[Introduction]：E830-DTU (2R2-433L) is a remote control product with switch follow and control acquisition functions. It supports 2 isolated switch inputs and 2 relay outputs. The communication interface adopts RS-485 interface (only used in configuration mode ); the wireless acquisition function supports the standard MODBUS RTU protocol. This product is highly easy to use and can be widely used in signal acquisition, monitoring and control of industrial field equipment.
