ABB 07KR31 FPR3600227R120 Displacement speed clamp

The PGA applies a gain of x1 or x10 to the differential channel from the PGA multiplexer, and produces a single-ended output. PGA gain is selected by the GAIN_X1_L control line. Analog-to-Digital Conversion The output of the PGA is buffered by a unity gain buffer and digitized by the 16-bit successive approximation A/D Converter shown in Figure 1-3 on page 26. The ADC has built-in sample and hold. Each conversion is initiated by the sample command, and the read ADC strobe writes the digitized value to the data buffer through the internal data bus. Total conversion time is 10 µsec at the highest sample rate available for the high-performance option and 20 µsec for the standard performance option. The sample command takes 2 µsec, leaving 8 µsec for high-performance and 18 µsec for standard performance for the actual A/D conversion. The ADC timing is shown in Figure 1-3 on page 26.

Unpacking Procedures 

CAUTION: Some of the components assembled on VMIC’s products may be sensitive to electrostatic discharge and damage may occur on boards that are subjected to a high-energy electrostatic field. When the board is placed on a bench for configuring, etc., it is suggested that conductive material should be inserted under the board to provide a conductive shunt. Unused boards should be stored in the same protective boxes in which they were shipped. Upon receipt, any precautions found in the shipping container should be observed. All items should be carefully unpacked and thoroughly inspected for damage that might have occurred during shipment. The board(s) should be checked for broken components, damaged circuit board(s), heat damage, and other visible contamination. All claims arising from shipping damage should be filed with the carrier and a complete report sent to VMIC together with a request for advice about the disposition of the damaged item(s).

Physical Installation 

 Do not install or remove the board while power is applied. De-energize the equipment and insert the board into an appropriate slot of the chassis. While ensuring that the board is properly aligned and oriented in the supporting card guides, slide the board smoothly forward against the mating connector until firmly seated.
