ panel mount\u003cbr\u003e\n• Operating Temperature: 32–104°F (0–40°C)\u003cbr\u003e\n• Operating Humidity: ≤90% RH, non-condensing\u003cbr\u003e\n• Package Dimensions: 255 × 135 × 95 mm\u003cbr\u003e\n• Included: 1× OM-8 Dry Contact Board + 1× 16-ft RJ12 Cable\u003cbr\u003e\n• Not Compatible: Original Hydro-X HCS-1 or Aqua-X Plus NFS-3\u003c\/p\u003e\n\n\n\u003cp\u003eKey Advantage: The OM-8 adds eight individually controllable high-current dry contacts to a single HCS-2 or NFS-2 system, making it particularly useful when the controller's standard outputs are insufficient. Because each contact is independently switched and protected, multiple types of equipment can be controlled separately from one expansion board.\u003c\/p\u003e","brand":"Hydro Supply Co.","offers":[{"title":"Default Title","offer_id":67610188316708,"sku":"TRLM-OM-8","price":313.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0254\/3914\/1924\/files\/dry-contact-board-for-hcs-2-nfs-2-8-individual-electrical-contacts-eac.webp?v=1791317681","url":"https:\/\/www.growitdepot.com\/products\/trolmaster-dry-contact-board-for-hcs-2nfs-2-8-individual-electrical-contacts-each-contact-up-to-12-amps","provider":"Grow It Depot","version":"1.0","type":"link"}
