Spirax Sarco Controller SP7-1/RPO Electrical Intelligent Positioner SP7-1 Positioner

Description

The Spirax Sarco SP7-1 Intelligent Positioner controls any valve actuated by a NAMUR-compliant straight or angle stroke pneumatic actuator. It guarantees an exact proportionality between the valve travel and the value of the electrical input signal (mA) transmitted to the positioner.
The positioner has a die-cast aluminum housing, is outdoor mountable, and can be mounted on pneumatic actuators with angular travel of -57° to 57° or straight travel of -28° to 28°. Available with or without a mounting kit and with or without a pressure gauge kit; specify type when ordering. Accepts mA signals as control signals with air supply pressures from 1.4 - 6 bar, also available for reaction control.
It has a local communication interface (LCI) and also offers "HART® communication (optionally HART®5 or HART®7). Options such as the SP7-11 with Profibus PA module or the SP7-22 with Foundation Fieldbus module are also available. In addition to analog position setpoint inputs, digital inputs are available for activating device control system functions, and digital outputs can output messages (alarms/faults).

air supply

A high quality gas source conforming to ISO 8573-1:2010 Class 3:3:3 must be used.

appliance

Can be used with any NAMUR-compliant actuator, including Spirax Sarco's BVA300 angular stroke actuator, the PN1600 series, the PNS3000 and PNS4000 series, the PN9000 series, the TN2000 series, and all pneumatic actuators.
