|RS-232 interface cable|
|Multi-drop cables to control multiple actuators|
One actuator can be used on any selector, from 2 to 96 positions - you tell the actuator how many stops to make through its 360° of rotation. So you can stock only one type of actuator even if you have 4, 6, 8, 10, 12, and 16 position valves. Valve position memory is maintained even in the event of a power failure.
The direction reversal feature means that if a 6 position stream selection valve is on stream 1 and you select stream 6, you have the option of stepping "backwards" to stream 6 instead of passing through 2, 3, 4, and 5.
The RS-232 input offers various commands like position access, direction control, shortest route, etc. (The RS-232 cable must be ordered separately.)
Some valves are harder or easier than others to rotate, so we offer two microelectric models - high speed and high torque. WHICH MODEL DO I NEED?

RS-232 interface cable
An RS-232 cable is required for controlling an actuator from a computer serial port.
|RS-232 interface cable||I-22697|
Multi-drop cables permit a single serial port to control multiple microelectric two position and multiposition actuators. Multi-drop cables have one female DB9 connector and 2 to 8 male DB9 connectors and are approximately 6" long.
Note: An RS-232 interface cable (I-22697) is required for each actuator controlled serially.

Plug-and-play cables will allow a direct connection and control between a specific instrument and a multiposition microelectric actuator. Contact technical support for cables for other instruments.
