Hi,   We don't have a dedicated manual for 4.1; You can use the existing one. Alex.

Hi, You need calibration for precise measurements, but for measuring 4-20mA you need to power the card with 24 V through its dedicated connector. Alex.

I'm a newbie so please excuse me if I'm asking a silly question.  I have a 4-20ma output pressure transmitter and a 24VDC loop power supply connected to the 4-20ma input of a multiio V3.2 card...

I have an older revison 4.1 building automation HAT. Is the documentation in  the user's guide version 4.2 (https://cdn.shopify.com/s/files/1/0534/4392/0067/files/BuildingAutomation-UsersGuide...

Please let me know which card you are talking about and which hardware version. A picture would be even better. Alex.

If 24V is connected to the 10–24VDC input but nothing powers up, I’d first verify polarity, terminal connections, and the board’s input requirements before trying 5V. Avoid applyi...

Well I have a new project I am planning.   I really want to use the backplate setup with the 8in-8relay, 6 RTD, 8 4-20in, 4 slot back, and compute module carrier.   On the com...

In my Pool Automation system I am using 2 Building Automation hats to control all my devices. BTW I need 2 hats becaue I utilize 24 VAC relays to all my devices. In about a 1 -2 weeks I get ainadve...

Because the IGND pin is connected between every 4 channels, you cannot do that. Because all 4 high-current channels have the same GND1 and all 4 high-voltage channels have the same GND2 (GND1 is g...

Ah I see I took "You can vary the schematics as long as current flows from OUT (pin2) to IGND(pin 1)" to mean that I could move the load in regard to "Does the relay need to be after the DC Load a...

In the first message of this topic, you posted a schematic that is the correct way to connect the load. The one you just sent will not work. In your case   - first load: +12V -> ligt (on...

Hi Alex, Please find attached.    If i turn on the light, both the light and pump comes on, and vise versa. Id like to control them individually

Hi,   If you can share the connection diagram, I might point you in the right direction.   Alex.

Good evening,  I have just gotten around to properly testing this board and it is not behaving how I would expect.    I was under the impression I could control 4 separate DC circ...

The Modbus parameters can be changed only over the I2C port. There is a serial number (processor unique ID), but it is available only via bootloader commands, which are not public. Except that I c...

I am sorry, but I didn't have a chance to look into this.  

Also, are there any modbus registers for determining make model or perhaps even serial #. are there any modbus registers for modifying unit numer comms parameters..   Regards

Hi Alex, Just checking if you have though any more around to exposing the extra built in functinality so I can do simultaneous measurements from all channels multiple stacks for a couple of seconds...

OK i opened it up in VSC and realized the identifications for the relays are the letter O and not zero.   I have it closer to working now....It will load on the v3 runtime, I have anothe...

Hi Jake, Thank you for doing that. I made the v3 libraries a long time ago, but I am not sure I understand what you are asking. Could you give me more details? Alex.
