Description
Designed for highly precise industrial counting and speed monitoring applications, the Omron H7CX-A11SD1-N serves as a highly versatile digital counter and tachometer module. Operating within standard automation panels, this 1/16 DIN panel-mounted instrument offers flexible configuration options including 1-stage preset counting, total counting, batch counting, dual counting, and tachometer functionality. Featuring a high-visibility 6-digit display, this unit ensures reliable monitoring in diverse manufacturing environments.
The device is built to facilitate seamless integration into low-voltage control circuits, accommodating both DC and AC supply voltages. Its 11-pin socket configuration streamlines installation and field replacements, reducing system downtime during maintenance cycles.
Features
- Multi-function operation supporting 1-stage preset counter, total counter, batch counter, dual counter, and tachometer modes.
- Clear 6-digit negative transmissive LCD with programmable red/green/orange backlight color changes for visual status indication.
- Flexible power supply compatibility with both low-voltage DC (12 to 24 VDC) and low-voltage AC (24 VAC) circuits.
- 11-pin socket terminal configuration enabling quick installation, maintenance, and replacement.
- NPN/PNP input compatibility selectable via internal settings.
- Key protection function to prevent accidental parameter alterations by operators.
Applications
- Packaging and bottling machinery for batch counting and throughput calculation.
- Conveyor systems and material handling lines for speed monitoring (tachometer) and part counting.
- Cut-to-length processes in metal, plastic, or textile production.
- Rotational speed measurement on industrial motors and pumps.

Installation Guidelines
- Ensure the mounting cutout matches the standard DIN 48 x 48 mm dimensions before panel insertion.
- Use a compatible 11-pin round socket (such as Omron P2CF-11 or P3GA-11) for secure mounting and wiring integrity.
- Separate signal input wires from high-voltage AC power lines to prevent electromagnetic interference from distorting counts.
- When using inductive loads on the transistor outputs, connect a surge-absorbing diode in parallel with the load.
- Maintain adequate ventilation clearance behind the module, avoiding installation in environments exceeding 55 degC.
