Solid-State Relay HHG41 Series

FAQs

Q1. Is the HHG41 a drop-in replacement for slim relays used in interface modules?
The page lists compatibility with the 41F-1Z-C2N socket, and models are available as single-row plug-in or DIN-rail versions. Send the relay and socket part numbers currently used, and we will confirm pin and footprint compatibility.

Q2. Can the HHG41 drive a 24VDC solenoid valve or small contactor coil?
DC-output models switch 5–60VDC at 1A or 2A, which covers 24VDC valves. These are inductive loads, so use a flyback diode across the coil. For AC coils choose the AC-output models (24–240VAC or 24–440VAC). Tell us the load and we will pick the model.

Q3. Why does a downstream input stay partly on when the relay is off?
Off-state leakage is up to 5mA on DC models and 10mA on AC models. High-impedance inputs, such as some PLC inputs and LED indicators, can read that leakage as a signal. Add a bleeder resistor across the load, or contact us and we will suggest options.

Q4. How many HHG41 relays can be mounted side by side on a DIN rail?
At 2A, maximum on-state drop of 1.2V (DC) or 1.6V (AC) is about 2.4–3.2W per relay. A full rail of relays at rated load adds up. Install near a ventilation window and leave gaps. Send the layout and load and we will advise on derating.

Q5. How is a volume supply program set up for interface module manufacturers?
The MOQ is 1,600 pcs. Send annual volume, the split between DC-output and AC-output models, and mounting style (plug-in or DIN rail). We will quote against the forecast and confirm lead time.
