I am looking for some advice and I hope this is the place. I fairly new to PLC's but I have been working with them for a year and have never had this problem.
I am a teacher and our school decorates a shelter at a park each year. This year we thought we would be smart and use a PLC to flash some lights and run some motors.
I have a set up that uses the Micrologix 1500 PLC with 9 Relays. Relays 0-3 are Omaron with 110V trigger Relays 4-8 are Omaron with 24v triggers. Relays 0-3 work fine but 24v relays do not. When I run them through the PLC it acts like it shorts the 24v power supply out. When I check with a multi-meter not hooked to any of the relays the PLC output shows 24v. Any ideas. I keep thinking it is a wire issue but I have checked and rechecked.
