LABJACK RELAY DRIVER

This effect is unique to the U3, but in general sinking or sourcing substantial current on any device can cause slight ground shifts. The four pins plug directly into the 5. I guess i need to go to radioshack and turn a 30minute project into a 6 hour learning experience. Once a month is the limit for these emails, but typical frequency is much less than that. Warranty, Liability, Compliance 1 – Installation 1. Please see the RB12 datasheet for more details.

RB12 Relay Board | LabJack

I think we are going to need a lot more information to figure out what is going on. It would also have been nice if the common point for the two switches could have floated rather than be tied to ground.

I was expecting this thing to I was expecting this thing to give me a set of dry contacts. Shopping cart Your shopping cart is empty. Instead now I have to investigate and learn all kind of info that I dont care about. That is going to be almost any relay out there. Causes the control current to stop flowing which turns off the relay.

When connecting a relay or other type of load, there will be a voltage drop depending on current. Per the specifications in each devices datasheet, the DACs can generally source more current that digital outputs. Connect the load voltage to this terminal to bias the internal clamping diodes on each switch.

The clamping diodes help suppress switching transients, and can be particularly important when dealing with inductive loads such as mechanical relays or solenoids. It operates in a similar way, but has 12 channels, high side switching, and digital isolation. Both of these in the 1.

Mechanical Switch Closure 2. They can source enough current to control almost any SSR and even some mechanical relays, and thus can be a convenient way to control 1 or 2 relays. We use the often for AC output control, and they also have DC output relays. Shopping cart Your shopping cart is empty. A resistor between 10k and 27k should be used Please recommend if not. Every LabJack is backed by our labjaco Legendary Support, for life.

Unfortunately I have been Unfortunately I have been running into dangerous territory.

They all look like they They all look like they should work with LabJack devices. Jameco is a good source for bargain SSRs.

The low side of both output switches. Warranty, Liability, Compliance 1.

We are working on a channel high-side output board for DB15 connectors. Unfortunately I have been running into dangerous territory. Would be nice having a clear Would be nice having a clear recommendation what relay should be connected and what not.

Normal Close is possible NC: I guess the electronic relay I’m using directly on the U3 will work fine but a circuit diagram is lacking showing their usage here with the relay driver. Both of these are well above the 3. Mechanical Switch Closure 2.

I have tried hooking it up like figure 3 but that doesn’t work. Whatever the load is, that is on the load side, so it is isolated from the LabJack side, so the key point is just to keep it that way. Also when using V more attention is certainly needed. To continue this and discuss options, I would post on the forum and provide any more details you can gather about the control circuit for the MP To control an SSR in the sinking configuration as shown above, the two important states are:.
