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.

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.
