F.4 Control Output Modules
F.4.1 Digital I/O (Control Port) Expansion
Digital I/O expansion modules expand the number of channels for reading or
outputting or 5-Vdc logic signals.
Table 143. Digital I/O Expansion Modules
Model Description
SDM-IO16 16-channel I/O expansion module
F.4.2 Continuous Analog Output (CAO) Modules
CAO modules enable the CR3000 to output continuous, adjustable voltages that
may be required for strip charts and variable-control applications.The CR3000 has
integral CAO channels. Expansion modules are required only if additional
capacity is needed.

Model Description
SDM-AO4A Four-channel, continuous analog voltage output
SDM-CVO4
Four-channel, continuous voltage and current analog
output
F.4.3 Relay Drivers
Relay drivers enable the CR3000 to control large voltages.
