Analog Values – Safe and Standard
Bryggeriet, som just invigts i april månad 2019, är projekterat och byggt av bryggeriexperterna GEA Process Engineering A/S. Bryggeriets alla processer inkl. ASi-masters och motorer styrs överordnat av två PLC:er från Siemens via Profinet. Alla tankar, pannor och anläggningskomponenter kan kopplas samman inbördes med hjälp av ett system med 744 pneumatiskt aktiverade processventiler – som styrs av åtta ASi-masters från Bihl+Wiedemann. Till ASi-nätverket är dessutom kopplat instrument och sensorer som registrerar processdata från varje jäsningstank, som exempelvis tryck, nivå och temperatur.

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
Safety thermocouple module in detail:
- Monitors type J, K, N, R, S thermocouples
- Meets EN 746-2, Par. 5.7.2.b for use in thermal process equipment
- Safety temperature limiter and monitor with overtemperature shutoff of an industrial oven per SIL 3 / PLe (Machine Directive DIN EN ISO 13849-1 PLe)
- Highly accurate transmission of calibratable process values over gateways to the higher level control system
- Chip card for simple device replacement
- Safely (up to SIL3) send switching thresholds to the controller, e.g. through the PROFIsafe gateway
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 drives acc. to EN 61800-5-2
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.
Functional safety
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.
Muting
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.
