1. General Introduction
Siemens PS2 valve positioner is the most economical and widely used to control the final control element of pneumatic linear or part-turn actuators, come with aluminum, stainless or flameproof steel versions. It can be used with all pneumatic actuators and is available for delivery: In various enclosure designs and various materials (polycarbonate, aluminum, and stainless steel); For non-hazardous applications and also For hazardous applications in the versions including Intrinsic safety type of protection, Flameproof enclosure type of protection, Non-sparking type of protection and Type of protection dust explosion protection by enclosure. The communication type can be with 0/4 to 20mA control with/without communication through HART signal, PROFIBUS PA communication interface and FOUNDATION Fieldbus (FF) communication interface.
The positioner consists of: Enclosure and cover, PCB with corresponding electronics, Position detection system, Terminal housing with screw terminals and Valve manifold with piezoelectric valve precontrol. The valve manifold is located in the enclosure, the pneumatic connections for the inlet air and the positioning pressure on the right-hand side of the enclosure. A pressure gauge block and/or a safety solenoid valve can be connected there as options. It can be fitted to the linear or part-turn actuator using an appropriate mounting kit. The circuit board container in the casing provides slots for separately ordered boards with the functions of Position feedback module as a two-wire signal 4 to 20mA; Alarm module (3 outputs, 1 input); Limit signaling through slot-type initiators or mechanical contacts (mechanical limit switch module).
