They are specified to have a max turn-on of 3. Causes the control current to stop flowing which turns off the relay. Dry contact output is generally what you get from a mechanical relay. They can directly control any SSR in the sourcing or sinking configuration. This effect is unique to the U3, but in general sinking or sourcing substantial current on any device can cause slight ground shifts. If your load is resistive light bulbs, toasters

Please see the RB12 datasheet for more details. Unfortunately I have been Unfortunately I have been running into dangerous territory.

I’d like to Useful add-on. User menu Login Register Cart Contact. Mechanical Switch Closure 2. We are working on a channel high-side output board for DB15 connectors. With an FIO line the voltage across the inputs will be about 1. I think we are going to need I think we are going to need a lot more information to figure out what is going on.

The clamping diodes help suppress switching transients, and can be particularly important when dealing with inductive lavjack such as mechanical relays or solenoids.

To control an SSR in the sinking configuration as shown above, the two important states are:.

The high side of each output switch. I think we are going to need a lot more information to figure out what is going on. Warranty, Liability, Compliance 1 – Installation 1.

Causes the control current to stop flowing which turns off the relay.

ULNor an op-amp. Once a month is the limit for these emails, but typical frequency is much less than that.

I guess i need to go to radioshack and turn a 30minute project into a 6 hour learning experience. Perhaps its possible to tell me where I have to wire the Voltage source and the relay. I think figure 5 is what you need: If you have an AC load that is inductive motors, transformers. They all look like they They all look like they should lsbjack with LabJack devices. Please recommend if not.

What can I try? Warranty, Liability, Compliance 1 – Installation 1.

I have tried hooking it up like pabjack 3 but that doesn’t work. Also when using V more attention is certainly needed. They can directly control any SSR in the sourcing or sinking configuration.

How do I write to internal flash? Might put telay SSR control voltage in a region that is not defined by most manufacturers. We use the often for AC output control, and they also have DC output relays. I was expecting this thing to give me a set of dry contacts. Beyond that, let is know what you relayy want help with. Unfortunately I have been running into dangerous territory. If controlling at high frequencies, please note the following table.

As current through the RelayDriver increases, the cutoff frequency also increases, which means that if you encounter problems controlling at high frequencies, the load resistance should be decreased to allow more current to flow through the RelayDriver.

Jameco is a good source for bargain SSRs.
