Product Description

The G308A000 is the first of the G308 terminals from Red Lion, the display on this model is TFT rather than VGA. The main difference between the G308A000 terminal and the G303 and G306A/M terminals produced by Red Lion is not only the screen size which is 8.4 inches but the amount of onboard user memory available. The onboard user memory available for this model is eight megabytes of non-volatile flash memory compared to the standard four on the models up to this point. 

The power supply requirement needed to run this module without any difficulties is a direct current voltage of twenty-four with a rated power supply of twenty-four watts as well. Please note that it is likely that this unit may draw less than twenty-four watts depending upon the options chosen. It should also be noted that the power supply for the G308A000 model should be no more than six feet away to prevent the overuse of cabling between the operator interface and the power supply. 

Two ports are available on this device, a Comms and PGM port, each port is described as an RS232 port. Only one can be used for programming but both of them can be used for communication with a PLC (programmed logic controller). These ports can also function as either a master or slave protocol with any chosen G308 configuration. All of the connection types can be found in a table on page four of the G308A-E Model G308A Product Manual. 

The RS422/485 Comms ports can be used to connect the G308A000 to Allen Bradley DH485 communications but it should be noted that a standard DH485 cable should not be used to connect the port to any Allen Bradley equipment. 

Frequently Asked Questions about G308A000

What makes the G308A000 panel unique compared to the other G3 series HMIs?

One of the features of the G308A000 panel is its screen size. The screen size for this model is 8.4" with a slightly textured finish. One downside of the G308A000 panel is that it can only be used in indoor applications since the touchscreen can not be easily read in sunlight. Another unique feature of this panel is that there are seven programmable keys located along the left side of the touchscreen, which are also used to access and control the menu. 

What rating of power supply must be used with the G308A000 panel?

The G308A000 panel must use a SELV or Class 2 rating. These two ratings will provide isolation to the circuits from different types of potentially hazardous voltages generated by main power supplies due to singular faults. The SELV or safety extra-low voltage rating will help with voltages that are safe to touch when a single fault has occurred, as well as standard operating conditions. 

Reviews For G308A000

Internal Review

Most of the G3 HMIs can only use one specific CompactFlash card, but the G308A000 panel can have three different cards. The three CompactFlash cards are 64, 256, or 512 MB cards which are industrial grade with two million write cycles. The G308A000 panel is set apart from the other G3 series because of the CompactFlash cards and the larger analog touchscreen. - AX Control Tech
