Installation in any hazardous area must comply with all applicable restrictions, requirements, and guidelines for said hazardous areas. It is the end user customer’s final decision to ensure that the PROTECTOR P8XA System Controller is suitable for the intended use. -
Page 6: Overview
PROTECTOR P8XA User’s Manual, Revision 1.0 OVERVIEW The GDS Corp PROTECTOR P8XA System Controller is designed to provide power for and monitor gas values from one to eight wired gas monitors via industry-standard 4-20mA analog inputs. The PROTECTOR P8XA features a 4.3” diagonal high-contrast, sunlight-readable color LCD display that provides immediate feedback on alarm status and input values. -
Page 7: Installation
POWER INPUT CONNECTION When using the optional AC power supply, the PROTECTOR P8XA is designed to operate on a clean source of 110VAC / 60 HZ or 220VAC / 50 Hz power. Up to 40 watts of power is available at the AUX PWR outputs. -

PROTECTOR P8XA User’s Manual, Revision 1.0 ANALOG INPUT CONNECTIONS The eight analog input terminals are located along the top of the ANALOG INPUT MODULE. Each input covers the full range of 0-20mA, allowing the P8XA to recognize problems with remote sensors that use “less than 4.0 mA”... -
Page 12: Figure 3-6: Example Sensor Connection (Channel 1)
PROTECTOR P8XA User’s Manual, Revision 1.0 Most remote sensors require a source of +24VDC to operate. The P8XA provides four terminals for +24V along the bottom of the PCB and an additional three in the AUX POWER terminals located at the upper right side of the main PCB. -
Page 13: Figure 3-7: Local Analog Output Wiring
Figure 3-7: Local Analog Output Wiring RELAY OUTPUT CONNECTIONS 1-4 The PROTECTOR P8XA has four dry-contact five-amp (5A) alarm relays that are wired to provide NORMALLY OPEN and NORMALLY CLOSED contacts. When not energized, the COMMON terminal is connected to the NORMALLY CLOSED contact. When the relay is energized, the COMMON terminal is connected to the NORMALLY OPEN terminal. -

RELAY OUTPUT CONNECTIONS 5-6 The PROTECTOR P8XA has two wet-contact alarm relays that are wired to provide switched +24V to local strobes or piezo buzzers. Output current is limited to 500 mA (12 watts) per output. -
Page 15: Figure 3-10: Remote Alarm Ack Interface
PROTECTOR P8XA User’s Manual, Revision 1.0 REMOTE ACKNOWLEDGE The PROTECTOR P8XA supports a remote Alarm Acknowledge pushbutton that can be installed up to 100 ft from the enclosure. The button should be MOMENTARY, NORMALLY OPEN (see diagram). In electrically noisy environments, GDS Corp recommends running shielded wiring in metallic conduit for maximum reliability. -
Page 16: Figure 3-11: Isolated Analog Outputs
PROTECTOR P8XA User’s Manual, Revision 1.0 ISOLATED 4-20MA OUTPUTS The PROTECTOR P8XA can be configured to include an optional four-channel 4-20mA isolated analog output module. If installed, each output will mirror the incoming 4-20mA signal on corresponding channels 1, 2, 3 and 4. The four-channel output module, if installed, is located on the lower right side of the enclosure. -
Page 17: Programming & Setup
Channels are programmed using the CHANNEL CONFIGURATION MENU, while global settings for the entire controller are programmed using the SYSTEM SETUP MENU detailed later in this chapter. After power-up, the PROTECTOR P8XA will display a start-up screen and then switch to the Primary Display. PRIMARY DISPLAY After power-up, the PRIMARY DISPLAY screen is activated. -
