THROUGH THE Cultivator's LENS Product Evaluation

  • You are adding high-amperage equipment to your facility because your current controller cannot handle the heavy electrical load of industrial pumps and lighting.
  • You are integrating professional control hardware because you need to bridge low-voltage logic with the high-power requirements of commercial irrigation.

  • The manual override button lets you force a contact open or closed for 30 minutes, which is helpful when you need to troubleshoot a device without waiting for a scheduled signal.
  • Mounting this board inside an electric control cabinet is a requirement, so ensure you have the proper housing ready before you install your high-power hardware.

  • Facility managers who installed this board say they stopped worrying about relay failures when switching their heavy-duty pump arrays.
  • Users who added this to their commercial climate system say the manual override feature saved them hours during the initial wiring and testing phase.

TrolMaster OM-8 8-Output Dry Contact Board

Managing high-amperage equipment like industrial pumps, heavy-duty solenoids, and massive lighting arrays requires more than a standard controller—it requires a robust switching hub that can handle the load without failing. The TrolMaster OM-8 Dry Contact Board is engineered specifically for the TrolMaster Hydro-X Pro HCS-2 and TrolMaster Aqua-X NFS-2 systems, providing eight independent electrical contacts that bridge the gap between low-voltage logic and high-power execution.

Each of the eight contacts on the TrolMaster OM-8 is rated for up to 12 Amps, offering the heavy-duty capacity needed for commercial-scale irrigation and climate control. Designed for professional integration, the OM-8 is intended for mounting within an electric control cabinet and supports a wide power input range of 100-240 VAC. With its built-in LCD display and unique manual override feature—allowing you to force any contact open or closed for 30 minutes—the OM-8 gives facility managers total tactile control over their most critical hardware.

Compatibility: Specially designed for TrolMaster Hydro-X Pro (HCS-2), Aqua-X Pro (WCS-2), and compatible with the broader TrolMaster ecosystem including Carbon-X.
