The CR10 was a predecessor of the CR10X. The CR10X was eventually replaced with the CR1000. The CR10 consisted of a CR10M Measurement and Control Module and a CR10WP Wiring Panel.
The CR10 had 12 single-ended (six differential) analog input channels, three switched excitation outputs, eight input/output control ports, two pulse counting channels, and a serial I/O port. It provided sensor measurement, timekeeping, data reduction, data/program storage and control functions. Up to 29,908 data points were stored in it's internal memory.
CR10s manufactured after 1 December 1993 (SN>19273) contained an internal jumper that supported use of 2 or 4 kbytes program memory (appropriate PROM also required).
CR10 peripherals such as the CR10KD and CR10TCR, as well as sensors and data retrieval peripherals, were added to complete the system.
