Paragon Robotics has expanded its broad array of measurement capabilities with a pulse‑counter expansion module for the N‑device series platform. The DB14 expansion module can sense pulse outputs from any meter or instrument using Form A or Form C pulse signals. In addition to pulse‑counting, the DB14 provides four general‑purpose digital inputs that accept 0‑5 V signals. The module can detect pulses up to 50 Hz (minimum edge width 10 ms) on channel 1, employing hardware acceleration to reduce battery consumption. It works with a variety of pulse‑counter software packages that can scale, translate, and adjust the output data to match manual readings or data captured by other equipment. Use the DB14 to monitor gas and water flow meters, digital outputs from industrial or HVAC controllers, and true‑power measurements with Wattnode meters.

Pulse output is widely used in the metering industry because it provides precise totalized or aggregate usage data. Historically, older meters employed a mechanical switch to generate a pulse signal from a rotating dial. Modern meters typically produce digital pulse signals, although most sensors can read either format. Pulse output is categorized as “Form A” (two‑wire) or “Form C” (also known as “KYZ”, three‑wire). The DB14 is compatible with both; Form C connections require only two of the three wires to be linked to the module.
