CR723T 5 Volt Analog Input Card with RTD

Overview

The CR723T card provides 14 differential or 28 single-ended inputs. The CR723T also contains an RTD that provides a reference junction for thermocouple measurements that is accurate to ±0.1°C over the range of -40° to +60°C.

Each CR723T is placed in an open slot on the CR7 720 or CR7 720XL I/O module (the CR7 720 can accommodate up to 7 cards; the CR7 720XL can hold up to 14). More than one CR723T card can be used in one I/O module.
