Comparing The 7080 And 7080D - Measurement Computing CB-7080 User Manual

Introduction
CB-7000 is a family of network data acquisition and control modules. They provide A/D, D/A, DI/O,
Timing/Counting and other functions. These modules can be remote controlled by a set of commands.
The common features of the CB-7080 and CB-7080D include:
Two independent 32-bit counters, counter 0 and counter 1.
Input signals can be isolated or non-isolated.
Programmable digital filter for isolated and non-isolated input.
External gate control for isolated and non-isolated input.
Programmable threshold value for non-isolated input.
Programmable alarm output.
Input frequency measurement up to 100 kHz.
The CB-7080D module identical to the CB-7080 with a 5-digit LED display added. The LEDs can display the
counter value and input signal frequency without PC control.
