With the exception of the MC-MIO-16, all MIO boards are capable of
powering up to four AMUX-64T boards. The MC-MIO-16 has enough
remaining power to start up to two AMUX-64T boards. Each AMUX-64T
board typically draws 78 mA. Table 2-4 shows the amount of power the
MIO boards can supply to the AMUX-64T.
Temperature Sensor
Table 2-2 shows the positions for jumper W1.
The AMUX-64T is equipped with an onboard temperature sensor for use
with thermocouple cold-junction compensation. This sensor is a National
Semiconductor LM-35CZ that provides a voltage output of 10 m V/°C,
with an accuracy of ±1 °C. The sensor is jumper-selected on differential
input channel 0.
