GESADC Termination Board
Description:
The DTEC Ltd. GESADC termination board connects via
ribbon cable to the Gespac analog input card. This Gespac analog input card and
GESADC termination board allows connection and protection for 16 analog inputs.
The connection to peripheral equipment is provided by the screw type terminal
strips and the protection is provided by 15 VDC avalanche zener diodes. The
Gespac analog input is setup to accept an analog range of +15 to -15 VDC. The
GESADC termination board receives its' ground from the Gespac Card through the
ribbon cable, therefore failure to connect the GESADC termination board
properly to the Gespac card will result in no or improper operation of the
termination board.
Stock Item. US$145.00
Circuit Description:
The input channels of the Gespac analog input card can
receive a voltage range of -15 Vdc to +15 Vdc. The zener diodes protect the
input circuitry by shunting current when the input voltage is over 15.6 Vdc or
under -15.6 Vdc. The zeners are rated for 500 mWatt each. For download of
