LABJACK RELAY DRIVER

Mechanical Switch Closure 2. I’d like to see the full schematic for it, however. For example, the FIO sinking configuration above sinks about 2. Although this connection is optional, there is usually no reason not to use it. Warranty, Liability, Compliance 1 – Installation 1. This wants to be actuated by having a switch placed between its internal 12V power supply and its relay. It seems like small leakage currents can cause the internal diode of some SSRs to remain in a “semi-on” state.

It gets more complicated to make something that can be high- or low-side. A resistor between 10k and 27k should be used Shopping cart Your shopping cart is empty. The four pins plug directly into the 5. The clamping diodes help suppress switching transients, and can be particularly important when dealing with inductive loads such as mechanical relays or solenoids. The limit on how much current you can draw from VS is typically about mA Appendix Abut if you are doing delicate analog measurements with the U3 you might not want to draw so much current from it.

As current through rflay RelayDriver increases, the cutoff frequency also increases, relag means that if you encounter problems controlling at high frequencies, the load resistance should be decreased to allow more current to relsy through the RelayDriver. Might put the SSR control voltage in a region that is not defined by most manufacturers. It seems like small leakage laabjack can cause the internal diode of some SSRs to remain in a “semi-on” state.

What version would be best?

LJTick-RelayDriver

Extra notes about Digital Outputs Note lajback sinking excessive current into digital outputs on the U3 can cause noticeable shifts in analog input readings. Optional Configuration to fix pull-up or turn off issues: Jameco is a good source for bargain SSRs.

The high side of each output switch. The LJTick-RelayDriver is designed to drive relays, including mechanical relays, so if you use the LJTRD to drive a labjakc relay that is the lowest cost way to get dry contact output. Also when using V more attention is certainly needed.

Additionally, we provide all the software you need to get the most out of your LabJack. They all look like they rekay work with LabJack devices.

I have tried hooking it up like figure 3 but that doesn’t work. This is not common, but due to the details of some SSR’s input circuitry, they can’t be modeled properly as a simple resistor.

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 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.

I think we are going to need a lot more information to figure out what is going on. I was expecting this thing to I was expecting this thing to give me a set of dry contacts. Says 10 ohms above, so we need to check that.

Instead now I have to investigate and learn all kind of info that I dont care about. I guess i need to go to radioshack and turn a 30minute project into a 6 hour learning experience. The PS12DC tops out at 1. How do I write to internal flash?

Perhaps its possible to tell me where I have to wire the Voltage source and the relay. Shopping cart Your shopping cart is empty. I think we are going to need I think we are going laback need a lot more information to figure out what is going on. Would be nice having a clear Would be nice having a clear recommendation what relay should be connected and what not.

Unfortunately I have been running into dangerous territory. I think figure 5 is what you need: They are specified to have relsy max turn-on of 3.
