Do not paint transmitter or sensor assembly. Do not operate the PROTECTOR12 if its enclosure is damaged or cracked or has missing components. Make sure the cover, internal PCB’s and field wiring are securely in place before applying power. -
Page 6: Overview
Protector12 User’s Manual, Revision 1.0 2 OVERVIEW The GDS Corp PROTECTOR12 System Controller is designed to provide power for and monitor signals from up to eight or twelve industry-standard 4-20mA devices, including all GDS Corp gas monitors, sample draw monitors and process monitors. -
Page 7: Installation
3 INSTALLATION DC POWER INPUT CONNECTION The PROTECTOR12 is designed to operate on a clean source of +12VDC to +30VDC. Voltage spikes above +30V or below +12V can permanently damage the unit. When using a DC source, connect the (+) and (-) wiring to the Main Terminal Board as shown below. Depending on the number of sensors, there may be one or two Sensor Boards that will be pre-wired to the DC terminals. -

Protector12 User’s Manual, Revision 1.0 AC POWER INPUT CONNECTION The PROTECTOR12 can be ordered with an internal AC power supply as shown below. In this case, a source of 110VAC or 220VAC (50/60 Hz) should be connected to the power supply as shown below. -
Page 9: Figure 3-3: Connecting Sensors 1-2-3-4 To Main Terminal Board
Protector12 User’s Manual, Revision 1.0 CONNECTING SENSORS The PROTECTOR12 is designed to work with two and three-wire sensors that utilize an external source of excitation voltage and return a calibrated 4-20mA analog signal. Three-wire sensors are wired as shown below. Sensors #1 through #4 connect to the Main Terminal Board; sensors #5 to #8 connect to Sensor Board #1, and sensors #9 through #12 connect to Sensor Board #2. -
