FAQs

1. What is the primary function of the HHJM series counting relay?

The HHJM series relay acts as a precision counting component in industrial automation, automatically connecting or disconnecting a control circuit once a preset count number is reached.

2. What is the maximum voltage capacity for the HHJM series relay?

The HHJM series supports a wide operating range, handling alternating currents up to AC 380V (50/60Hz) or direct-current setups up to DC 240V.

3. How does the HHJM series relay protect counting data during power failures?

The relay utilizes integrated EEPROM memory, which automatically retains all counting data and preset values even during unexpected factory power outages.

4. What technology ensures the counting signal stability of HHJM relays?

HHJM counting relays employ high-performance single-chip microcomputer chips combined with photoelectric isolation to shield the counting signals from industrial electrical interference.

5. What industry manufacturing standards does the HHJM relay comply with?

The HHJM series strictly complies with the technical requirements of the GB/T 14048.5 standard for low-voltage switchgear and controlgear.

6. Can the HHJM relay be used in both AC and DC control circuits?

Yes, it is highly versatile and engineered to work seamlessly in both AC circuits (up to 380V) and DC circuits (up to 240V).
