This general purpose relay is chosen for circuits where a small control signal has to switch a real AC or DC load rather than a signal-level contact. It is specified for new appliance and panel board designs, and for replacing a failed relay on equipment already in the field. Because the working voltage and current follow the application, the contact arrangement you specify is what makes the part fit the board.
Which form you need depends on what the load has to do while the coil is not energised. Form 1A is a normally open contact that closes when the coil is energised - the choice for a load that should run only on command, such as a heating element or a fan. Form 1B is the mirror image, a normally closed contact that opens on energising, and it suits a circuit that has to stay live by default and be interrupted only for a specific condition. Form 1C is a changeover contact that moves a common terminal between two contacts, which covers two-state switching or routing a signal one way or the other. All three use the same body, so the board footprint stays the same whichever form you specify.
YongNeng is a relay manufacturer supplying signal relays, latching relays and high-power relays, together with a high-voltage DC contactor line that runs from 16A up to 400A. Because our range covers everything from light switching duty to heavy DC loads, buyers can consolidate several switching positions with one supplier instead of sourcing each rating separately. Power relays are offered in sealed and open construction, and contact wiring is arranged for straightforward installation. Tell us the current rating, switching duty and mounting space your project needs, and we will help you match the right relay or contactor to your build.

Yes. The contact set is rated for resistive AC and DC loads, so a single part can serve either type of circuit. Tell us the working voltage and the load type and we will confirm the fit.
A small transistor stage or a logic-level output is enough to switch the coil, so no separate driver module is needed on the board. When the coil is driven from a DC rail, a flyback diode across it is normal practice: it protects the driver from the reverse voltage spike and slightly extends release time.
The published contact rating applies to resistive loads. Motors, solenoids and capacitive-input supplies draw an inrush well above their running current, so those duties usually need headroom or a heavier switching device. Send the load type and current profile and we will advise on the right fit.
They do different jobs: this industrial relay switches a moderate load from a small control signal, while a contactor is built for much heavier currents and larger contact gaps. Many panels use both, with the relay on the control side and the contactor on the main power circuit.
Yes - this is the 16 A version, and the same range covers heavier power relays and high-voltage DC contactors. As power relay manufacturers we build the range ourselves, so tell us the load and duty cycle you are working with and we will point you to the model that fits.
Keep them in the original packaging until assembly, in a dry, dust-free area away from corrosive atmospheres. Leave the terminals undisturbed while handling, and check the data sheet again before a production build if stock has been held for a long time.
