EMERSON IC693MDL655 24 Volt DC Positive/Negative Logic Input Module

The 24 volt DC Positive/Negative Logic Input module for the Series 90-30 Programmable Logic Controller provides 32 discrete 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 30V. Backplane isolation between the field side and logic side is provided by opto-couplers on the module. Isolation is also provided between the four groups of inputs on the module, however each group of eight inputs is referenced to the same user common connection. 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. Power to operate field devices can be supplied by the user, or from the isolated +24 VDC supply available at the module’s I/O connectors. This module can be installed in any I/O slot of a 5 or 10-slot baseplate in a Series 90-30 PLC system.
