NI PXIE-8840QC current module

Electrical isolation and notes on earthing The following illustrations show the parts of the devices’ circuit which are electrically isolated from each other as well as the internal connections which exist. Both the creepage distances and clearances as well as the test voltages used correspond to DIN/VDE 0160. The 6.3 mm Faston terminal in the lower left corner has to be connected directly and on the shortest possible way to the switch cabinet earthing using a wire with a cross section of 6 mm2 in order to ensure safe earthing and as an EMC measure

The connection to the ABB Procontic CS31 system bus is made by means of a 3-pole detachable terminal block. Please observe:
All of the CS31 devices, no matter whether they are master or slave devices, are connected with the twisted-pair bus line as follows: – One core of the bus line is looped through via the BUS1 terminals of all devices to be connected to the CS31 system bus. – The other core of the bus line is looped through via the BUS2 terminals of all devices to be connected to the CS31 system bus.

24 V output voltage for the signal supply of the inputs

 The central unit 07 KR 91 provides a separate 24 V DC voltage output for the supply of the 20 binary input signals (for this purpose only). This 24 V output voltage is used only if an external 24 V DC power supply unit is not available. The internal 24 V power supply is overload-proof. The 24 V output voltage is ready for operation again approx. 2 minutes after an overload has been eliminated.

If the central unit 07 KR 91 is located at the beginning or at the end of the bus line, the bus terminating resistor (120 Ω) has to be connected additionally between the BUS1 and BUS2 terminals.
The shield of the twisted-pair bus line is looped through via the SHIELD terminals of all the devices to be connected to the CS31 system bus.
The handling of the CS31 system bus is described in detail in volume 2, System data.

Use as normal input signal

The signal is available in the user program in the operand E 62,00. The signal delay time is 7 ms. The updating of the operand E 62,00 is performed before the start of each program cycle. – Use as high-speed input signal: The signal is available in the user program in the operand E 63,14. The signal delay time is 0.02 ms. The updating of the operand E 63,14 is performed before the start of each program cycle. In the Dual Port RAM (DPR) this signal is updated after each CS31 bus telegram. With the aid of the function block WOL this signal can be read in the Dual Port RAM (word address C000:1FEH, Bit 14). – Use for the high-speed counter: The signal is used as counting input (10 kHz) for the high-speed counter. Terminal 3 – Use as normal input signal: The signal is available in the user program in the operand E 62,01. The signal delay time is 7 ms. The updating of the operand E 62,01 is performed before the start of each program cycle.
