Analog Values – Safe and Standard

Bryggeriet, der netop er blevet indviet i april måned 2019, er projekteret og bygget af bryggerieksperterne GEA Process Engineering A/S. Overordnet styres alle bryggeriets processer inkl. ASi-Mastere og motorer af to PLC’er fra Siemens via Profinet. Alle tanke, kedler og anlægskomponenter kan indbyrdes forbindes ved hjælp af et system af 744 pneumatisk aktiverede procesventiler - der styres af otte ASi-Mastere fra Bihl+Wiedemann. På ASi-netværket er endvidere koblet instrumenter og sensorer, der registrerer procesdata fra hver gæringstank, som eksempelvis tryk, niveau og 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.

Analog control, e.g. with:

  • 0 … 20 mA
  • 0 …10 V

 

Connection options for various sensors:

  • 4 ... 20 mA
  • 0 … 10 V
  • Pt100
  • Pt1000
  • Type J and Type K thermocouples
  • Balance cell controllers

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.

Safe speed monitors for encoders:

  • Monitor up to 2 axes, up to SIL3, PLe
  • For sine/cosine, SSI, TTL or HTL-Encoder
  • Detailed diagnostics and shut-off history via software
  • Chip card for easy device exchange
  • 22.5 mm width

Devices with local safe outputs:

  • 2 safe electronic outputs
  • Support of all safety functions acc. EN 61800-5-2
  • Any number of safety functions can be implemented
    • Possibility to configure several functions or same function with different parameters for each axis
    • Max. 128 devices configurable

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.

Configuration made easy:

  • Drop-down for safe range selection
  • Several ranges can be defined for each module
  • Graphical assistance in configuration
  • Hardware catalog for simple module selection
