Solid-state relays and power sensing modules allow you to interface your PC to real-world AC and DC power lines. our "CY" line of modules and mounting boards feature only genuine Opto 22 products, the leader in the field, and the name that is synonymous with solid-state relays. Mounting panels feature status LEDs and a 5-amp fuse on each channel to prevent short circuits. CY Series modules are perfect for our CY PB, CYSSR, and other Opto 22-compatible I/O module mounting panels.
Output (or power) relays use a low-level output signal from a DIO module to open or close an output power circuit that is typically rated at hundreds of volts and 1 to 5 amps. In the CyberResearch numbering system, OAC relays are AC Output relays and ODC relays are DC output relays.
Conversely, an input (or power-sensing) relay uses power-level voltages to open or close a logic-level connection to an input line on a DIO module. CyberResearch IAC relays are AC input models and IDC relays are DC input models.
