POSITIONERS & CONVERTORS

PI991 INTELLIGENT POSITIONER

The microprocessor-controlled positioner PI991 is designed to control pneumatic valve actuators and can be operated locally or by means of control systems. The advanced diagnostic can be partially shown on the local LCD of the positioner or fully on a PC or a DCS workstation with a DTM based software (VALcare or Valve Monitor). The positioner is available with different communication protocols. This includes versions with analog setpoint (4 to 20 mA) and superimposed HARTor FoxCom signal; digital with FoxCom protocol, or fieldbus communication according to PROFIBUS-PA and FOUNDATION fieldbus H1 according to IEC 1158-2 based on FISCO. The PI991 also has the capability to control a Partial Stroke Test (PST) that offers operators a tool to identify the trouble-proof function of ESD (Emergency Shut Down) valves.

PP981 PNEUMATIC POSITIONER

The ADCATROL PP 981 positioner requires an input signal of 0,2÷1bar (3÷15psi) for the proportional control actuator. The positioner compares the output signal from a controller with the position feedback and varies a pneumatic output signal to the actuator accordingly. The actuator position is therefore guaranteed for any controller output signal and the effects of varying differential pressure.

PE986 ELECTRO-PNEUMATIC POSITIONER

The ADCATrol PE986 positioner requires an input signal of 4÷20 mA for the proportional control actuator. The positioner compares the output signal from a controller with the position feedback and varies a pneumatic output signal to the actuator accordingly. The actuator position is therefore guaranteed for any controller output signal and the effects of varying differential pressure.

TZIDC ELECTRO-PNEUMATIC POSITIONER

The ADCATrol TZIDC is an electronically configurable positioner with communication capabilities designed for mounting to pneumatic linear or rotary actuators. It features a small and compact design, a modular construction, and an excellent cost-performance ratio. Fully automatic determination of the control parameters and adaptation to the final control element yield considerable time savings and optimal control behaviour.

PC25 FIELD I TO P CONVERTOR

An instrument that converts a standard DC signal to a standard pneumatic signal, for the change-over from electrical controllers to pneumatic control valves, or from electrical measuring system to pneumatic controllers. The PC25 is a force balance device, which converts a 4...20 mA input signal into a proportional 3...15 psi (0,2...1 bar) or 6...18 psi (0,4...1,2 bar) output signal, with a respective supply pressure of 1,7 – 5 bar.
