Analog Values – Safe and Standard
The brewery, which recently opened in April 2019, was designed and built by the brewery experts GEA Process Engineering A/S. All the brewery’s processes including ASi Masters and motors are controlled via PROFINET by two Siemens PLCs. All the tanks, kettles and plant components can be mutually connected by means of a system of 744 pneumatically activated process valves – controlled by eight ASi Masters from Bihl+Wiedemann. The ASi network also links together instruments and sensors that record the process data from each fermentation tank, such as the pressure, level and temperature.

Standard Analog Input and Output Modules up to IP67
Our analog input and output modules let you control many different connected sensors and actuators, so that a variety of applications are now available.
Our analog modules can read or write analog signals. They are available in protection ratings from IP20 to IP67 for any ambient conditions.
Safely Monitor Analog Signals
With our ASi Safety modules for analog inputs you can safely monitor and evaluate analog process variables such as temperature, pressure or speed. In addition to various encoders, thermocouples and temperature sensors, voltage and current values can also be monitored.
The modules safely report (up to SIL 3) whether the input signal (such as temperature or distance) is within freely configurable ranges .
Examples for Safety Functions
Application Example: Safe Distance and Position Monitoring
Easily read signals from analog distance sensors with our analog input modules, or encoder signals using our speed monitor. Now you can simply and safely monitor and process positions, distances or speeds. The safe ranges can be easily defined using our ASIMON360 configuration software.
The illustration below show an example of safe distance and position monitoring on a driverless transport system. Safe Link can be used, for example, to safely send the result of the distance and position monitoring over WLAN to a fixed base station. In addition, the base station can send safe signals to the driverless transport system to turn it off in emergency situations.
Application Example: Safe Speed Monitoring
The Bihl+Wiedemann speed monitors provide an efficient means of safely processing encoder signals. For example you can monitor a safely reduced speed for setup mode.
Other Safety Functions for EN 61800-5-2 Drives
Following are additional safety functions you can easily carry out using analog modules from Bihl+Wiedemann:
Simple Configuration in ASIMON360
Using ASIMON360, the configuration software from Bihl+Wiedemann, safe analog modules can be very simply configured with graphical assistance.
Learn how to seamlessly integrate safe sensors and actuators as well as safety monitors into all common automation systems with ASi Safety. Safe and unsafe signals can be transmitted on the same line.
PLC Independent Safety Technology
Discover the advantages of our safety and wiring technology, which is system and manufacturer-neutral. In this way, it enables simple, fast and thus cost-effective commissioning.
Discover how easy muting is with Bihl+Wiedemann's muting modules. All signals required for muting can be connected to a single module.
Selection of Mode of Safe Operation
Read all about how our TÜV-certified device facilitates "selection of mode of sfae operation selection": A standard HMI allows you to safely select up to 5 different operating modes for a maximum of 6 plant sections – each with unique safety functions.
