1.17 DI-2: 48 Vo lt AC o r DC In p u t, 16 P o in t
The DI-2 48 volt DC input module provides 16 input points in one group with a common power input
terminal. This input module is designed to have either positive or negative logic characteristics in the
DC input mode. This input module is designed to function with DC user inputs. 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). Power to operate the field devices must be supplied by the user.
LED indicators which 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 4, 6 or 12 slot backplane system.
