Analog Pod
OP-8AT
Overview
CAN/high-speed analog measurement expansion set A pod that can be used by attaching to the SB-C2AN to perform high-precision analog measurement and temperature measurement using thermocouples.
* This pod is different from the analog pod (OP-8AH) included with SB-C2AN.

*1: Accuracy at ambient temperature of 18 to 28°C and after 20 minutes after power on, does not include thermocouple error.
If the above ambient temperature range is exceeded, add 1/20 of each error value for every 1°C.
If the above ambient temperature range is exceeded, add 1/20 of each error value for every 1°C.
*2: In environments where a part of the measurement pod is locally heated or cooled, cold junction compensation accuracy cannot be guaranteed.
