3.4 Configuration Examples

3.4.1

Catalytic Sensor

This diagram shows how to connect GasTech catalytic sensors to the GTA-4100R. Compatible GasTech part
numbers include 61-0103, 61-0101 and 61-0203.
NOTE: If you are connecting a catalytic sensor to the GTA-4100R, no field amplifier is required.
With a catalytic sensor, the DIP switches and jumper settings should be set as shown below.
NOTE: Switch 1, position 4 can be put in the OFF position to give extra gain for ppm and low reactive
sensor types.
3.4.2 Two-wire 4-20mA Loop Powered Sensor & Transmitter
This diagram shows how to connect a two-wire 4-20mA loop powered sensor & transmitter to the GTA-4100R.
