Programmable 16-Channel Valve Controller PC-16

This is a computerized controller with programmable timers to deliver liquid application sequences with precise timing even during manual operation. The controller can drive any solenoid  with a wireless remote control, digital (TTL) inputs, or software commands. To make a functional system, simply add valves below. Syringe holders and tubing might be required. The 16-channel controller is included with every 8/16-channel perfusion system. Built-in 0-15PSI pressure controller-pump (PC-16P model only). Compatible with data acquisition and imaging systems: LabView, MatLab, pClamp, IPlab, PatchMaster, Metamorph, MetaFluor and others.

Miniature Solenoid Valves, 1.5ms switch time
These fast valves can be used for single cell/small sample superfusion, or to switch solutions in microfluidics setups. They do not create disturbance due to minimal inside working volume. Provide barbed connection for 0.042in. I.D. soft tubing. The set of eight (x8) valves are mounted in a small aluminum box 125x25x50mm, which comes with 1ft. long mounting 0.5in. rods and x-blocks. We also provide solenoid valves for larger volume perfusion and pinch valves for easy maintenance.

AUTO Memory
The controller can store up to 16-step sequence (32-steps if wash between channels is used) to activate multiple channels in programmed order or a continuous loop. This is useful for automatic switching of liquid media in sequence, including automatic "wash" between "test" solutions applications in sequence. The sequence is programmed using the touch screen of the controller.

Digital input
Optically isolated inputs for each channel. BNC connector for TTL inputs and DB-9 connector.

The controller has an options for valves control by channel encoding using only 2-4 digital inputs, in case if a limited number of digital outputs is available in your system.

Analog Input
You can also use analog signal input to switch the channels by changing the voltage (0.5V increment).

USB/RS232 Input
The RS232 port allows automation of solution switching and integration with imaging systems.

5V TTL signal output to switch inflow/outflow pump automatically.

Closes valves regardless of input.
