For information on the failure simulation function, please It mimics sensors or switches such as door contact switches, refer to Failure Simulation on p. 8. Hall sensors, and sensors for wheel speed and oil tempera- ture. Each of the DS2621's 10 channels can be software- confi gured as a voltage source, a current sink, a digital output simulation or a resistance simulation. I/O Functionality The DS2621 has 10 fl exibly confi gurable output channels IOCNET connection I/O connector to make analog and digital signal generators available. To increase the current or voltage range, up to 10 channels can DC Current sink be bundled in parallel or in series. For example, two voltage DC Voltage sources can be switched in sequence, or two current sinks in source Fuse parallel, to increase the output voltage or current. The digital Digital output FRU Controller output can be used as a switch and can generate time- and Fuse Resistance frequency-dependent signals (such as PWM). For example, simulation Signal generator circuits the resistance simulation can be used to pass the specifi ed . 10 .. 1 temperature changes to an ECU via the environment model. Status LED Channel bundling is supported by the software. Confi gu- rationDesk displays the bundled channels as one single I/O function. 16 2013 I/O Hardware / SCALEXIO Technical Details Parameter Specification General n 10 galvanically isolated channels n Up to 10 channels can be connected in sequence or in parallel to increase the current range to max. ±320 mA and the voltage range to max. ±60 V n Status LED for overall board status Signal generation Voltage source n Output voltage ±20 V (Flexible Out 1) n Output current ±40 mA n DAC resolution 16 bit n Signal frequency 0 … 140 kHz (sine) Current sink n Voltage range ±60 V n Current range ±40 mA n DAC resolution 15 bit n Signal frequency 0 … 140 kHz (sine) Resistance simulation n Resistance range 17.5 Ω ... 1 kΩ n Voltage range ±20 V n Current range ±40 mA Digital output n Voltage range ±60 V n Current range ±40 mA n Signal frequency 0 … 1 MHz Failure simulation (p. 8) n Onboard failure routing unit (FRU) n Signal forwarding to central FIU n Relay-based n Available for each channel Electronic fuses n 100 mA RMS ECU (effective value) n On ECU side tripping at I = 100 mA n On sensor side with configurable trip range I = 5 ... 40 mA Internal communication interface n IOCNET Physical data Physical size n 410 x 100 x 15 mm (16.1 x 3.9 x 0.6 in) n Requires 1 slot Voltage supply n 24 V Order Information Product Order Number DS2621 Signal Generation Board n DS2621 17 2013
