Appendix F. Other Campbell Scientific Products 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 136. 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 CR800 to output continuous, adjustable voltages that may be required for strip charts and variable-control applications. Table 137. Continuous Analog Output (CAO) Modules 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 CR800 to control large voltages. Table 138. Relay Drivers Model Description A21REL-12 Four relays driven by four control ports A6REL-12 Six relays driven by six control ports / manual override LR4 Four-channel latching relay SDM-CD8S Eight-channel dc relay controller SDM-CD16AC 16-channel ac relay controller SDM-CD16S 16-channel dc relay controller SDM-CD16D 16-channel 0 or 5-Vdc output module SW12V One-channel 12-Vdc control circuit F.5 Dataloggers Other Campbell Scientific datalogging devices can be used in networks with the CR800. Data and control signals can pass from device to device with the CR800 acting as a master, peer, or slave. Dataloggers communicate in a network via 541
