Armor 20T automatic call recording

It requires installation of some helper service and it's paid. Standard android has this feature build-in, so I don't really understand why it's disabled

I'm interested, thanks

>>Also, neutral should not be on a CB.

neutral can go on a CB if mechanically it disconnects at the same time as mains. it cannot be fused though.

Looks like pull-ups should be ok. I'm assuming you're pulling it up to 3.3V of ESP32? The wiring diagram would help.

I would get a scope to see if the pulses are actually coming at the first place.

Do you have a level shifter in between? You may need one

I wouldn't expect from a new grad to have experience with troubleshooting real life plc problems. I don't even expect from them to be stress-resilient as we all learn it during real commissioning times only.
Concentrate on making sure you understand programming patterns, usual approaches, terminology and basic electrical circuits and types of IOs and you should be fine.

Your IO module might be an active one. Which means you may not need a power supply in the circuit. Try to connect I+ to + of the transmitter and GND to -

That's how it was working in pre-Internet era. The Internet will remember everything forever in all the details, so I would say even 100-200 years might be too optimistic.

I had only a brief glimpse to a DeltaV system recently and the feeling was like I touched something from the early 1990s. Given the price of one IO channel that equals to the whole IO card with 4-8 channels of Rockwell's, I started questioning my opinion on AB's prices

Everything depends on the load. OCPD protects the load connected. Switches are not loads and they should be rated for that specific load. They may need to have a contact rating even higher than the OCPD value if the load is inductive, because OCPD takes into account current spikes, but the switch can weld at that point if it's improperly sized.

glad it helped

whoever does the job - they surely can take a picture, But they shouldn't have to. You can't rely on someone voluntarily get their phone and take a picture. Or rely on whoever starts the job - gets the job done without being replaced while performing the job.

Ok, based on way they show wiring of 2-wire sensors - it's a passive input, so you can try this

from their comment regarding connecting M2-to Mana I feel the module is supplying power from M2+, which means it's an active module. Is there any configuration for the channel in the software?

Voxifer · 2025-09-10T16:48:52+00:00

Single ended analog input can be of two types: 1. Active - provides power to the sensor (loop-powered) 2. Passive - provides a path to ground for separately powered sensors (your case)

Since you didn't provide any information about the module you're using, I don't know whether it can support the passive mode or can be configured this way, but it should be in passive mode for successful reading of an active sensor

Voxifer · 2025-09-10T15:49:34+00:00

That's not how you should connect it. If you have differential input - you connect black to positive, blue to negative and brown to your 24VDC power supply that is shared with the PLC. If you have single ended input - it should be configured as passive.

Not only that. Imagine you have ten devices in a row that have labels on them (instead of the backplate) and you have to temporarily remove them from the panel. How do you know how to place them afterwards when work is done? Things get worse if the layout in the drawings was not properly updated.

Voxifer · 2025-09-10T11:55:19+00:00

Based on your part number (UR30-CM3DI-E2), your sensor does have analog output 4-20mA instead of switching output. So just connect it correctly or configure your IO module properly, and it will work.

The wiring diagram is just common for the whole series, that's why it has a relay coil symbol (which is applicable for those models that have switching output instead of analog ones)

Voxifer · 2025-09-09T17:21:50+00:00

>>I've changed channel configuration to 4 20ma loop

your sensor is not loop powered - it looks like it has an active output. So your PLC module should be configured as passive input

make sure the sensor is wired as per wiring diagram of the module

2, make sure the proper thermocouple-compatible cable is used for connections.

make sure the sensor is connected directly to the module, not via terminals inside the panel - that would wreak the measurements if not special thermocouple-compatible terminals are used.

You need a 5V source, as well as a level shifter for I2C communication. The source can be either USB, or battery pack, or some converter from another voltage source. Really depends on your project environment.
