B&B Electronics RT12-4444-9T-W20, RT12-0044-ZP-12 Power 10.5~28 Vdc, Data Activity LED Indicators

Power: 10.5~28 Vdc

Most DC power supplies rated from 10.5 to 28 Vdc @ 1000mA, will work with the RT12-4444-9T-W20. Do not use a power supply rated less than 1000mA. Doing so may cause the RT12-4444-9T-W20 to continuously reset. Make sure that the power supply voltage is maintained between the programmable HIGH and LOW supply voltage limits or an alarm may occur. If a rechargeable battery is used or if you are supplying voltage to a sensor using the same power used to power the RT12-4444-9T- W20, then the input voltage will need to be adjusted to the proper voltage to maintain respective equipment. Never exceed 28 Vdc. Damage by overheating to the controller will occur causing the system to malfunction.

Data Activity LED Indicators

The RT12-4444-9T-W20 RTU is equipment with four LED indicators. The RED/GREEN pair labeled “SERIAL”, indicate data transmit and data received. The RED LED will blink when data is being transmitted The GREEN LED will blink any time data is received, this is true for the MASTER and SLAVE.

Link/Sanity LED Indicators

The yellow LED indicator labeled “Status” indicates proper system operation. The second yellow LED indicator, labeled “Error”, will flash any time an alarm is programmed and the respective alarm is active.

Serial RS-232 Interface

Used to configure the RTU. See “Software Setup”.
