Signal Converter (Current Output)

Bookmark and Share
  • SC-XX is a Electronic Card to Convert potentiometer / Resistance / Voltage input to Current Output.
  • In an extremely compact size of board 12 mm X 22mm X 73mm card mounted in a din rail enclosure of 23mm width X 83mm length X 35mm Height makes it a ideal product to use it with out enclosure in small size location as well.
  • SC-XX has a additional 5Vdc transmitter supply output makes it very suitable product for instrumentation industry. For heavy electrical noise atmosphere we have a model with isolated Input and output signal.
  • Customisation in Mechanical and electrical parameters is feasible for any Project requirement.
  • Span and Offset trim potentiometer to trim it and Power LED makes it look elegant and convenient for industry use.

DIN Rail Mounting




Mounting

For best performance of RHS-12 below points needs to be taken into consideration.
1) The hole in the panel should not be more than 9.5mm.
2) RHS-12 should be mounted with Star washer given along with the product and perpendicularity between the panel and axis of Sensor should be maintained.

Magnetic Cross Talk

If two RHS-12 units are to be installed closer than 2 inch (measured between the center of both shafts),a magnetic shield, such as a small steel plate should be installed in between to prevent one encoder from c a u s i n g s m a l l c h a n g e s i n r e p o r t e d p o s i t i o n t h r o u g h m a g n e t i c f i e l d c r o s s - t a l k .

The RHSS12-XSPI is a Absolute encoder which acts as a slave and communicate with master micro controller as per the standard Protocol of SPI.
As per standard protocol of SPI RHSS12-XSPI communicate with master protocol when the MOSI pin is active high or 3FFF hex data is sent on the bus and the CS pin need to toggle from low to high for only one clock pulse.
RHSS12-XSPI communicate in 16 Bit of Transmission. After each cycle of communication it is compulsory to toggle CS pin from high to low.
RHSS12-XSPI has a provision of Dual Output first SPI communication and PWM mode of communication 14 Bit and 12 Bit of Resolution respectively.
Number of sensors can be connected in daisy chain mode of 4 wire or (n+3 wire connection). please contact Mr. Pavan Kinariwala(pavankinariwala@gmail.com) for more information on the same.
RHSS12-XSPI will communicate the angle information in below pattern.
