Electro-Pneumatic Digital Positioner

The SP500 HART® electro-pneumatic digital positioner supporting HART® communication protocol comprises of a digital data transfer and communication over existing 4-20mA wiring, requiring no additional power supply or wiring to the positioner.

The SP500 HART® electro-pneumatic digital positioner supporting HART® communication protocol comprises of a digital data transfer and communication over existing 4-20mA wiring, requiring no additional power supply or wiring to the positioner. Through the protocol, the positioner can be configured and process parameters updated or modified remotely using a PC or handheld device. The positioner permits continuous condition monitoring, leveraging higher processing power to integrate the SP500 HART and information about its adjacent control valve into data logging applications and advanced control strategies. The unit is also available with 4-20mA retransmission, software switches and the ability to be powered by an external 24V DC power supply. The product minimizes downtime and enables the full body of features to be utlized with ease. The non-contact valve position feedback system simplifies installation while improving reliability over traditional mechanical methods.
