The 1770-T1 is an industrial terminal system manufactured by Allen-Bradley. The Allen-Bradley 1770-T1 industrial terminal is part of Series B of the Allen-Bradley industrial terminals. The Allen-Bradley 1770-T1 industrial terminal features a 9-inch diagonal CRT display screen, a keyboard for control, and a graphic keytop overlay. The Allen-Bradley 1770-T1 industrial terminal is applicable in all PLC-2 family processors. The Allen-Bradley 1770-T1 industrial terminal CRT display screen is capable of displaying 80 characters per line on up to 24 lines. The Allen-Bradley 1770-T1 industrial terminal keyboard consists of a sealed touchpad and it entails PROMS which provide the keyboard with the instruction set that is used in programming the PLC-2 processor. When the Allen-Bradley 1770-T1 industrial terminal is not being operated, mount the front cover to secure the CRT screen and the keyboard.

When installing the 1770-T1 industrial terminal, users should mount the keyboard and keytop overlay and choose the correct AC input voltage. The Allen-Bradley 1770-T1 industrial terminal is designed for 120 Volts AC and 60 Hertz applications. The switches located on the main logic board are used to initialize the power-up selection for the communication rate and the line frequency for Channels B and C. The 1770-T1 industrial terminal can be connected to peripheral components, modems, and processors via Channels B and C. When the 1770-T1 industrial terminal is in alphanumeric mode, it can be used for reporting generation with the PLC-2 processor. Multiple 1770-T1 industrial terminals can be configured locally or up to 5000 feet apart. The 1770-T1 industrial terminal normally does a diagnostic test during powerup. The 1770-T1 industrial terminal will display a fault message in case of an error and sound the fault tone continuously until the problem is fixed. When a fault message appears, turn off the Allen-Bradley 1770-T1 industrial terminal for a short period of time, then turn it on again. When the communication fault message reappears, turn the power switch off and disconnect the cable from Channel B’s socket. Then reconnect the cable and turn the Allen-Bradley 1770-T1 industrial terminal power switch back on.
