analog card is that where we have to measure the temperature
of RTD and Thermocouple, where as digital card is used as
that check the condition of the motor is in on condition or
off condition, in analog card we have two voltages like
(0-10v) and (4-20mA) and in this card we have a switch
setting for the reason that we want o/p in mA or V in many
case, in the case of analog card we have a single i/o card
with it self but in case of digital card we have a i/o card
is separate, analog card is a measuring value device but in
case of digital card its o/p is either 0 or 1, and digital
card o/p is turned on due to relays.
