SAUTER AKM115SAF332: Smart Actuator for ball valve, BACnet/IP

AKM115SAF332: Smart Actuator for ball valve, BACnet/IP

How energy efficiency is improved

Ball valve actuator with integrated, freely programmable controller and cloud connection in one

device. Can be integrated into a local building automation system via BACnet or into the

SAUTER Cloud via MQTT. Communicates via Ethernet, Wi-Fi and Bluetooth. Automatic adaptation to

the ball valve, precise activation and high energy efficiency with minimal operating noise and smart

functions

Features

• Smart Actuator as an intelligent IoT solution for autonomous control of heating and air-conditioning

applications in smart buildings

• Ready-made HVAC standard applications from SAUTER from the App Store allow efficient

installation and commissioning of small systems

• Applications are selected from the library via mobile app and installed on the Smart Actuator

• Ethernet switch, Wi-Fi interface and Bluetooth LE for flexible device communication and system

integration

• BACnet/IP communication (EN ISO 16484‑5) via Ethernet or Wi-Fi interface

• Convenient commissioning, parameterisation and remote access to the system via a mobile app or

with the SAUTER CASE engineering software

• As an IoT device, the cloud connection for remote access takes place via MQTT using TLS

encryption

• Enables creation of Smart Actuator networks with distributed intelligence

• Optionally, the Smart Actuator can be used flexibly in BA networks due to free programmability via

CASE Suite

• Real-time clock for calendar functions and time programmes

• Two universal I/Os for connecting external sensors and actuators

• Direct connection of up to two room operating units

• Flexibly expandable with up to four I/O modules for comprehensive control tasks

• Pre-assembled cables with mechanically and colour-coded connectors allow fast, error-free wiring

for Smart Actuator and SAIO 100 I/O modules

• Fitting without tools using a bayonet ring made of glass-fibre reinforced plastic

• BLDC motor technology enables extensive diagnostic functions

• Intelligent angle of rotation adaptation and detection including feedback signal

• Electronic, torque-dependent cut-off

• Disengageable gear unit for manual adjustment and local priority operation

• For operating the 2- and 3-way ball valves VKR, VKRA, BKR, BKRA, VKAI, VKAA, BKLI, BKTI and

BKTA, as well as 6-way ball valve B2KL
