main features

The EDA9060A module can be widely used in various industrial measurement and control systems. It can receive its digital input from the main computer, main controller, etc. through the RS-485 interface, convert it into relay contact output signals, and control AC contactors, switches, etc; And return the switch status and other switch input signals to the computer.

The communication interface of EDA9060A module is RS-485 interface, the power supply is DC10-24V, the communication protocol is ASCII code, hexadecimal LC-02, MODBUS-RTU protocol can be configured and selected; Its functions and technical indicators are as follows:

●Switch input:4-channel input, passive null contact input, or logic level 0:0~+0.5V or short circuit, logic level 1:+ 3V~+30V or open circuit. The input signal is isolated from the power supply ground, with an isolation voltage of 1000VDC.

●Switching output:4-channel relay output, two sets of normally open 2 contacts, and two sets of normally open normally closed 3 contacts. The output contact capacity is 8A 125VAC (5A250VAC 5A30VDC).

Each switch output can be set in two ways: level or pulse; The pulse width during pulse output can be set to 100-20000mS;

RS-485 network: Up to 32 EDA series modules can be hung on the same 485 bus, but by using RS-485 repeaters, up to 256 modules can be connected to the same network, with a maximum communication distance of 1200m.
