PCI-1100 Series Digital Opto-Isolator BlocksPCI-1100 Series Digital Opto-Isolator Blocks
The PCI-1100 Series are digital, optically isolated, signal conditioning blocks. A separate opto-
block is used for each channel, allowing complete I/O flexibility.
The twelve different opto-blocks are divided into two groups: standard and slim-line.
Both standard and slim-line models can be used on EDAS-1011T-1 Panels.
• Only standard models (PCI-1101 through PCI-1106) can be used with the PCI-20018T-1 and
PCI-20048T-1 termination panels.
• Only slimline models, PCI-1107 through PCI-1112, can be used with 3U sized termination
panels (PCI-20324T-1 and PCI-20326T-1).
Summary of Features
• All input models accept both AC and DC voltages.
• Each provides a TTL output to drive a standard digital input.
• Different models are provided for AC and DC outputs.
• Units convert TTL outputs from the data acquisition system to switch higher voltage and
current loads.
• DC output devices present an open collector NPN transistor to the load.
• AC output units contain zero crossing circuitry and switch their loads with triacs.
• All models provide 4000 V isolation input to output.
Various combinations of the available opto-blocks can be intermixed on one termination panel.
Each contiguous group of eight channels must contain only input or output opto-blocks since the
digital channels on the Digital I/O UDAS are programmable as inputs or outputs in byte-size (8
bits) units.
