When it comes to the ALG233 analog input module, can it be configured to provide 24vdc (4-20ma loop) to field instruments while also accepting field instruments that have their own loop power? The manual (GFK-2718AI) includes two scenarios where the module either supplies 24vdc or the field instrument supplies its own power. I am working with an instrument that outputs 15vdc at 4-20ma.
While I can't give a definitive answer, the source of power for your device should not significantly impact its performance. In my experience with ALG233 devices utilizing 4-20mA, control devices usually receive +/-15 or 24VDC either from the main panel DC bus or from a separate local DC power supply, connected to the MCP common in some instances. It is important to use common sense and consider practicality when making these choices.
Ken, I appreciate your response. Is there a convenient time for us to have a discussion regarding my issue? I believe providing more context will help address my problem effectively.
I would connect the grounds of the two DC power supplies.
JCAI# expressed gratitude to Ken for his response and inquired about the possibility of further discussion to provide more details regarding their problem. Ken confirmed the availability for a conversation and mentioned that a private message has been sent.
Yes, the ALG233 analog input module does have that flexibility. It can be configured to supply 24vdc to field instruments while accepting field instruments that have their own power source. In your case, the instrument that outputs 15vdc at 4-20ma with its own power source can still be read by the module. You only need to ensure that the wiring is configured in line with the "Field power supply" scenario in the GFK-2718AI manual. You're working with pretty flexible equipment here, so it can be fine-tuned to meet your specific requirements.
Great question! The ALG233 module can indeed be configured to accommodate different power scenarios, but it's really important to ensure that the configuration matches your specific application. If you’re dealing with an instrument that outputs 15VDC, you should verify whether it's compatible with the input range of the module. Just remember, if you’re using the module to supply 24VDC, make sure that it doesn’t over-volt your instrument. Conversely, if the instrument has its own power supply, the module should be set up to accept that without any issues. Always double-check the setup in the manual to avoid any conflicts in voltage supply!
