Analog Inputs
A/D Wiring Connections
The SeaConnect 370 has two 12-bit differential A/D inputs with polarity. The software-selectable
measurement ranges are 0-10V and 0-24 mA. For proper operation when current loop mode is selected,
a precision 200Ω resistor is placed in the circuit between positive and negative inputs via a software
controlled switch.
