Versatile and Rack-Mountable
The GPX-32 is a universal interface designed to support 32 parallel channels of analog, status (via opto-isolated) and control (via relay contacts) per unit. The GPX-32 translates the General Purpose Input and Output (“GPI/GPO”) channels into TCP/Ethernet data streams for processing by the Axess software. Any number of GPX-32 units can be deployed with a single Axess system allowing for almost unlimited GPIO expandability. As the GPX-32 is connected via Ethernet it can be installed either locally or remotely to the host Axess system for flexible deployment. The GPX-32 is a “passive” device, which means it simply relays information from devices (e.g., temperature sensors, door alarms and light switches). The GPX-32 includes built-in temperature/humidity, mains and DC voltage monitoring with both 110/240AC and 20-60VDC operation possible.
Punch Down Panel Interface
The PDP or Punch Down Panel, is used to facilitate connection of passive peripheral equipment to the GPX-32 interface. The unit is comprised of 4 cables, 2 x SCSI 50pin and 2 x SCSI 68pin, which interconnect between the GPX-32 and the wiring interface. The PDP has PCB mounted 110 blocks, SCSI connectors and jumpers. The PCB is mounted on a 2RU metal frame to allow for easy mounting in a standard 19″ EIA rack.
