1.19 DI-4: 240 Vo lt AC In p u t, 16 P o in t
The DI-4 240 volt AC input module provides 16 input points with two common power input terminals.
The input circuits are reactive (resistor/capacitor) inputs. Current into an input point results in a logic 1
in the input status table (#DI). Input characteristics are compatible with a wide range of user-supplied
input devices, such as: push buttons, limit switches and electronic proximity switches. Power to
operate the field devices must be supplied by the user. This module requires an AC power source; it
cannot be used with a DC power source.
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 red to indicate a high-voltage module. This module can be installed in any I/O slot of a 4,
6 or 12 slot backplane system.
