I/O Hardware / SCALEXIO DS2680 I/O Unit MultiCompact unit for powertrain and vehicle dynamics scenarios Highlights n 140 channels for extensive I/O functions n Galvanically isolated as a unit n Compact half 19" unit n Attractive price The DS2680 I/O Unit is a MultiCompact unit for the function, i.e., they are dedicated analog or digital channels. SCALEXIO system that provides all the I/O channels required With its predefi ned channels, the DS2680 has an attractive for the hardware-in-the-loop simulation of transmission or price, and is ideal for specifi c application scenarios. vehicle dynamics ECUs. Most of the I/O channels have a fi xed I/O Functionality Testing Electrical Failures The DS2680 has numerous I/O channels, each with a mostly The DS2680 includes a Failure Insertion Unit (FIU) for testing predefi ned function. You can choose between analog and ECU behavior in the event of a failure. It can be used as a digital inputs and outputs, resistance simulation channels, central FIU for the SCALEXIO system. Each channel has a and special I/O channels (for details, see p. 4). Signal mea- failure routing unit (FRU) for switching the connection to surement and generation can be time-triggered or angle- the FIU via the fail rails.

Real Loads Component Variants Substitute loads can be plugged onto the DS2680 internally The DS2680 is available with and without an integrated if required. An exchangeable load board is available for bus board. The integrated bus board provides two channels you to mount different plug-on loads. Real loads or large for each of the bus protocols LIN, CAN and FlexRay. If you substitute loads can be connected externally via the load need more or different bus channels, for example, four CAN connector provided for them. channels, you can use a HighFlex bus board in addition or as an alternative. 22 2013 I/O Hardware / SCALEXIO Technical Details Parameters Specification General n Galvanically isolated as a unit Signal measurement n Max. 6 A per channel n Substitute loads pluggable, up to 2 W per measurement channel n Connector for real loads n Channel bundling to increase current carrying capacity n Multifuse for electrical safety n 20 analog inputs n Only voltage measurement (Analog In 1) n Measurement range 0 ... 60 V n Resolution 16 bit n 30 digital inputs n Voltage measurement (Digital In 1) n Trigger value 0 ... 24 V n Voltage range 0 ... 60 V n 18 variable inputs n Voltage measurement digital (Flexible In 2) n Voltage range 0 ... 60 V n Trigger value 0 ... 24 V n Current measurement analog and digital n Measurement range ±18 A n Resolution 16 bit (analog) Signal generation n 15 analog outputs (DC) n Only voltage generation (Analog Out 1) n Output voltage 0...10 V n Output current -5 ... +5 mA n Resolution 14 bit n 8 analog outputs (DC) n Output voltage 0...10 V (Analog Out 4) n Output current -5 ... +5 mA n Resolution 14 bit n Current sink: Current range -30 .. +30 mA n 7 analog outputs (DC) n Only voltage generation (Analog Out 3) n Output voltage -20...+20 V n Resolution 14 bit n Effective inner resistance 250 Ω n 12 resistance simulation channels n Resistance range 16 Ω ... 1 MΩ (Resistance Out 1) n Voltage range -3 ... +18 V to GND n Current range -80 .. +80 mA n Power max. 250 mW n 28 digital outputs n Configurable as low-side/high-side switch or push/pull (Digital Out 1) n Low-side = GND n High-Side V or Dig-Out-Ref Bat n High-side voltage range: 5 ... 60 V n Current range -80 .. +80 mA Special I/O channels n 2 analog input and output groups, n 1 ADC e.g., for lambda n 1 DAC (Analog In 2, Analog Out 2, Load 1) n 1 load (component channel) n Voltage range -10 ... +10 V n Current range -5 .. +5 mA Voltage supply n 1 channel to control the power unit n Control of Lambda Genesys current supply (Power Control 1) n 6 power switches without current n Voltage 60 V measurement (Power Switch 2) n Continuous current 4 x 6 A per channel (total current max. 50 A) 23 2013 I/O Hardware / SCALEXIO Parameters Specification 1) Buses n 2 CAN (CAN 1) n Configurable as high-speed or low-speed CAN n Conventional CAN V Bat n 2 LIN (LIN 1) n Configurable as K-line n Conventional LIN V Bat n 2x FlexRay (FlexRay 1) n Only 4 bus lines, i.e., 1 fault-tolerant FlexRay bus (channels A + B) or 2 FlexRay buses (channel A) n Conventional FlexRay V Bat Failure Insertion Unit General n Voltage ±60 V n Failure switch for up to 48 A n Continuous current for high-current fail rail 48 A n Continuous current fail rail with low capacitance 1 A Failure types n Broken wire n Short circuit to GND or U Bat n Crossed wire between two channels n All failures with optional bouncing Internal communication interface n IOCNET Physical data Physical size n 475 x 132 x 215 mm (18.7 x 5.2 x 8.5 in) Voltage supply n 24 V 1) Only for DS2680 with bus support Order Information Product Order Number DS2680 I/O Unit (without bus support) n DS2680_ONLY DS2680 I/O Unit (with bus support) n DS2680_2672 DS2680-IL Load Board (exchangeable load board) n DS2680_IL 24 2013
