B.1.3 Isolator Blocks
PCI-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.
