This logic input module accepts digital signals from field sensors and pushbuttons for processing. It provides reliable status detection for discrete control applications. The IC693MDL655 offers 32 input points in a compact single-slot format.
Core Input Specifications
The module accepts 24 V DC sourcing or sinking inputs from various field devices. Each input channel delivers optical isolation of 1500 V RMS for noise immunity. Furthermore, the unit operates with an input current of 7 mA per point at nominal voltage. It features a response time of less than 2 milliseconds for rapid signal detection. The module also includes built-in LED indicators for real-time input status monitoring.
Connectivity and Diagnostic Features
The front panel houses a 40-pin ribbon connector for direct field wiring terminations. This connector supports quick attachment to external terminal blocks for easy installation. Additionally, the IC693MDL655 provides a second 20-pin connector for expansion wiring. A bank of 32 green LEDs displays the active or inactive state of each input. Engineers can configure the module for either sink or source operation using onboard jumpers.
Energy Storage and Input Protection
An integrated RC snubber network suppresses voltage transients on each input channel. This protection circuit handles surges up to 2000 V for reliable field interfacing. Furthermore, the IC693MDL655 includes reverse polarity protection on all input terminals. The module incorporates a self-resetting fuse that trips during overcurrent conditions. It draws a maximum current of 100 mA from the backplane supply.
Mechanical Specifications and Environmental Ratings
The PCB measures 22.5 x 13.5 x 4.0 centimeters and weighs approximately 500 grams. Its rugged construction uses high-grade FR-4 material for thermal stability. The board mounts easily into GE Series 90-30 rack systems. Moreover, the IC693MDL655 operates reliably across temperatures from 0°C to +60°C.
