Servo Controller

VFD To Servo – Motion Controller Card

This is control card which can receive command from any control device, system or PLC. The command may be Pulse – Direction, voltage or current and can control any standard VFD, AC / DC drive for position, speed or torque control. Besides this it can record up to 15 pre-defined positions or indexing data. It can also lock two motors to be operated in fixed ratio like electronic gearing. In a way it provides all controls to run standard induction or AC/DC motor like a servo-controlled motor.

DC Drive

Complete, self-contained, stand-alone servo controller Controls one DC motor, with incremental encoder position feed-back Simultaneous control of position, velocity and torque Output protected against shorted load and over temperature On-board trapezoidal trajectory generator with asymptotic homing mode Programmable PID filter gain characteristics. > 2 KHz update rate. High speed multi-drop RS-232 communications for coordinated control of up to 16 axes Low power: Less than one Watt internal dissipation On board command interpreter with over 50 commands, including fully-integrated support for the general purpose analog and digital I/O lines 32-bit precision for position, velocity, and acceleration registers Programmable limits for allowable error Programmable position break points Stored program operation Dual limit switch and reference switch support Eight analog inputs, 0-5V, 8 bit resolution One analog output, 0-5V, 8 bit resolution, 2 mA Eighteen general purpose I/O signals (includes nine analog I/O)

Programmable Pressure Switch

Programmable Pressure Switch With Transducer

This is a digital pressure switch which can trigger relay functions on certain pressure. it is fully programmable and can work in multiple modes.

The display can be configured to give different outputs.

It has a dual relay setup and both relays can be controlled separately as required.
