Connecting User Inputs
The Keysight E1459A Isolated Digital Input/Interrupt module consists of a
component module and a terminal block. User inputs for each channel consists
of a low and a high connection for each channel. The inputs will only detect
signals of a positive polarity. A logical "1" will only be detected if the high
terminal is at a higher potential than the low terminal. It must also meet the drive
requirements for the voltage threshold selected.
For each block of 16 channels an additional active low input and two active low
outputs are available. The table below lists the signal names and the associated
channels.

Figure 7 shows the front panel terminals and pinouts for the module. The cover
to the terminal module is silk-screened to indicate the function of each screw
terminal.
