This document explains how to connect the SLSC-12201.
Note Before you begin, complete the software and hardware installation
procedures applicable to your application.
Note The guidelines in this document are specific to the SLSC-12201. The other
components in the system might not meet the same safety ratings. Refer to the
documentation of each component in the system to determine the safety and EMC
ratings for the entire system.
Safety Guidelines
Caution Observe all instructions and cautions in the user documentation. Using
the model in a manner not specified can damage the model and compromise the
built-in safety protection. Return damaged models to NI for repair.
Attention Suivez toutes les instructions et respectez toutes les mises en garde de la
documentation utilisateur. L'utilisation d'un modèle de toute autre façon que celle
spécifiée risque de l'endommager et de compromettre la protection de sécurité
intégrée. Renvoyez les modèles endommagés à NI pour réparation.

Isolation
Channel-to-channel None
Channel-to-earth ground None
Caution Do not connect the SLSC-12201 to signals or use for measurements
within Measurement Categories II, III, or IV.
Attention Ne connectez pas le SLSC-12201 à des signaux et ne l'utilisez pas pour
effectuer des mesures dans les catégories de mesure II, III ou IV.
Measurement Category I is for measurements performed on circuits not directly connected to
the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live
electrical supply system that powers equipment. This category is for measurements of voltages
from specially protected secondary circuits. Such voltage measurements include signal levels,
special equipment, limited-energy parts of equipment, circuits powered by regulated lowvoltage sources, and electronics.
Note Measurement Categories CAT I and CAT O are equivalent. These test and
measurement circuits are for other circuits not intended for direct connection to the
MAINS building installations of Measurement Categories CAT II, CAT III, or
CAT IV.

Connecting Digital Devices to the SLSC-12201
The SLSC-12201 has 32 digital input/output channels that allow the direction to be configured
for each channel. The 32 channels are organized into two banks of 16 channels each. Each
bank can be powered from either of the Vsup connections. The banks are further organized
into two ports of eight channels each. In the example shown below, the SLSC-12201 connects
to the PXIe-7821R through the RTI-12301.
Short-Circuit Protection
Digital output channels are protected against short-circuit faults.
8 | ni.com | SLSC-12201 Getting Started Guide
Note The SLSC-12201 supports up to 10 channels in simultaneous short-circuit
fault.
