1.16 DI-1: 12-24 Vo lt AC o r DC In p u t, 16 P o in t
The DI-1 provides 16 input points in one group with common power input terminals. This input module
is designed to have either positive or negative logic characteristics in the DC input mode. Input
characteristics are compatible with a wide range of user-supplied input devices, such as: push
buttons, limit switches, and electronic proximity switches. Current into an input point results in a logic 1
in the input status table (#DI). The digital inputs are powered using an external power supply (the
module does not provide field power).
LED indicators that provide the ON/OFF status of each point are located at the top of the module. This
LED block has four vertical columns with four red LEDs in each column, the left two columns labelled
A1 through 8 (points 1 through 8) and the right two columns labelled B1 through 8 (points 9 through
16). An insert goes between the inside and outside surface of the hinged door. The surface towards
the inside of the module (when the hinged door is closed) has circuit wiring information, and circuit
identification information can be recorded on the outside surface. The outside left edge of the insert is
color-coded blue to indicate a low-voltage module. This module can be installed in any I/O slot of a 3,
4, 6 or 12 slot backplane system.
