2.3.1 Output Terminals
The output terminals 9 and 10 are connected to a power supply
having a nominal 24 Volt DC voltage and capable of supplying 100mA
for the SC170. In the analog mode, these signal conditioners require a
maximum of 23mA. The + OUT and - OUT terminals of the power
supply. The maximum series resistance in the circuit (including wiring
lead resistance) can be calculated using the formula:
Vs - 12
Rs = ————————
0.023
The following chart gives maximum series resistance:
2.3.2 Case Ground
Terminal 8 provides a connection to the metal enclosure of the signal
conditioner. For safety, optimum performance and EMI immunity the
case of the instrument should be connected to a good local earth
ground. When using grounded sensors that are connected to the
local electrical ground, then the signal conditioner case should be
connected to that same ground point.
