8-Channel Valve-Pressure Controller, with precision Timer
Computerized controller for pinch and fast solenoid valves. Generates
pressure up to 15 PSI and allows to switch solution application with
10ms accuracy (an external pressure source is required for higher
pressure up to 100PSI - see table below). No syringe stands or sources of pressure are required. To make a
functional system add PV-V-ADD valves below (add valves according to
the number of channels required, ships installed in an aluminum box - no electrical noise during switching). Can be used with small delivery
manifold
SVDS1 and
pressure cylinders PC. Comes with wireless remote
control.
The controller opens valves through manual switches, wireless remote or by TTL signals generated by a computer
or other equipment. Other control options include: open valves by analog signal,
and through RS232 port (or USB connection). Compatible with data
acquisition and imaging systems. Optional software to generate solution switching sequences to automate complex
routine protocols is available. Incorporates INHIBIT mode:
to CLOSE channels simultaneously, and CODE mode: to operate by limited number of
digital INPUT signals.
Can be configured to work with external source of pressure to generate higher output pressure (on request only).
Specifications: |
Channels: | 8 |
Output Pressure: | up to 15PSI |
Valves: | DB-9 connectors, 12VDC |
Controls: | Digital, TTL, Analog inputs, RS232 software command,
manual |
Manual Overdrive: | Wireless
remote and manual push buttons, override electronical inputs |
Remote control: | Wireless |
Auto Memory: | Automatically switches to preset active channels
pattern |
Code mode: | Use only 4 TTL inputs to encode all channels |
Close mode: | Inhibits all outputs to the valves, manual and electronical inputs |
Analog outputs: | To monitor pressure, and to switch outflow units CFPS-1U (can be also used to mark your recordings; optional configuration for telegraph output) |
Custom modifications: | Additional features can be added or modified on request |
Dimensions: | 2.5 x 12 x 9 in. |
Power: | 120/240 VAC external power supply |
AUTO
Memory
The controller can operate in Auto Memory mode, when a
set of chosen valves opens automatically at the time the other valves close.
This is useful for automatic switching to control solutions after the test
solution is OFF.
Digital input
Optically isolated inputs for each channel. BNC connector for TTL inputs and DB-9 connector.
CODE Mode
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.
Analog Out
Analog
output to switch outflow automatically, or to use as a mark on your recordings (can be
configured for telegraph output).
INHIBIT Mode
Closes valves
regardless of input.
Negative INPUTs
Optional modification to
use TTL inputs to close channels in response to the time sequence pulses. Used
in certain applications when continuous flow through the channel is required,
with short CLOSED periods.
DIMENSIONS
Size: 2.7 x 12 x 9in.
Includes 120/220VAC external power supply.

The analog output can be used to turn OUTFLOW automatically
Shown is a miniature flow control unit, which can drive solution up to 22ml/min. Specify analog option for automatic outflow when perfusion is turned ON.

Optional accessories: small volume delivery system,
micromanifold,
pressure cylinders,
pressure adapter.
