FlyVi technologies has vast experience in design and development of Data Acquisition and process control systems. FlyVi technologies has successfully interfaced various sensors Viz. RTD, Thermo couple, pressure sensors, various MEMS sensors along with Discrete Inputs and outputs with the in house developed controller boards. The required MMI interface with capacitive touch panel with elegant look is also in-house.
The digital servo module (DSDM) is built around a 32 bit controller with associated circuits. The system has 3 Nos. of isolated analog input facility which can be selected as either 4-20ma inputs or 0-10V inputs using jumper selection. Similarly there is a facility for 4-20ma / 0-10V analog input which is taken as reference signal for PID loop. The PID output is given in both 4-20ma and 0-10V format with isolation. There is a RED LED in the PCB glows to indicate when there is a OPEN in 4-20ma output. The main features of this system are: 24V +/-4V, DC power input. Three Channel Current, Position Inputs. 4-20 ma Current / 0-10V with Isolation. (Conversion accuracy 0.05%) Single Channel Current, Position Inputs. 4-20 ma Current / 0-10V without Isolation (Conversion accuracy 0.05%)
Module Output: PID Controller Output1, 4-20 ma +/-50uA with Isolation PID Controller Output2, 0-10 V +/-20 mv. Fault Annunciation through potential free relay contacts.

cPCI based switching boardThe card is a cPCI, 3U form factor system with necessary connectors at the front panel. As the name indicates, the primary function of the card is to switch two sets of 3 modem inputs to a single output for radio connectivity. The rear end of the card is mounted with P1 and P2 connectors for cPCI connectivity. These connectors have all the cPCI bus signals along with power supply lines. The electronics on the MSB board requires +3.3V, +5V and +12V DC power which has been derived from the cPCI bus. cPCI interface signals from P1 and P2 connectors are first routed to the PCI to serials bridge controller. The PLX technology make OXuPCI952_LQFP176 has been used as PCI to serial bridge controller, incorporating PLX ultra high performance Oxford 950 UART technology. Modem Switching Board (MSB) is a 3U cPCI form factor Extended temperature Operation (-40°C to +85°C). Multiplexer Card used to switch any one of the two 2.4 kbps, 9.6 kbps, Hurricane Modems cPCI bridge interfaced to a 32 bit controller. 20 Mechanical relays used for modem signal switching Isolation transformer with impedance matching circuit for Modem audio signals < 5W power requirement |
