EMERSON IC693MDL241 16-Point 24 VAC/DC Positive/Negative Logic Input Module

The 24 volt AC/DC Positive/Negative Input module for the Series 90-30 Programmable Logic Controller 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 AC or DC user inputs. Input characteristics are compatible with a wide range of user-supplied input devices, such as pushbuttons, limit switches, and electronic proximity switches. Current into an input point results in a logic 1 in the input status table (%I). Power to operate the field devices can be supplied by the user, or the Isolated +24 VDC output on the power supply (bottom two power supply terminals) can be used to power a limited number of DC inputs. LED indicators which provide the ON/OFF status of each point are located at the top of the module. This LED block has two horizontal rows with eight green LEDs in each row; the top row labeled A1 through 8 (points 1 through 8) and the bottom row labeled 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 5 or 10-slot baseplate in a Series 90-30 PLC system.
