2-channel analog input. Resistance measurement from 10 to 5000 Ohms. The analog input module allows for the direct connection of resistors for resistance measurement in the range of 10 Ohms to 5 kOhms. The connection can be made using 2-wire or 3-wire technology. The module handles linearization across the entire temperature range. A short circuit or interruption of the sensor line, as well as an out-of-range condition, are indicated by a red error LED. The green LED indicates operational readiness and trouble-free communication with the bus coupler. The shield connection is directly routed to the mounting rail.
