Part Number: IC693MDL654

The IC693MDL654 is a 5/12 volt DC positive/negative logic input module designed for use with the Series 90-30 Programmable Logic Controller. This module features 32 discrete TTL voltage threshold input points organized into four groups of eight (A1 - A8, B1 - B8, C1 - C8, and D1 - D8), accommodating input voltages ranging from 0 to 15 volts DC. Each input is capable of accepting either positive or negative logic. The module generates a +5V supply internally, which can be separated from the PLC backplane, allowing users the option to power inputs via the internal supply or an external source, depending on jumper configurations on the I/O connector. Internal powering will increase the load on the PLC’s +5V supply. The IC693MDL654 incorporates opto-couplers that provide significant backplane isolation—1500 volts between the field side and logic side, and 250 volts between the four groups of inputs. It operates with an internal power consumption of 195 mA from the +5V bus on the backplane and features LED indicators for each input point to visually indicate operational status. With a typical ON current of 3.0 mA at 5 VDC and 8.5 mA at 12 VDC, this module effectively converts input signals into a corresponding logic 1 within the input status table. The module includes two male 24-pin connectors for field wiring, facilitating connections to external devices. The IC693MDL654 is ideally suited for installations on a 5 or 10-slot baseplate within a Series 90-30 PLC system.
