The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: Agilent - Model: L7231 - Condition: Used and in Excellent Condition - Price: $250.00 USD - Availability: In stock, 1 available - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 3.5 lb, estimated - Shipping dimensions: 8X8X3 in, estimated ## Categories - Lab & Analytical > Lab Parts (primary) ## Details Part Numbers: L7230, L7230301, L7231 ## Function Eight-channel electronics assembly that supplies and times drive signals to electrovalves used in analytical instrumentation, enabling rapid, synchronized actuation and sequencing of gas-flow paths. Provides high-current, low-impedance outputs to energize solenoids with defined voltage and polarity, with programmable pulse width and on/off timing, and common enable control. Interfaces to instrument controller via TTL/CMOS-level inputs and yields status indicators or fault protections. Designed for precise valve actuation in multiport routing schemes, supporting concurrent or staged valve operation with protective features for coil flyback and supply stability. ## Images - - - -
