Product Overview
The Omron H7CC-ASD is a 1-stage preset digital counter from the H7CC-A family, manufactured by Omron Corporation. Hengyixin Automation stocks this timer / counter at our Xiamen warehouse; orders placed before 14:00 CST ship same business day.
It counts pulses on two inputs (CP1 and CP2) from -99999 to 999999 and switches a single SPST NPN transistor output when the count reaches the set value. Maximum counting speed is 30 Hz or 10 kHz, selectable by DIP switch. Counting modes include UP, DOWN, UP/DOWN A (command), UP/DOWN B (individual), and UP/DOWN C (quadrature) inputs.
Supply is 24 VAC at 20.4 to 26.4 V, or 12 to 48 VDC at 90 to 110 percent of rated. The 6-digit white LCD is backlit, and the panel face is IP66 when used with the Y92S-P6 waterproof packing. Body depth is 59 mm. The 2-stage multifunction sibling with relay + transistor outputs is the H7CC-AU. The matching AC 100-240 V version of the same transistor body is the H7CC-AS.
Key Features
- H7CC-A-series 1-stage preset counter, 6 digits -99999 to 999999, white backlit LCD
- Counting speed 30 Hz or 10 kHz selectable, UP / DOWN / UP-DOWN A / B / C modes, prescaling 0.001 to 99.999
- NPN open-collector SPST transistor output, 100 mA at 30 VDC, external / manual / automatic reset, non-volatile EEPROM memory backup
- 24 VAC or 12 to 48 VDC supply, 48 x 48 mm 1/16 DIN screw-terminal body, 59 mm depth, IP66 panel face with Y92S-P6 packing
- SKU: H7CC-ASD
- Series: Omron H7CC-A-series preset counter (1-stage / total preset)
- Voltage: 24 VAC
Best-Fit Applications
- Bottle-counter on a small rotary filler where the H7CC-ASD counts PNP sensor pulses and trips the conveyor stop at the preset batch size
- Length counter on a cut-to-length machine where the encoder A phase lands on CP1 and the operator sets a meter target on the front-panel keys
- Spare replacement on a packaging line where the previous H7CC-A8D (8-pin socket 1-stage contact) is upgraded for the screw-terminal H7CC-ASD on the same 24 VDC
Buying Checklist
- Pick the H7CC-ASD for a 1-stage preset counter with screw-terminal wiring and a SPST transistor output on 12 to 48 VDC / 24 VAC.
- Pick the H7CC-AU instead when the counter needs 2-stage preset, batch, dual, twin counter, or tachometer duty and a relay plus transistor pair.
- Pick the H7CC-AS instead when the cabinet only has 100-240 VAC available and the same 1-stage screw-terminal body with transistor output is needed.

FAQ for H7CC-ASD
What is the Omron H7CC-ASD used for?
It is the H7CC-A-series 1-stage preset digital counter with screw-terminal wiring and a SPST NPN transistor output on 12 to 48 VDC or 24 VAC. It counts pulses from a sensor or encoder on two counting inputs (CP1 and CP2) and switches its transistor output when the count hits the preset value. Typical uses are bottle counters, length counters on cut-to-length machines, and batch counters on small packaging lines.
H7CC-ASD vs H7CC-AU - what is the difference?
Both share the same 48 x 48 mm 1/16 DIN screw-terminal body, 6-digit LCD, and 12-48 VDC / 24 VAC supply. The -ASD is the 1-stage preset / total preset counter with a single SPST transistor output. The -AU is the 2-stage multifunction counter and tachometer, with both a SPDT relay and a SPST transistor output, supporting 2-stage preset, batch, dual, twin counter, and tachometer modes. Pick the -ASD for simple batch counting; pick the -AU for dual-counter or tachometer duty.
Does the H7CC-ASD need a separate 12 VDC supply?
Yes for the sensor. The H7CC-ASD has a 12 VDC auxiliary output rated 100 mA that powers the connected proximity sensor or encoder (not on the H7CC-A8@ socket variants). The counter itself runs from the main 12 to 48 VDC or 24 VAC supply. Power consumption is 5.5 VA / 3.3 W max.
What is the maximum counting speed for the H7CC-ASD?
30 Hz or 10 kHz, selectable. At 30 Hz the minimum pulse width is 16.7 ms; at 10 kHz the minimum pulse width is 0.05 ms (50 us). The selected speed applies to both CP1 and CP2 and must be set before commissioning. For high-speed encoder counting above 10 kHz, pick a dedicated high-speed counter module (e.g. CJ1W-CT021) instead.
