Need the inside scoop on the Carlo Solid State Relay RM1A40D50? What model can be replaced?

Bought RMH-40A400

Input voltage 5 32V

Control current: 5-12mA

Load voltage: 400VAC

Load nominal current: 40A

The machine is powered on, but the load is energized all the time, not controlled! After testing, the control terminal has DC 3V voltage, and the original model is OK".

Since this phenomenon occurs, it is possible that the reasons are:

1: The solid state has been broken down, i.e. damaged. So it's always on.

Because solid-state relays are electronic components, they rely on the photoelectric coupling effect to control the on/off, and if there is too high current or voltage shock at the moment of on/off, it may cause breakdown.

2: The leakage current is too large. But I feel that with your practical application, this is unlikely.

Any solid-state relay, whether working or not, will have a small leakage current as long as there is voltage loading, which is unavoidable in the solid state, (at least with current technology.) However, the leakage current is generally not so large, and it is calculated in milliamps.

If there is anything wrong with the above, please advise me.

Input Voltage:

Control current: 5-12mA

Load voltage: 400VAC

Load nominal current: 50A

Zero-crossing trigger type: LED indication.

Enter Buy 3-32VDC

Control current: 5-12mA

Load voltage: 680VAC

Load nominal current: 80A

Zero-crossing trigger type: LED indication.

Yueqing City Turtle Electronic Technology **** has production.

The proximity switches of Carlo Carlo are available by model. The "Viteri Group" has original Jalor proximity switch products!

Counterfeit ones, there are no manufacturers at all, they are all bought and sold.

The concentration is too high.

2.If there is a problem with the system, you can change the PCR mix and try it.

CHEER RM1A40D50 Solid State Relay.

Solid-state relay is a new type of electronic switching device composed of solid-state electronics, which integrates photoelectric coupling, high-power bidirectional thyristor, trigger circuit, and resistor-capacitance absorption circuit. It is used to replace traditional electromagnetic relays. Realize forward and reverse rotation control of single-phase or three-phase motors, or other controls.

No contacts, no noise. Fast switching speed, no spark interference and high reliability.

It varies according to the type of load power supply. There are two types of solid state relays: AC and DC, and they are divided into zero-crossing trigger type according to the trigger type.
