I'm trying to wire this module. I'm just confused as to what the difference is between the two triangles and how would I connect them?

\$\begingroup\$ Would you please add in the make and model of the thing you are using, and preferably a link to manual to figure out what it does. \$\endgroup\$Justme– Justme2022-06-14 20:25:55 +00:00Commented Jun 14, 2022 at 20:25

1\$\begingroup\$ Ignore everything on the right; that's all stuff happening inside the unit. For wiring it, just follow the text on the left. The battery is your 24V source. \$\endgroup\$rdtsc– rdtsc2022-06-14 20:58:18 +00:00Commented Jun 14, 2022 at 20:58

1\$\begingroup\$ the difference is equal to the battery voltage \$\endgroup\$jsotola– jsotola2022-06-14 21:52:41 +00:00Commented Jun 14, 2022 at 21:52

That appears to be internal to the module, likely +24VDC and 0VDC. If so then you should only need to deal with the pinout on the left.

\$\begingroup\$ Thank you! Just for future reference, what exactly does the white triangle and black triangle stand for? \$\endgroup\$Chris– Chris2022-06-14 21:03:53 +00:00Commented Jun 14, 2022 at 21:03

1\$\begingroup\$ @Chris You need to ask the manufacturer about that. Maybe they don't know either why they chose those symbols. \$\endgroup\$Justme– Justme2022-06-14 21:44:29 +00:00Commented Jun 14, 2022 at 21:44

The white triangle is the analog common reference net, often called “ground” or “0V”.
The black triangle represents a connection to the positive supply rail.
The connection of two lines to the black triangle is unfortunate and confusing. It looks as if the black triangle was some sort of a differential stage or an op-amp. It’s not. The two (+) lines should first connect together using a dot, and only a single line should be shown entering the black triangle.
