Optimized for dynamic process monitoring, the Omron H7CX-A4S-N acts as a highly reliable industrial counting and rate-measurement module within a standard DIN-sized footprint. This 4-digit, single-stage configuration device serves dual functions as a digital counter and high-speed tachometer, making it ideal for tracking cycles, batch quantities, and rotational velocities. Equipped with screw terminals and a fast-acting transistor output, the unit integrates smoothly into low-latency control loops driven by PLCs or supervisory relays. The integrated power supply accepts universal AC voltage, mitigating the need for external step-down transformers in standard control panels.

The updated "N" suffix denotes a modernized internal processor design complying with recent RoHS directive updates and enhanced display contrast. The H7CX-A4S-N serves as a direct drop-in replacement for the legacy H7CX-A4S model. When replacing older non-N versions, verify parameter compatibility, as default gate time and input speed profiles may require brief adjustment in the configuration utility menu.
When using this module in tachometer mode, avoid routing high-voltage motor lead lines in parallel with the sensor inputs. If physical relay or microswitch contacts are used for inputs instead of proximity sensors, set the maximum input speed setting to 30 Hz via the internal menu. Setting this parameter to 5 kHz or 10 kHz with physical contacts will result in count tracking errors caused by mechanical switch bounce.
Always utilize shielded twisted-pair cabling for the sensor inputs (Input A and Input B). To prevent ground loops from injecting electrical noise into the counter's internal processor, ground the cable shield strictly at the single point panel ground instead of tying it back to Terminal 8 (Common).
Isolate and lock out all upstream electrical power sources supplying the 100-240 VAC feed lines prior to initiating any installation, modification, or wiring operations. Failure to verify zero-energy states on these contacts presents a severe electrical shock hazard and can cause complete structural destruction of the internal control components.
