Output Ratings
- Number of channels: The module has 8 channels, allowing control and monitoring of 8 separate outputs.
- Update time: The module has an update time of 5 milliseconds, indicating the speed at which it can process and respond to changes in input signals.
- Output Driver: The module uses Pulse Width Modulated (PWM) output drivers to control the output signals.
- PWM frequency: The PWM frequency of the module is 6.14 kHz, indicating the frequency at which the output signals are switched on and off.
- Filter: The module incorporates a 3-pole filter with a time constant of 500 milliseconds, which helps to smooth the output signals and reduce noise.
- Current output: The module provides a current output ranging from 4 mA to 20 mA, allowing for precise control and monitoring of current levels.
- Current output range: The current output range of the module is 0 mA to 25 mA, covering the entire range of possible current output values.
- Isolation: The module has 0 Vrms isolation, providing electrical isolation between the output channels and other components of the system for safety and noise reduction.
- Max load resistance: The module can drive a maximum load resistance of 600 ohms, which includes both the load resistance and any resistance in the wiring.
- Current readback: The module provides 8-bit current readback, allowing for monitoring and feedback of the actual output current levels.
- Readback isolation: The module has a common mode rejection ratio (CMRR) of 60 dB and a common mode rejection voltage of 200 Vdc for readback isolation, reducing interference and ensuring accurate current readback.
- Resolution: The module has a resolution of 11 bits, providing a high level of precision in controlling and monitoring the output current.
- Accuracy: The module is software calibrated to achieve an accuracy of 0.2% of the full-scale range (0 mA to 25 mA) for precise control and measurement.
- Temperature drift: The module has a maximum temperature drift of 125 ppm/C, indicating the change in output accuracy with temperature variations.
- Readback accuracy: The readback accuracy of the module is 0.5% of the full-scale range (0 mA to 25 mA), ensuring accurate measurement of the output current.
- Readback temperature drift: The module has a maximum readback temperature drift of 400 ppm/C, indicating the change in readback accuracy with temperature variations.
