Your cart is empty. 5V 1 Channel High Level Solid Relay Module With Fuse 250V 2A
Introduction:
1. 5V 240V solid state relay 2A, output with resistance type fuse 240V 2A.
2. Dimension: 25*34*25 (length * width * height); weight: 13g
3. Input power supply: 5V DC (160MA)
4. Input control signal voltage: (the state of the 0-2.5V low level relay OFF), (the state of the 3-5V high level relay ON)
5. Blue KF301 terminal is connected to the line of control more convenient.
INPUT PART:
DC+: Connect the power supply positive (press the relay voltage power supply)
DC-: The cathode of a power supply
CH: Relay module signal trigger end (high level trigger effective)
HIGH LEVEL AND LOW LEVEL OF MEANING:
High level trigger refers to the signal trigger end (IN) had a positive voltage andthe negative pole of the power supply is usually between, and the triggering end of a trigger connected with the positive pole of a power supply, when the triggerend has a positive voltage or reached the trigger voltage, the relay is attracted.
Low level trigger refers to the signal triggering voltage between the end and the negative electrode of the power supply is OV, or trigger terminal voltage lower voltage than the positive power supply voltage, low to can trigger, so that relay,is usually the cathode of the power supply and the triggering end of a trigger mode connection, so that the relay is attracted.
ELECTRICAL PARAMETERS:
The static current voltage version of the working current of trigger voltage,trigger current
5V 0mA 12.5mA 3.3-5V 2mA
Note:Power supply must be DC, the voltage of the supply power voltage should be suitable for the module.
Package Includes:
4 * 5V 1 Channel High Level Solid Relay Module

I am using these to control 400 Hz AC rather than 50 or 60 Hz. 400 Hz should not be a challenge for a triac-type device. But these are not specified for hat frequency, but seem to work fine. Seems a good value for the price. I'd not recommend exceed the current and voltage ratings, however.

These don’t fully close specially if used on DC. Works well on AC loads above 100v. But they still leak! not a big fan of hiletgo parts.

These do work, and seller got them to me quickly, however ... Notice that the relay sits perpendicular to the connectors. This makes the high voltage side too close to the low voltage connector pins and traces. IMO It's a poor circuit board design that I would not ever use for any permanent installation inside an electrical box etc. This makes them useless to me other than maybe for testing lower voltage DC circuits before installing them using a different SSR with better design. Simply rotating the SSR on the PCB by 90 degrees would have been a much better layout

Circuit board layout designers did not take into account usual and customary high voltage spacing rules. The high voltage fuse is placed much too close to the low voltage control signals. The SSR should have been placed 90 degrees from present orientation with the low voltage end nearest the low voltage input. And similar for the high voltage switch end. I will not use for my home automation project. Not worth the risk of hurting someone.

As title says. This does not work well with DC.
