HE 5120 CAN Display Features 5-digit 7-segment display, display range -9999 to 99999, decimal point free selectable 3x LEDs for status / measuring range display CAN connection: CAN-specification according to 2.0A / 2.0B / ISO11898 (max. 1 MBaud), CANopen protocol according to DS301 and parts of DS 401 DIP-switch (8-pin) for CAN node address and switchable CAN bus termination Coded rotary switch 0-9 for CAN baud rate: 10 kBaud to 1 MBaud, Option: automatic baud rate recognition Switching output: 1 relay, potential free change-over contact (250 V AC / 5 A) Brief Description The CAN display HE 5120 is applied for the visualization of process data like temperature, pressure, weight, level, etc. The different physical units are identified by three LEDs. The instrument has a switch contact which can either be used as a digital output or limit comparator. The CAN bus connection is according to ISO11898. The Siemens microprocessor C505C with integrated FULL CAN controller supports the transmission according to the CAN specification 2.0A / 2.0B with max. 1 MBaud. The instrument can be programmed per parameter setting via CAN bus which information is to be displayed and in which format . The display is thus able to filter the relevant data from the complete CAN messages by itself without being addressed directly. The parameter settings are stored in an EEPROM. This means that, after a shut down, the instrument can start the operation again without repeating the process of parametrization. Downloads: HE 5120 Data Sheet   HE 5120 Manual

HE 5900 Basic Trays for Mod I/O Mounting on DIN-Rail The basic trays are intended for DIN-rail mounting according to EN 50022. The mounting is carried out by locking the metal ledge (A) on the back side below. For dismantling a basic tray the metal ledge (A) must be released. Installation / Removal of the Modules Module installation into a basic tray: Slide in the module at the respective place. Listen to the 'click' for proper engaging. The installation of the modules HE 5910 or HE 5911 (fieldbus coupler) always must be placed at the absolutely left position. All other modules can be installed at any position. For removing: Release the two ledges (B) and pull out the module. To keep the specified protection degree (IP20) emty slots must be protected by slot covers. Screw-/ Plug-in-Terminals The screw-/plug-in-terminals can be plugged in from above or below into the module housing (audible locking). Removing the screw-/plug-in-terminals takes place by levering out at position (C), e.g. with a screwdriver. Due to protection against contact, not connected terminal blocks should remain in their places.

HE 5894 HMI and Programable Logic Control Unit
HE 5950 Operation Terminal

HE 5894 HMI and Programable Logic Control Unit Features Compact and rugged hardware Operation with touch screen Brilliant colour display,  7" or 10" with 262144 colours Operating system  \'embedded\' LINUX Real time soft PLC with  CoDeSys V.3.3 Convenient debug and commissioning tools Integrated grafical visualisation system Function keys for general system functions Data exchange  between visualisation and PLC Control of an extenal IMOD System Four independent serial interfaces RS-232, 2x RS-485 and CAN LEDs for system status Fanless design due to \'low power\' components Solid state memory Brief Description The touch panel programmable logic controller (PLC) HESCH HE 5894 is a device of the human-machine interface class with integrated PLC functions. The HE 5894  is intended for creation of automated process control systems in various industries, power generation, the building automation sector and transportation. The integration of the control program and the user interface in one common device and one programming environment  results in significant time and cost advantages. By standardising the description of the data in the control program and in the visualization, errors are avoided.  Adjustable task priorities enable fast cycle times of the soft-PLC as well as short response times of the user interface. An integration of the control terminals into existing networks is possible via the Ethernet interface.  The computer is fanless, thanks to the use of \'low power\' components and solid state memory for program and data. The operation is done directly on the screen surface, general system functions and special functions of the program can be started with the additional control buttons with LED indication.
