Inside are \u003cstrong\u003etwo relays\u003c\/strong\u003e that handle open (forward), close (reverse) and stop commands. Both outputs are isolated dry contacts rated \u003cstrong\u003e1A at 250VAC or 1A at 30VDC\u003c\/strong\u003e. That rating is for signaling a motor starter or reversing controller, not for carrying motor current directly. It links to the GCS-1 DEVICES port over RJ12 and draws \u003cstrong\u003e12V at 0.1A\u003c\/strong\u003e from that connection. On the face are Add\/Mode, Open, Close and Stop buttons for running the motor by hand. A black 6-pin terminal takes open and close limit switches plus power and data for up to \u003cstrong\u003etwo TPS-1\u003c\/strong\u003e position switches. A green 6-pin terminal lets a wall switch force open, close or stop by shorting a pin to ground. That same terminal has 12V outputs for open and close indicator lamps on a panel door. The box includes 0.5 ft and 4 ft RJ12 cables and both terminal plugs.\u003c\/p\u003e\u003ch2\u003eAutomating Greenhouse Vents With a Motor Control Dry Contact Station\u003c\/h2\u003e\u003cp style=\"text-align: justify;\"\u003eAfter snapping it onto the rail, press Add and open the Motor Setting menu on the GCS-1 to link it. From there the controller can move each vent on radiation, wind, rain, temperature and humidity. Each trigger gets a priority from 1 to 5, so a storm reading can override a heat call. For example, a grower might rank rain first so vents close before water blows in. The limit switch inputs are the real safety net against over-travel. When an open or close switch pulls to ground, that relay drops out even if the controller is still calling for movement. If a relay will not trigger, TrolMaster's first check is whether a limit switch is already engaged. Unresponsive buttons can mean one of the green override pins is shorted to ground. The communication line follows RS-485 practice, so keep total cable length within 500 m. Mount it in a dry panel, since the unit is rated for 32 to 104°F and should never get wet.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen, Close and Stop Relays:\u003c\/strong\u003e Two isolated dry-contact relays give the GCS-1 forward, reverse and stop control of a motor system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeather-Priority Automation:\u003c\/strong\u003e Radiation, wind, rain, temperature and humidity triggers each get a 1–5 priority in the controller.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLimit Switch Protection:\u003c\/strong\u003e Open and close limit inputs drop the matching relay to stop vent over-travel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTPS-1 Ready:\u003c\/strong\u003e Powers and reads up to two TPS-1 position switches for vent position feedback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocal Buttons and Wall Override:\u003c\/strong\u003e Front buttons and a 6-pin override input let staff run vents by hand.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%;
