Troubleshooting an issue in which a 1756-IF8 AI card is usually working fine reading a ~12mA current loop from a device. When firing a relay from an adjacent relay output card, the current loop drops to 0 mA for about a second.
This seems to be caused by something in the IF8 card as the current loop does not change when bypassing the card/PLC. Got another card on order to test that theory, but does that problem sound familiar to anyone?
The IF8 card is configured as 8 single-ended 0-20mA inputs. Thanks for any info.
