SCB-100 100-Pin Shielded
Connector Block
This guide describes how to connect and use the SCB-100 100-pin shielded connector block with
100-pin data acquisition (DAQ) products.
Introduction
The SCB-100 100-pin shielded connector block is a shielded board with 100 screw terminals that
connect to the AT-MIO-64E-3, AT-MIO-16DE-10, or other products using the 0.050 series
shielded D type I/O connector.
The terminal block has 100 screw terminals for easy connection to signal wires. A cold-junction
compensation temperature sensor is included for use with thermocouples. When the SCB-100
100-pin shielded connector block is used with other 100-pin products, bypass the accessories (the
cold junction compensation temperature sensor and the signal accessory power LED) using the
six switches, leaving a generic 100-screw terminal connector block. The SCB-100 also has a
strain-relief bar for securing signal wires or cables.
