The National Instruments SLSC-12202 (Part Number: 787244-01) is a robust 60 V Digital I/O Module designed for versatile applications in industrial automation, particularly in environments requiring interaction with automotive and aerospace signal levels. This module features 32 bidirectional digital channels, allowing each channel to be configured independently as either an input or output to accommodate diverse operational needs. As an output, each channel can deliver up to 150 mA of current, supporting sourcing, sinking, and push-pull modes. Furthermore, to enhance adaptability, the SLSC-12202 allows for the configuration of two distinct output thresholds using up to two external reference voltages, facilitating precise control in a variety of scenarios.

For input configurations, the channels are capable of both sourcing and sinking modes, with options to implement dual logic transition thresholds per channel to enable customized signal recognition. This dual threshold capability ensures accurate signal processing essential for complex digital systems. The 32 channels are organized into two banks of 16, each powered by separate Vsup connectors, and further divided into two ports of eight channels for optimized power distribution and management.

Additionally, the SLSC-12202 incorporates robust protective features to guarantee reliable operation under challenging conditions. Hiccup-mode protection safeguards against short-circuit failures by disconnecting the affected channel while permitting an automatic attempt to re-enable it after a brief interval. If the short-circuit condition persists, the module continues to operate in hiccup protection mode to maintain overall system integrity.
