Hello everyone,
My company has an old line for building DC motors. Many machines are from the early 90's and some requests for safety improvements have been made. I'm working with and old coil machine from 1990 in which the guard doors are protected by Honeywell Micro Switch limit switches. There are 4 limit switches wired in series to a single 24VDC input of an Omron Sysmac C60 K. I do not have the software to program this controller, nor is there any room in the enclosure to add safety relays etc.
I'm not required to bring these machines up to code, management just wants to replace any interlocks that can be so easily overcome. I was wondering if there are any devices that could replace these limit switches as is. I.e, requires no power source or very low amperage 24V, no OSSD, uses physical contacts?
We would normally use SensaGuard contactless sensors or Omron D4SL guard locking switches for something like this but with the dated hardware and limited/non-existent cabinet space, I'm looking for a one-for-one replacement. If I can't find something, I'm not sure what to do outside of upgrading to Compact w/ safety relays or GuardLogix.
Thanks in advance!
