- Introduction of IOT Cellular Modem
ZHC4921 is an industrial-grade 4G RTU that provides 4 DI, 4 DO, 4
AI and 1 RS485 interface, supports local logic processing
operations, automatic acquisition and active reporting, Modbus
RTU/TCP adaptation, automatic calibration threshold reporting, dry
and wet node IO detection, and support one-to-one, many-to-one
network connection.
