SebSim Posts: 2 Rating: (0)	Currently, these point is connected to a sensor and there is no 24V across pt 18 & 19. Can I rewire the sensor connected to these 2 points to any 2 points on SM 321 module in the rack?

Check there how to make correct wiring. Just to mention terminal 18 and 19 are reserved. I suggest you don'tconnect to24V from SM321 card. Best regards, Hristo Mihalev
