Description:
UT-901 is widely applicable for industrial automation, process control, central monitor station, Water Conservancy, warehouse surveillance, petrol field monitor, mine machinery, stage equip. Power distribution, railway, access, car parking, etc. Who needs remote acquire data and proceed application.
UT-901 comply with standard RS-232/422/485, Convert RF signal to balance differential RS-232 or RS-485/422, with built-in Transient Voltage Surging protection: TVS. Highly reliable in suppress lightning, 600W protection for each line for surging and lightning. RS-232 side as Db9 male; RS-422/485 side as binding post Zero-delay auto-transmission, delicate auto-control data stream I/O without RTS/DTR needed, jump wire setup as well Plug and plug, compilable to common software.
RF transceiver, developed by self-owned R&D power, Industrial grade, MODBUS, ASCII protocol supported, P2P, Point to Multi-P working mode, high-grade protection for interference, signal, easy to use, highly reliability with very reasonable price.
