External View of Pressure Clamp Terminal Blocks
The models of pressure clamp terminal blocks are shown in the table above. Though the in-
ternal circuits vary with the number of channels, analog or digital signals or input/output, the
external dimensions and appearance are the same. The following figure shows the terminal
blocks for single and dual-redundant configurations.
