The VP100 valve positioner is an autotamtic or manually controlled electronic valve positioner which operates within the motor feedback circuit. When it automtaic mode it tracks the input signal or in manual mode where the actuator can be driven to any desired position.

FEATURES

  • Auto/manual control
  • Manual ramp up and ramp down
  • 120 or 240VAC 47-63 Hz supply
  • High contrast 9mm LED display
  • Low cost - High performance
  • Panel or din rail mount enclosure
  • 4-20mA retransmission
  • Applications include the control of actutators in critical loops

The VP100 is an electronic motor positioner which operates within the motor feedback circuit. It accepts an input of 4-20mA and a motor position feedback signal from a three wire potentiometer, generates 2 independent relay contact outputs and displays the motor or valve position in % (percent) open.

The VP100 incorporates auto/manual transfer by front push button. In manual mode, the user is able to drive the servo motor to any desired position with the ramp up or ramp down push button, ensuring the user always has control of the motorised valve or gate position in the event of loop failure.

TECHNICAL SPECIFICATIONS

Input
The instrument accepts an input signal of 0-20mA or 4-20mA with 100 Ohms input impedance and a feedback signal of 100 to 10,000 Ohms from a three (3) wire potentiometer or 4-20mA current loop.

Output Relays
The instrument has two output relays for motor actuator control with a contact rating of 5 amps inductive at 240VAC with an RC filter for spark suppression.

Analogue Output
4-20mA output into 750 Ohms.

Display
A two (2) digit high contrast light emitting diode (LED) with a digit height of 10mm, a wide viewing angle and a viewing disance of 5 metres.
