3.1 Pin assignment of I/O module AI 16xTC/8xRTD 2-/3-/4-wire HA
General pin assignment
The measurement types for resistance measurement (incl. PTC) and resistance thermal
measurement are only possible on Channels 8...15. If a measurement type with 3-wire or 4-
wire connection is configured for channel x (x = 8...15), then channel y (y = x+8) must be
disabled.
