The ABB digital positioner PositionMasterEDP300 boasts compact design, excellent performance, and high flexibility. The features of its locator are as follows: · High air capacity · Diagnostic capabilities · Overpressure resistance · Durability · Excellent environmental adaptability · Easy to operate · Explosion-proof certifications—ATEX—IECEx—FM/CSA—GOST · Suitable for SIL2 safety circuits · Extended diagnostics Applications The ABB locator comes with a built-in LCD indicator featuring multi-line display, as well as 4 operation buttons for debugging, configuration, and monitoring of real-time operations. Additionally, appropriate DTM/EDD can also be used through the provided communication interface. Communication This locator supports HART5 and HART7 communication. Input/Output In addition to analog position setpoint input, this locator is also equipped with digital input functions that can be used to activate various control system functions within the device. The digital output function can be used to output the collected alarm or fault information. Module design At any time, the basic model can be enhanced by installing optional equipment. Optional modules for analog and digital feedback, an emergency shutdown module, and pressure sensors for valve diagnosis can be installed. The general-purpose analog input module can also be installed on any device that provides a 4…20mA signal connection. Furthermore, a mechanical position indicator, proximity switch, or 24V fine-tuning switch can also be provided to indicate the position independently of the master function. Diagnosis The ABB positioner comes with three optional pressure sensors, which are used for reliable diagnosis of the valve, the pneumatic actuator, and the positioner itself.
