See Chapter 8 of the
i. LON 100 e3 User’s Guide for instructions to follow when
configuring the
i. LON 100 server to use the pulse inputs it is connected to.
Digital Inputs
The i .LON 100 server has two optically isolated, polarity sensitive digital inputs
that you can use to monitor switch and sensor devices. The supervision of the
inputs is under software control of the
i .LON 100 server and its Digital
Input/Digital Output applications.
The digital input connections are implemented on screw terminals 13 through 16.
Input 2 is connected to terminals 13-14 and Input 1 is connected to terminals 15-
16. The digital inputs are polarity sensitive, and the (+) and (-) connections for
Input 1 and Input 2 are noted adjacent to the terminals. Reversing the polarity
of the digital inputs will cause improper operation of the monitoring circuits and
must be avoided.
Figure 1.10 shows the digital input screw terminal connectors.
