National Instruments SET-1310 Digital Input Interface Card

The SET-1310 is a digital input interface card that is used with National Instruments Switch, Load, and Signal Conditioning (NI-SLSC) systems. This interface card provides 32 channels of optically separated digital inputs, which is essential for maintaining safe and dependable operations in industrial settings where high voltage and fluctuating signal levels are regular occurrences.

The SET-1310 is adaptable for a range of industrial applications since each channel can handle input voltages between 3.3V and 60V. Due to the channel's separation from one another, signals from many devices under test (DUTs) can be connected to a single data acquisition system without running the danger of ground loop problems or electrical interference.

One significant feature of the SET-1310 is the extensive protective measures in place. Every input on the card has a current-limiting circuit installed, which limits input current to 6 mA throughout the whole input voltage range. This safety process is essential to prevent any potential damage to the optoisolators from current spikes.

The SET-1310 supports many different safety and electromagnetic compatibility (EMC) standards to ensure it does not contribute to electrical noise and interference in its operating environment. It is designed to be used with shielded cables, with a recommendation that the cable length to any connector (specifically J1 and J2) should not exceed 3 meters to maintain optimal EMC performance.

The SET-1310's dimensions are 144.32 x 30.48 x 302 mm, which fits the standard SLSC card size and guarantees compatibility with the current SLSC chassis. Two female DB-44 high-density D-Sub connections with a 4-40 UNC screw lock are utilized on the front panel. These connectors offer the secure connection necessary for industrial applications.

Additionally, the environmental requirements for the SET-1310's operation are very specific. The instrument can tolerate non-condensing humidity levels of 10% to 90% and performs well in temperatures between 0°C and 85°C. The SET-1310 can operate dependably in a variety of environmental conditions, from standard industrial floors to more controlled laboratory settings.

The SET-1310 is designed to satisfy the needs of high-density digital input applications. It provides strong isolation, a wide range of voltage management options, and compliance with strict safety and EMC regulations.
