Tailored signal control and integration

Stop forcing your system to speak a generic language. We design around your unique signal and communication requirements to maximize responsiveness and performance.

Flexible Control Curves: Easily adjust and fine-tune motor speed curves to match your exact input parameters. Program specific units of RPM, line speed, fluid flow, system pressure, or other mechanical variables over time, completely bypassing the limitations of rigid, pre-programmed curves. For example, if your system requires a baseline pressure or a minimum operational speed for safety, you can set the motor’s idle speed to meet that requirement down to the exact percentage point. You can also adjust the acceleration and deceleration control slopes to modify your overall system response and protect mechanical components. See the graphs below for single-speed and two-speed motor application examples.

Unique Signal Inputs: Move beyond restrictive, generic 0-10V inputs. We support specialized voltage ranges (e.g., 0-3V) to seamlessly fit into your precise control architecture.

Direct PLC & BAS Reading: Streamline your setup with the ability to read a high-frequency PWM or frequency signal directly off a PLC, eliminating the need for costly, awkward external converter modules.

Single Speed Applications

One-speed motor applications

Two Speed Applications

Two-speed motor applications

Get more responsiveness and telemetry out of your existing bus architecture without upgrading your entire control infrastructure.

Data efficiency and communication

Proprietary Network Formats

We replace standard, bulky serial streams with optimized, low-latency data formats tailored for industrial and commercial environments.

Advanced Error Correction

By packing data more efficiently and adding robust error correction, we minimize latency in high-noise industrial environments—allowing us to inject real-time current, temperature, and RPM tracking into your system without lagging the network.

Reliable Communication Protocols

We prioritize high-reliability control systems. By utilizing Modbus and optimized proprietary protocols instead of direct IoT or Bluetooth integration, we minimize firmware complexity and eliminate the common points of failure associated with wireless stacks. When wireless or cloud connectivity is required, we utilize external gateways to isolate the primary control logic.

Don’t redesign your motor housing or control panel to fit a standard drive. We build the brain to fit the body.

System integration and board consolidation

Application-Specific Form Factors

We engineer custom PCBs that adapt perfectly to your specific dimensions, tight spatial constraints (such as integrating directly into a pump or fan housing), and unique high-current connector requirements. If you have the space, we can drive it.

Reduce your bill of materials (BOM), minimize failure points, and save physical space by merging separate control components into a single, intelligent unit.

System integration and board consolidation

All-in-One Architecture

Why use multiple individual boards or relays when you only need one? We can seamlessly combine multi-motor synchronization, programmable time delays, safety interlocks, brake control relays, and complex sensor inputs into a single cohesive controller.

[CRI] made the custom approach very simple to where… [we had] the convenience of trying to find something off of a shelf. It was just as easy to go the custom route.

Control Resources is a great supplier to work with; going anywhere else would make our product less reliable.
