SLSC-1310 32Ch Isolated Input Card

The SLSC-1310 32Ch Isolated Input Card is an isolated digital input interface for NI-SLSC. This card provides 32 optically isolated digital inputs. SLSC-1310 combines high-density IO with high isolation voltages and a wide input voltage range. It allows you to break ground loops and protect your system from high-voltage spikes, but also to connect high voltage signals to standard logic level acquisition devices. The channel-to-channel isolation allows you to connect signals from different DUTs to a single acquisition system without compromises.

The digital inputs feature a wide supply voltage range and can be used with a variety of signal levels, including 12V and 28V discrete signals.

The high-speed, high-sensitivity optoisolators allow reliable input detection with an input current as low as 0.6mA. To protect the optoisolators, each input contains a current limiting circuit which limits the input current to 6mA over the entire input voltage range.

With a maximum voltage between channels and between channel and chassis of 100Vdc, SLSC-1310 allows you to connect multiple DUTs operating at most usual logic levels to a single data acquisition system.
