Fanuc IC693MDL654 PLC

The 5/12 volt DC (TTL) Positive/Negative Logic Input module for the Series 90-30 Programmable Logic Controller provides 32 discrete TTL voltage threshold input points. The inputs are arranged in four isolated groups of eight (A1 - A8, B1 - B8, C1 - C8, and D1 - D8); each group has its own common. The inputs are positive or negative logic inputs and will operate at levels up to 15V. To be compatible with TTL outputs, the negative logic configuration should be used as shown in the following diagram.

A single, regulated +5V supply (current limited to approximately 150 mA) is available through the I/O connectors on the front of the module. This supply is generated on the module and is isolated from the backplane. Its power input comes from the +5V logic supply on the PLC backplane. By installing jumpers on the appropriate pins on the I/O connector, you can choose to power the inputs from this internal supply instead of powering them with an external user provided supply. If this internal supply is used to power the inputs, additional loading will be placed on the PLC’s +5V power supply. Backplane isolation between the field side and logic side is provided by opto-couplers on the module. There are no special fault or alarm diagnostics reported. LED indicators (labeled A1 - A8, B1 - B8, C1 - C8, D1 - D8) at the top of the module provide the ON/OFF status of each input point.

This module is configured as a 32-point input type and uses 32 bits of discrete %I input data. Current into an input point results in a logic 1 in the input status table. This module can be installed in any I/O slot of a 5 or 10-slot baseplate in a Series 90-30 PLC system.
