The Smart E Tech SET-1310 Digital Input Interface Card is engineered for integration with National Instruments Switch, Load, and Signal Conditioning (NI-SLSC) systems, offering robust performance suitable for industrial applications. This interface card features 32 channels of optically isolated digital inputs, crucial for ensuring safe operations in environments characterized by high voltage and variable signal levels. Each channel is capable of managing input voltages ranging from 3.3V to 60V, allowing connections from multiple devices under test (DUTs) while minimizing the risk of ground loop issues or electrical interference. Enhanced safety is a core design principle of the SET-1310; it incorporates current-limiting circuits on each input, restricting the maximum input current to 6 mA across the entire voltage range to protect the optoisolators against current spikes.

Moreover, the SET-1310 meets stringent safety and electromagnetic compatibility (EMC) standards, ensuring minimal contribution to electrical noise within its operational environment. The interface card is optimized for use with shielded cables, with a recommended maximum cable length of 3 meters to connectors J1 and J2 to maintain EMC performance. With dimensions of 144.32 mm x 30.48 mm x 302 mm, the SET-1310 conforms to the standard SLSC card size, guaranteeing compatibility with existing SLSC chassis. The front panel is equipped with two female DB-44 high-density D-Sub connectors with a 4-40 UNC screw lock for secure industrial connections.

The SET-1310 operates effectively in a wide range of environmental conditions, supporting non-condensing humidity levels between 10% and 90% and functioning within a temperature range of 0°C to 85°C. This versatility allows it to perform reliably on standard industrial floors as well as in controlled laboratory environments. Designed specifically for high-density digital input applications, the SET-1310 excels in delivering strong isolation, extensive voltage management capabilities, and compliance with rigorous safety and EMC regulations, making it an essential component for modern industrial automation systems.
