Omron H7CR-SAL Digital Preset Counter Assembly

The Omron H7CR-SAL Digital Preset Counter Assembly is a six-digit, backlit LCD panel-mount counter designed for industrial automation where precise counting of pulses, events, or cycles is required. Powered from 12–24 V DC, it accepts no-voltage (contact) inputs and provides a relay (contact) output, enabling reliable integration with sensors and switches in control panels, packaging lines, conveyors, and batching operations. With a counting speed up to 5,000 counts per second, a single preset value, and a prescale function, it supports high-speed counting while letting you set the trigger value inline. Key protection helps prevent accidental changes, and online set-value change allows adjustments without powering down the system. The H7CR-SAL is part of Omron’s H7CR series and mounts in a standard DIN 48 × 48 mm panel opening, making it suitable for retrofits and new installations alike. Common replacements for compatibility in existing equipment include Omron H7CX-A-N, H7GP-TD, and H7EC-N. Applications span industrial counting and process monitoring across packaging machines, conveyors, production counters, and batching processes where clear display visibility and stable operation are essential.
