The C628-40002 is a digital rate meter from the Veeder-Root C628 series, designed for measuring and displaying rates from various pulse inputs. It features a large, 0.71-inch high-digit LED display that can be programmed to change color based on process events, providing instant visual feedback. The meter supports NPN, PNP, and magnetic inputs up to 10 kHz and includes a configurable debounce filter with settings for 20, 200, or 10,000 Hz. Standard outputs consist of two NPN open collector transistors and one SPDT relay, which can be tied to high and low alarm values. With its scalable display and programmable parameters, the C628-40002 is ideal for monitoring applications like conveyor speed, flow rates, and RPM in industrial environments.
