The IC693MDL646 is a 24-volt DC positive/negative logic input module specifically designed for the GE Fanuc 90-30 series of Programmable Logic Controllers. This module features 16 input points within a single group, all sharing a common power input terminal, and is compatible with a variety of user-supplied input devices, including limit switches, push buttons, and proximity sensors. The module offers flexibility in logic configuration, accommodating both positive and negative logic characteristics. Power for field devices is typically provided by the user or through an isolated +24VDC supply connected to the power supply.

User-friendly LED indicators at the top of the module display the ON/OFF status for each input point, organized into two horizontal rows containing eight green LEDs each. The top row is labeled A1 to A8 (points 1 to 8) while the lower row is labeled B1 to B8 (points 9 to 16). Additionally, an insert placed between the inside and outside surfaces of the hinged door contains the wiring diagram on the inside, with circuit identification located on the outside, featuring a blue color code on the left edge to signify low voltage compatibility.

The IC693MDL646 can be seamlessly installed in any I/O slot of a Series 90-30 PLC system. It operates over an input voltage range of 0 to 30 VDC, requiring an input current of 7 mA, with an on-state voltage range of 11.5 to 30 V and an off-state voltage of 0 to +5V DC. The module ensures reliable operation with an on-state current rating of 3.2 mA minimum and an off-state current rating of 1.1 mA maximum.
