Product Descriptions

E821-DTU (2I2-400SL) is a remote control product that supports analog tracking and control acquisition. It supports wireless Modbus RTU protocol in control acquisition mode. This product is highly user-friendly, and users can easily and quickly integrate it into their own system to achieve remote control based on 433MHz wireless. The analog output of the receiving end can follow the analog input of the sending end, configured as bidirectional follow-up, and the analog output of the sending end can follow the analog input of the receiving end.

Product Features

Supports 2 analog inputs, default current detection;

Supports 2 analog outputs, default current output;

Support remote transmission of analog data through 433MHz wireless channels;

Support analog quantity following and control acquisition;

Supports four working modes: follow transmit, follow receive, control acquisition, and configuration mode; Support bidirectional following mode;

Support non local Modbus address forwarding function;

The control acquisition mode adopts Modbus RTU protocol for data processing:

Support Reset touch button, long press for 5 seconds to configure device address and restore factory settings:

Built in watchdog, with high reliability;

Three dual color indicator lights display the working status:

The power supply has good functions such as overcurrent, overvoltage, and anti reverse connection. When the equipment is well grounded, the input end of the power supply can withstand level 3 surge impulse (common mode ± 2000V, differential mode ± 1000V), level 3 pulse group interference (common mode ± 2000V, differential mode ± 1000V), and level 4 electrostatic interference (air discharge ± 15kV, contact discharge ± 8kV). 

When the equipment is well grounded, the 485 communication signal port can withstand level 3 surge impulse (common mode ± 2000V, differential mode ± 1000V), level 3 pulse group interference (common mode ± 2000V, differential mode ± 1000V), and level 4 electrostatic interference (air discharge ± 8kV). 15kV, contact discharge (8kV).
