I/O system

Clamp modules

Clamp modules are passive modules for 2- or 3-wire installations, whose contacts are vertical electrical connected internal. Within the module the backplane bus feed-through. The module does not have any module identification, but is considered at the maximum number of the modules.Through the application of the clamp modules, distributors for power supply could be realized easily and enables so the connection of active supplied sensors like proximity switch. The wiring is done via timesaving and secure cage clamp technique.

Characteristics:

  • Maintenance-free cage clamp technique;
  • Backplane bus feed-through;
  • Max. terminal voltage 10A;
  • Potential separation 500 Veff (field voltage to bus);
  • Mounting on a 35mm DIN rail.

 

Power modules

In the system SLIO the power supply is provided via power modules.

Both the bus interface as well as the electronics of the connected peripheral modules are supplied with power via the power module (PM) integrated in interface module (IM). The DC 24 V load power supply for the connected peripheral modules is provided via a further connection in the PM. With the help of color-contrasted power modules within the system further potential areas for the DC 24 V load power supply can be defined. The two-component design allows for the easiest of service by separating the electronics from the terminal module.

Characteristics:

  • Power supply of the sensor/actuator-level;
  • Nominal input voltage DC 24 V;
  • Output current max. 10 A;
  • Isolation from potential groups;
  • Front integrated status LEDs;
  • Mounting security by reverse polarity and overvoltage protection.

 

Signal modules digital

Signal modules (SM) to connect sensors and actuators are the interfaces of the system to the process. Digital signal modules acquire the binary control signals to and from the process level. A variety of different digital signal modules provides exactly the I/O modules, which are required for each task. The digital modules differ in the number of channels, voltage and current ranges, isolation, and diagnostic and alarm capability.

Characteristics:

  • Electrically isolated digital inputs and outputs to the backplane bus;
  • 2, 4 or 8 channel;
  • Various modules, suitable for switches and proximity switches as well as for measuring transducers;
  • Direct mapping and readability of the channel conditions via status LEDs;
  • Safe and time-saving installation by the terminal assignment mounted on the module;
  • When changing the module equipment identification (BMK) is retained on the TM;
  • Individual single-channel lettering on insertion strip;

 

Signal modules analog

Signal modules (SM) to connect sensors and actuators are the interfaces of the system to the process. Analog signal modules acquire the analog control signals (e.g. measurement data) to and out of the process level. Depending on the application and type the control signals are acquired from the process level and converted into interpretable signals for controlling. Analog output modules convert the internal control signals into signals suitable for the process level. A variety of different analog signal modules accurately provide the inputs and outputs that are required for each task. The analog modules differ in the number of channels, voltage and current ranges, isolation, and diagnostic and alarm capability.

  • 2 or 4 channel;
  • 12 bit or 16 bit resolution;
  • Functions of the inputs / outputs programmable;
  • Most various assemblies, suitable for measuring transducers (current/voltage, resistance or temperature sensors);
  • Direct mapping and readability of the channel conditions via status LEDs;
  • Safe and time-saving installation by the terminal assignment mounted on the module;
  • When changing the module equipment identification (BMK) is retained on the TM;
  • Individual single-channel lettering on insertion strip.

 

Communication processors

Communications processors are used to connect different target and source systems, e.g. via Ethernet to higher-level ERP systems or serially to scanners, printers and other peripherals.

CP 040

The communication processors CP 040 enable the serial process coupling to different target and source systems. Depending on the module they have a RS232 or a RS422/485 interface.

  • Support for all standard protocols ASCII, STX/ETX, 3964(R) and Modbus (master, slave);
  • Internal communication via VIPA FBs;
  • Compact design;
  • LED status indicator;
  • Electrically isolated to the backplane bus;
  • Assembly with 35 mm profile rail.

 

Function modules

Function modules (FM) are intelligent modules that perform technological tasks such as position determination, counting and positioning, and other complex functions in the automation independently. They are used when there are high demands on accuracy and dynamic in the starting of automation tasks. Different functional modules, for example counter modules, SSI modules provide exactly the functions that are required for the respective tasks.

  • Supports fast counter systems up to 1 MHz;
  • Counting direction invertible;
  • Integrated digital outputs;
  • For direct connection of incremental encoders;
  • Electrically isolated to the backplane bus;
  • Direct mapping and readability of the channel conditions via status LEDs;
  • Safe and time-saving installation by the terminal assignment mounted on the module;
  • When changing the module equipment identification (BMK) is retained on the TM;
  • Individual single-channel lettering on insertion strip.

 

Interface modules

Interface modules (IM) form the interface between process level and parent bus system. All control signals are transmitted through the internal backplane bus to the electronics module (EM). In the case of the interface module the bus interface and power module (PM) are integrated in a single casing. Both the bus interface and the electronics of the connected peripheral modules are supplied with power via the integrated power module.
