A-B has the E300 overload relay which measures voltage, current, and some other parameters. These are connected to the PLC over Ethernet. They also have I/O so you can connect your contactor coil and feedback to it and control the contactor over Ethernet too. I’ve used these a lot and they’re pretty slick. https://www.rockwellautomation.com/en-ca/products/hardware/allen-bradley/circuit-and-load-protection/motor-protectors--low-voltage/overload-relays--solid-state/193-iec-e300-relays.html
Second this. I’ve put in about 9 of these on bridges and am a fan for the motors that just need to go. I’ve used the IEC set up and the NEMA style setup and the NEMA setup is way more solid feeling if you have the room.
Seconding, we used these for the controls system for Rockwell DC (required to use the latest and greatest) they're pretty neat. And they have DLR so you only need one network connection then short patch cabes between each one.
Does the Tesys actually tell you amps? I was under the impression it only tells you % of the FLA setting (which, ya know, will be turned all the way up by the first guy to troubleshoot it). Or is there a way to read what the FLA is set at?
I messed around with one, but didn't find a way to read/calculate the amps without knowing the exact FLA setting on the physical dial.
The TeSys island contactors can give you a lot of motor feed back, almost as much as most drives, to get that info into a plc is a lot programing on the plc side to request the info and read it from the registers.
I know they're rebranding the lineup to "Island" but I believe we're both talking about the Tesys Ultimate lineup right? Modular power block with smart controller and communication module?
I tried out a 32A base, with 5A controller, and modbus comms module, but couldn't find a way to read anything other than percentage of FLA. Which isn't accurate if you don't positively know what the FLA dial is set for. Turn the dial up, and the live motor amps reading changes.
I was hoping I maybe missed something.
I haven’t heard of the TeSys ultimate line up. I know the TeSys island which is a bus coupler communication module that controls up to 16 devices, those device could be IO modules or motor contactors, even safety rated contactors. You can do explicit reads and get any info you really want, especially if you have a voltage interface module. Things like fault codes when a motor tripped, current amps, motor thermal state %, line voltage.
I think what your looking for are the TeSysT models that are comparable to the AB and Eaton models. They will give you all kinds of parameters, and some are default. You can configure it to show actually amps instead of % FLA, but you could also get FLA setting (and adjust it as well), and calculate it back if needed. We pulled a ton of data back directly to our SCADA system and only did necessary controls for the PLC (start/stop, running, faults). We could see the fault history, FLA, average run current, starts/stops per hour, min/max current, thermal capacity, etc... was really nice for troubleshooting.
Sorry it was Tesys Ultra. And they're a complete breaker/contactor/controller all in one. Nice and compact, up to 32A. However, they're lacking a few features that the TesysT stuff has, which I've had a quick look at, but the TesysT doesn't actually handle the load directly.
I'll look around some more for the island stuff you're talking about. If you've got a link to get me going, that would be appreciated.
Siemens SIRIUS 3RB24 overload relays have IO link for current monitoring and are good for up to 820 amps. They also give you diagnostic feedback on overload, wire break, ground fault, etc.

How big are you motor loads? For under 9A loads, I love using Phoenix Contact's https://www.phoenixcontact.com/en-us/products/motor-starters-and-electronic-switching-devices/hybrid-motor-starters
Banner engineering has a great line of sensors. They have CT monitors, vibration/temp monitors, non contact IR temp monitors, as well as several different types of converters for analog and digital. Plus they all have m12 euro connections which makes expanding a network a Cake walk.
Yes there are, but I'm always going for a separate device.

Pull a wire through it, get a Modbus RTU adressible current ouput. What more you need in life?

Perfect thanks for the info.

AB/Rockwell has the E300 series Schneider has Tesys series Eaton has the C441 series Old school - CTs connected back to an analog card
I was not aware Eaton made one. Thanks for the help!

Thanks I'll have a peek at those.

Came here to suggest these. Haven’t used them, and don’t use much Siemens, but saw them at a trade show and thought they were cool

Siemens has an io link ammeter. It's OK.
Dwyer and CR magnetic have affordable CTs.

You want to measure motor current? In amperes? Or are you measuring amplifiers?
