Analogue Input, 4-fold, MDRC
Description
The device is a modular installation device with a module width of 4 space units in Pro M design for installation in distribution boards. The connection to the ABB i-bus is established using a bus connection terminal on the front side. The assignment of the physical address, as well as the setting of parameters, is carried out with Engineering Tool Software ETS.
The device enables you to record and process four analogue input signals in accordance with DIN IEC 60381, e.g. 0...1 V, 0...5 V, 0...10 V, 1...10 V, 0...20 mA, 4...20 mA. Furthermore, PT 100 and PT 1000 sensors in 2- and 3-conductor technology, 0...1,000 ohm resistors and a selection of KTY sensors can be connected. It is also possible to adapt the device to user-defined KTY sensors by entering a characteristic curve. Floating contacts can also be connected to the device.
The processing of the input signals is carried out in the application Threshold measurement 4f.
The object values can be set for each input separately in the application. The output value can be sent as a 1-bit value, or a 1-, 2- or 4-byte value via the bus.
Due to the flexibility allowing the measurement curve to be adapted, it is possible to mask out certain areas of the measurement curve or to even offset or correct them. Measured values can be averaged over 1, 4, 16 or 64 measurements using the Filter function. The output value is smoothed via the mean value. As one measurement is taken every second, the setting for 64 measurements per output means that the output value is sent after about 64 seconds.
It is possible to set two thresholds per input. The thresholds each have an upper and lower limit which can be set independently. The thresholds themselves can be changed via the bus.
There are four further calculation objects available. It is thus possible to compare two output values or calculate the arithmetic mean. The options less than, greater than, addition, subtraction and averaging are available.
