The IC693MDL634 is a 24-volt DC Positive/Negative Logic Input Module designed for the GE Fanuc Series 90-30 Programmable Logic Controller. This module features a single group comprising eight input points connected to a common power input terminal, facilitating both positive and negative logic configurations. It is compatible with a wide range of user-supplied input devices, including electronic proximity switches, pushbuttons, and limit switches. When an input point is activated, it generates a logic 1 in the input status table (%I). Users have the option to supply power to operate field devices directly or utilize an isolated +24 VDC output to power a limited number of DC inputs. The input voltage range of the IC693MDL634 extends from 0 to +30 volts DC, with a typical input current of 7 mA at the rated voltage. The input characteristics include an on-state voltage of 11.5 to 30 volts DC and an off-state voltage of 0 to +5 volts DC, with a minimum on-state current of 3.2 mA and a maximum off-state current of 1.1 mA. Conveniently, the module is equipped with LED indicators for each input point, arranged in two horizontal rows of eight green LEDs, allowing for easy visual status monitoring. The module also features a hinged door with an internal insert that includes blue coloring on the left edge, indicating that it is a low-voltage unit. Circuit wiring details are printed on the inside, while user-identifiable information can be documented on the exterior surface. The IC693MDL634 is compatible for installation in any I/O slot of a 5 or 10-slot baseplate within the Series 90-30 PLC system.
