ValveLinks can switch 12V DC solenoid valves open and closed in one millisecond using full power, then hold-in at 1/2 power to prevent thermal transfer to your solutions. Low noise circuitry minimizes recording artifacts in electrophysiology. Both ValveLinks and ValveBanks are designed for use with pClamp, Pulse, AxoGraph, et al. All AutoMate products include a one-year limited warranty covering both parts and labor (see manual for more details).
ValveGuard technology detects bad valves to prevent damage to your ValveLink and easily observe problem valves. Front-panel LEDs are dark for broken or disconnected valves, or blink for short-circuited valves. Automatic networking lets you connect up to eight ValveLinks to a USB hub and PC to create a single 64-channel controller. One analog input can control eight valves: zero volts closes all valves, and each half-volt increment opens the next valve (i.e. 3 volts opens valve six). Analog event marker allows you to record all valve activity.
ValveLinks are less expensive than AutoMates ValveBank controllers and include manual pushbuttons, digital/TTL, analog and USB inputs to control valves. They are designed for easy control by your data acquisition software. The ValveLink is the controller of choice for dose response work at pharmaceutical companies and the NIH. Its sophisticated design allows control of sixteen valves with only four digital outputs from pCLAMP. A spill sensor stops all valves when a leak is detected to protect your microscope and table. All LEDs blink until you press a button to continue. ValveLinks can now power individual valves up to 1 amp (12 watts), and a total of 2 amps for all valves open simultaneously.

| "Our lab has been using ValveLink controllers for years with good, reliable results. The new ValveLink8.2 is even smaller and faster than its predecessor. It also looks cool and the buttons feel nicer than the previous version. I use it manually or programmed by outputs from my stimulator. I haven't observed any noise from the valve system on my electrophysiology rig." |
