The H2U-2DA Analog output block is an industrial control system device that provides two output channels for voltage (0-10V DC; 0-5V DC) or current (4-20mA DC). The analog output can be selected in voltage or current mode.

The range of analog input is 0-10V DC, 0-5V DC (external load resistance 2k-1MΩ) and 4 to 20mA DC (external load resistance 400Ω or less). The device has a 12-bit binary resolution for digital output and the conversion time for one channel is 4ms.

To isolate the analog input area from the PLC, the device uses photocouplers, and the power supply is isolated from the analog input area using a DC/DC converter. However, the channels are not insulated from each other.

The device can be powered using either DC5V/30mA (internal power supplied from the main unit) or DC24V/85mA (internal power supplied from the main unit). It occupies 8 input or output points and can be either inputs or outputs. The H2U-2DA Analog output block is compatible with H2U Plc (conversion blocks are needed) and weighs 0.2kg.

Overall, the H2U-2DA Analog output block is a versatile and accurate device that can be used in various industrial control systems.
