AI250: Analog Input Module

- 4 Channels Programmable Analog Input

- 2 Channels Digital Input (Totalizer or Rate)

- 2 Channels Digital Output

- Support PoE Power Supply

- Support Protocol MODBUS TCP/IP

            Analog Input Module AI250 This device supports 4 analog input channels, 2 digital input channels, and 2 digital output channels. It is controlled by sending commands via the Ethernet port using the MODBUS TCP/IP protocol, enabling the use of a computer or PLC to programmatically read values and control the inputs and outputs.

            Analog Input For the AI250, the input signal can be selected from options such as 4-20 mA, 0-150 mVDC, 0-5 VDC, 0-10 VDC, or thermocouple.

            Digital Input It can accept Logic, Counter, and Rate signals. For Logic signals, it indicates an “ON” or “OFF” state; for Counter signals, it displays the totalized value of input pulses (such as the totalized volume or flow rate).

Connection to a computer or PLC via Ethernet or the Internet.
