DH48J-11A Digital Counter Relay 11-Pin 12V–380V with Base
DH48J-11A Digital Counter Relay 11-Pin 12V–380V with Base
DH48J-11A Digital Counter Relay – 11-Pin, LED Display, Power Failure Memory
The CKCTINNER DH48J-11A Digital Counter Relay is a robust, versatile 4-digit counter relay designed for industrial and DIY electrical control applications. Featuring an 11-pin configuration, a bright LED display, and a counting range of 1 to 999,900, this relay is built to handle both contact and sensor signal inputs with ease. The Power Failure Memory Function ensures your count is never lost during an unexpected power interruption — picking up right where it left off when power is restored.
Compatible with a wide range of AC and DC voltages (12V to 380V), and supplied complete with a mounting base, the DH48J-11A is a CE-certified solution ready for panel or device installation. Made in Mainland China.

Frequently Asked Questions
Q: What voltage options does the DH48J-11A digital counter relay support?
A: The DH48J-11A supports a wide range of voltages. For AC, it works with 380V, 220V, 110V, 36V, 24V, and 24–240V universal ranges. For DC, it is compatible with 12V, 24V, and 24–240V. This makes it highly flexible for diverse industrial and electrical control setups.
Q: Does the DH48J-11A retain the count after a power failure?
A: Yes. The DH48J-11A features a built-in Power Failure Memory Function. When power is restored after an interruption, the relay resumes counting from the last recorded value — preventing data loss and avoiding the need for manual re-entry.
Q: Is the 11-pin mounting base included with the relay?
A: Yes, the 11-pin socket base is included in the package, allowing for straightforward panel or device-type installation right out of the box.
Q: What is the maximum counting speed of this digital counter relay?
A: The DH48J-11A supports two counting speed modes: low speed at up to 30 counts per second, and high speed at up to 300 counts per second, with a minimum input pulse width of 15 ms.
