2.5 Internal Series Resistor Switch
The GT200-HT-EI has an internal series resistor (270 Ohm /2 W) required for the HART channel, this allows up
to 13 HART instruments to be connected. When the power of the series resistor is more than 2W, you must use an
external series resistor (250 Ohm /3 W), allowing the gateway to be connected to up to 15 HART instruments.
Switch to ON, using the internal series resistor
Switch to OFF, using the external series resistor
