card и board

[linguanario]

Здравствуйте! Помогите, пожалуйста, разобраться с терминами card и board. Речь идет о датчике текущего положения (Current Position Transmitter – CPT).

The potentiometer is used for the actuator signal feedback. It reads a resistance value which

corresponds with the current position of the actuator and transfers it to the CPT card.

И еще тот же термин с пропорциональным регулятором  PCU :

The factory settings of the PCU card are normally set according to the customer requirements at the time of order.

И про настройку нуля и шкалы:

When the actuator is in the fully closed position, adjust the ZERO close setting on the CPT board until an output value of 4mA is achieved.

When the actuator is in the fully open position, adjust the SPAN open setting on the CPT board until a reading of 20mA is achieved.

Заранее спасибо.
