1-Channel Digital Input Module for SCC—The SCC-DI01 is an optically isolated digital input module for sensing digital signals. The SCC-DI01 can sense both AC and DC signals and has a status LED for visual verification of the module input status. The SCC-DI01 fits in any SC-2345 socket J9 through J16. When you install an SCC-DI01 in one of these sockets, the digital signal is automatically routed to a DIO line of the multifunction DAQ device. Because you can configure multifunction DAQ devices for input or output on a line-by-line basis, you can have up to eight SCC-DI modules per carrier.
