The Keithley 7707 is a 40-channel digital I/O module designed for use with Keithley Series 7000 switching mainframes, such as the Model 2700, 2701, and 2750. It provides 40 digital input/output channels, which can be configured as either inputs or outputs in groups of eight. The module is ideal for controlling external devices, monitoring digital signals, or interfacing with relays and other logic-level circuits. The 7707 supports TTL-compatible logic levels and offers high-speed digital switching capabilities, making it suitable for automated test systems and data acquisition applications. The module is installed directly into the mainframe and is controlled via the mainframes user interface or remote commands.
