TrolMaster Motor Control Dry Contact Station (RMC-1) - 5.51 x 3.54 x 1.97-in - 2 Relays

Isolated Relay Switching for Motorized Equipment - 5.51 x 3.54 x 1.97 in

Motorized equipment in a cultivation space needs a safe, separate switching path so your controller never carries the load directly. The RMC-1 provides two internal relays with a dry-contact output only, so it acts purely as an isolated switch for external circuits. Its contact rating is 1A at 250VAC or 1A at 30VDC.

This compact unit measures 5.51 x 3.54 x 1.97 in and weighs 0.49 lb when shipped. It suits growers who need to add motor control, such as forward, reverse and stop, to a TrolMaster control setup without building custom switching hardware. It is sold individually.

Key Features & Benefits

• Two internal relays — switch separate external circuits or handle forward and reverse motor direction.
• Dry-contact output only — keeps the switched circuit isolated from the control side.
• Manual and automated control — manage external circuits by hand or through your control system.
• Compact housing — fits easily into tight equipment spaces.
• RJ12 cable included — a 0.5 ft RJ12 cable is in the box for connection.

Who Should Use TrolMaster Motor Control Dry Contact Station (RMC-1)

Growers running a TrolMaster Green-X Greenhouse Control System who need on/off or direction control of motorized equipment will get the most from this station. It fits both commercial greenhouse operators and home gardeners with motorized vents, shades or similar equipment.

About TrolMaster Motor Control Dry Contact Station (RMC-1)

The RMC-1 is a peripheral driver from TrolMaster for terminal equipment in the Green-X Greenhouse Control System (GCS-1) ecosystem. It runs on 12V 0.1A input and operates at 32-104°F (0-40°C) and up to 90% relative humidity. A user manual is available from the manufacturer.

Frequently Asked Questions

Q: What does dry contact mean?
A: A dry contact is a switch output that supplies no power of its own. It only opens or closes a circuit, and the equipment you connect provides its own power.

Q: Can the RMC-1 power my motor directly?
A: No. It provides isolated switching only, rated at 1A at 250VAC or 1A at 30VDC. Make sure your equipment's load fits within that rating and is powered separately.

Q: Can it reverse a motor?
A: Yes. Its two internal relays support forward rotation, reverse rotation and stopping when wired for that purpose. Follow the user manual for wiring.

Q: What is the operating range?
A: It works from 32 to 104°F (0 to 40°C) at up to 90% relative humidity. Install it where it stays within those limits.

Q: What comes in the box?
A: The station ships with a 0.5 ft RJ12 cable. Check the manufacturer's documentation for any additional connection parts.
