The IC693MDL654G operates as a 32-point TTL input module within the GE Series 90-30 PLC platform. This unit accepts 5 to 12 VDC signals across four isolated groups of eight channels each. Consequently, system integrators deploy this module for high-speed data acquisition from sensors and switches.
Input Characteristics and Signal Handling
Each input point recognizes logic levels between 4.2 and 15 VDC as the ON state. The module draws 3.0 mA per point at 5 VDC and 8.5 mA at 12 VDC. Furthermore, the design accommodates either positive or negative logic configurations through simple jumper settings. A 1 ms maximum response time ensures rapid signal detection for time-critical control loops.

Physical Design and Connectors
The IC693MDL654G occupies a single slot in any Series 90-30 baseplate. Two 24-pin male connectors on the front panel provide field wiring access. The right connector serves groups A and B, while the left connector interfaces with groups C and D. Additionally, LED indicators labeled A1 through D8 display real-time ON/OFF status for every point.
Internal Power Supply Feature
The module generates a regulated +5 VDC supply capable of sourcing 150 mA. Operators can power field devices from this internal source by installing jumpers on the connector pins. However, this configuration increases loading on the PLC backplane power supply. Therefore, engineers typically use an external supply for larger input device loads.
