G-7903B&C Analog Multiplexers

The G-7903 Analog Mutiplexers are capable of mutiplexing up to 8 analogs. The G-7903B is used with systems that can tolerate a common ground for all 8 inputs. The G-7903C provides 8 differential inputs for use with systems where each analog input must be isolated for common. Functionally, the B and C versions are identical except for the input configuration.

Each analog input has it's own amplifier and can provide individual scaling to a common scale. The scale is inserted in the analog-to-digital converter on the G-7803C. Current loop shunt resistors are provided on each input for current voltage conversion.
Specifications

Data Rates: 30, 60, 120 and 240 bits per second and up to 19.2KB/S for fiber optic modules G-2001 and G-2003.
Inputs: 8 high impedance inputs provided with current shunt positions. Each input can be scaled to the G-7803c's input scale. Single-ended inputs on the G-7903B, differential inputs on the G-7903C.
Scan Coding: Switches provided to select the number of inputs scanned.
