Keithley 7707 – 32-channel Digital I/O Module
$969.00
In Stock
The Keithley 7707 digital interface card expands automated testing racks by blending a 32-channel digital I/O network with a 10-channel multiplexer system. This dual-purpose acquisition board drives external logic circuit relays while measuring analog voltage lines cleanly. It features high sink currents up to 300mA to actuate heavy industrial components.
