Siemens SEZ91.6 : 0 to 20 V Phasecut Input to 0 to 10 Vdc. Analog Output
The SEZ91.6 interface facilitates seamless integration between phase cut controllers and controlled devices, specifically those operating on a standard 0 to 10 Vdc signal. This interface is particularly valuable in retrofit projects where existing systems need to be updated or expanded without replacing the entire control infrastructure.
At its core, the SEZ91.6 converts a proportional 0 to 20 Vdc phase cut signal from a controller into a 0 to 10 Vdc signal suitable for a variety of devices, including magnetic valves and damper actuators. This functionality is crucial for maintaining efficient and precise control over HVAC systems and other automated processes within a building.
One of the standout features of the SEZ91.6 is its adaptability. It offers two distinct operating ranges tailored for different applications: one for magnetic valves and another for damper actuators. This flexibility is achieved through two separate input terminals labeled "Y-Valve" and "Y-Damper actuator," which allow users to switch between modes without needing to modify the controller parameters. The design ensures that the device remains user-friendly and versatile, capable of meeting the diverse needs of modern building automation systems.
The interface requires an operating voltage of 24 Vac, which is standard in many building control systems. It is designed to be robust and reliable, with all terminal connections being short-circuit-proof and protected against polarity reversal. This level of protection enhances the longevity and reliability of the SEZ91.6, making it a dependable choice for long-term installations.
In terms of mechanical design, the SEZ91.6 features a compact plastic housing that encloses the printed circuit board and terminal connections. The housing is sealed with a plastic, shrink-wrapped sleeve, providing additional protection against environmental factors. The interface can be mounted in various locations, including control panels on DIN rails, within trunking, unit-mounted, in ceiling voids, or in remote distributor boxes, provided the environment is dry.
