2706-A21J

The Allen-Bradley 2706-A21J terminal is a Dataliner DL10 series industrial display terminal. The DL10 series includes compact 1-line, 2-line, and 4-line displays. DL10 units display alphanumeric messages in response to the serial ASCII data received from a host device. The host can be a master DL20 display, computer, or a programmable controller. DL10 units can be configured for the slave operating mode or the terminal operating mode. In slave mode, the DL10 unit receives data from a DL20 display. In terminal mode, the DL10 unit receives messages from a computer or programmable controller. The RS-232 port can be used for single-device serial connectivity and the RS-422 port can be used for multi-drop serial connectivity. The character height on DL10 displays varies from 0.49 to 0.59 inches. The viewing distance for the display is 27 feet. The operating voltage can be 120 or 240 Volts AC.

The 2706-A21J terminal is a 2-line display and can display up to20 text characters. The display technology is a blue-green VFD (Vacuum Fluorescent Display) 5 x 7 dot matrix. The dimensions of the display are 4.4 x 14.4 x 3.25 inches. Message memory is not available on the unit. The display accepts ASCII input. Communication interfaces on the unit include the RS-232 and RS-422 interfaces. The supported baud rates are 300, 1200, and 9600 baud. The 2706-A21J terminal operates at 120 Volts AC (±10%) at 60 Hertz. The maximum power consumption is 10 VA. The operating temperature range is from 0 to 50 degrees Celsius. The enclosure of the 2706-A21J terminal is the NEMA type 12 or 13 enclosure and it is designed for panel mounting.
