Positioners

The analogue and digital versions of Schubert & Salzer compact positioners can be combined with all Schubert & Salzer pneumatic valve actuators. The integration of the „top-mounted“ positioner into the valve actuator means that no moving parts, such as the stroke return, are freely accessible. This increases operational reliability and resets the valve position without backlash.

2-/4-wire versions:
Schubert & Salzer positioners are available as 2- or 4-wire versions for linear and rotary actuators. They have standardised, analogue signal voltage and current input (0/4-20 mA; 0/2-10V) or IO-Link communication.

Ex and FM Versions:
For applications in potentially explosive atmospheres, Schubert & Salzer positioners are available with ATEX 2014/34/EU approval and FM certification (Factory Mutual Approvals) for Class I, Division 1 or Zone 0 intrinsic safety circuits or for Class I Division 2 non incendive circuits.

Smart positioner with IO-Link

With the optional IO-Link, valves with smart positioners can provide extensive status data, which, along with predictive maintenance planning, also significantly facilitates fault analysis and commissioning, for example.

Predictive Maintenance
Monitoring and evaluation of the status data available centrally via IO‑Link facilitate the predictive planning of maintenance measures.

Faster troubleshooting
Anomalies and deviations in control behaviour can be identified sooner and are easier to trace back to their cause. Physical access to the device is not necessary.

Simple commissioning and replacement
The standardised connection cable with an M12 plug comprises the positioning signal, position feedback, data transmission and even the power supply. The coded connectors not only significantly reduce the required cabling effort, but also technically rule out wiring errors in valves with IO-Link positioners. Replacement positioners of type 8049 automatically adopt the previously used parametrisation and are immediately ready for operation after a self-calibration.
