TM32 analog input module
Category: ARIS MT substation automation systems
TM32 analog input module is intended for remote input of analog current measuring signals ranging -22 to +22 mA.
Performance data
- 32 current channels
- Input resistance – 110 Ohm (0.1 %)
- Over-voltage protection – 16 V
- Measured current range: –22…+ 22 mA
- ADC capacity – 14 bit
- Accuracy of measurements – 0.1 %
- Conversion time for all channels – 1 ms
- Galvanic isolation – 1500 V (power supply/interface lines, measurement circuits)
Main functions
- Data input via 32 current measurement channels, measurement range is –22…+ 22 mA (calibration available via software)
- Averaging time definition for each channel (at least 20 ms)
- Definition of sporadic thresholds for each channel
- Definition of substitution values for each channel
- Calculation of output value in accordance with with user settings
- All events (detection of module failure, modification of module`s configuration, module activation/deactivation, sporadic thresholds exceeded) are stored in the non-volatile memory
Additional capabilities
- Archive with capacity for 660 events (detection of module failure, modification of module`s configuration, module activation/deactivation, sporadic thresholds exceeded)
- Light indicators reporting channel status, port states, power supply/module status
- Module`s time can be synchronized either through the central controller, or via an external GPS receiver with an accuracy of 1 ms
- Regular self-testing of the module (monitoring of ADC operation, measurement circuits' operating voltage)
- Built-in real time clock
