Product Description:

The C628-40000 is a panel-mounted timer and counter that belongs to the Timers and Controllers series produced by Danaher. It monitors incoming pulses and calculates elapsed counts or time intervals. The unit energizes onboard outputs when preset values are reached, allowing repeatable sequencing of conveyors, fillers, or pick-and-place axes in industrial automation systems.

It runs from a universal mains supply of 90–264 VAC at 50/60 Hz, and its switching electronics draw only 4 W, minimizing the thermal load inside the cabinet. The high-speed input channel supports rates up to 10 kHz, allowing the unit to follow shaft encoders or photoelectric sensors without losing counts. Digital thresholds are set so that a logic ONE is any level at 3.0 VDC or higher, while a logic ZERO is accepted at 2.0 VDC or lower. Once a valid edge is detected, the internal microcontroller updates setpoint comparisons within 25 ms, providing a consistent control response for indexing or cut-to-length stations. This response allows counting to continue when sensors are spaced closely on high-speed lines and helps prevent presets from being missed during acceleration ramps.

Physical integration is simplified by a bezel that achieves a NEMA 4X and IEC IP65 seal when installed in a 45 × 92 mm panel opening, while overall dimensions of 48 × 96 × 110 mm keep enclosure depth moderate. Process values appear on a red and green seven-segment LED display with primary digits that are 18 mm high and secondary digits that are 7 mm high, ensuring readability across the machine face. Output hardware includes a mechanical contact rated at 2 A at 110 VAC and solid-state drivers consisting of two NPN outputs and one SPDT relay. For PLC-level signaling, the open-collector channel supports a maximum rating of 30 VDC and 100 mA. Relay energization takes 75 µs plus 8 ms, enabling predictable actuation of solenoids or motor starters.
