Hello All:
I am in the preliminary design of a system to control various laser safety tri-color beacons utilizing a Koyo CLICK PLC. I have very little recent PLC experience.
The system will support multiple stations looking at various laser and shutter control signals to decode the proper lamp...
Had to replace my water heater timer (again, due to chinesium relays) and went to a different make (DTWH40).
What concerns me is the new unit has terminal blocks as opposed to screw terminals. Unit is rated for 40A resistive load up to 277VAC.
My application is around 30A, was a bit hesitant to...
Does anyone know off-hand of any micro PLC's with isolated digital inputs?
Requirements are minimal:
4 discrete isolated digital inputs (logic high at TTL to 24VDC levels).
4 outputs, common can be shared, relay or sink/source for 24VDC 150mA loads.
Minimal non-volatile memory, I am guessing...
I have a project where we need to heat a small part up for a few seconds in the range of 100-120C. The best approach looks to be a small coil made of a few turns of 18 gauge nichrome wire. Open loop control will probably suffice for this application. Guessing that power needed will be in the...
I'll be travelling off-site from work where my primary power source is 12VDC automotive. Was considering using a few hundred watt non-sinusoidal 12VDC to 120VAC inverter to power the battery chargers for the laptop and camcorder.
However, reading the manuals for the laptop/camcorder, they...
Howdy:
We have a batch process that 'cooks' material in a chamber under high pressure and moderate temperature. The system was built in-house, it uses a few kW of resistive heater bands controlled by a PID unit. Well, the SSR that supplies power to the bands shorted closed, luckily someone was...
Questions and guidance regarding chrome-on-fused silica targets used to calibrate vision systems:
We have a couple of these at our facilities and in order to satisfy ISO requirements, some people internally insist these must be sent out yearly to be ‘calibrated’ (re-certified is probably a...

I'll be doing additional research on my own, but thought I'd post here in case anyone has had similar needs/solutions.
We have an extruder that we'd like to monitor and log data on using data acquisition hardware. The majority of the signals are J and K type thermocouples that are fed into PID...
Hello:
My company is looking to build or buy a specialized multi-axis CNC system for laser-based processing of glass. One potential vendor we are looking at is Rofin-Sinar. Has anyone had experiences with this company or their equipment?
If so, let me know your thoughts.
Thanks

Hello:
I am writing a macro to insert data from one workbook (source) into another workbook comprised of one sheet (target)that is protected.
In code snippet below, I activate my source worksheet, define my copy range (1st With/End With block) and copy it.
Then I open my protected target...
