The Control unit is a PNP type with Ethernet connectivity, designed to operate at 24 VDC. It has a total of 32 controllable I/O points, with 16 inputs and 16 outputs. When expanded, it can support a maximum of 384 points.The programming method/control method used is relay symbol/cyclic operation. The input operating voltage range is between 21.6 to 26.4 VDC, while the output operating load voltage range is also between 21.6 to 26.4 VDC.For communication, the control unit features an Ethernet interface that supports both 100BASE-TX and 10BASE-T protocols (TCP/IP, UDP). It also supports MODBUS RTU and RS-232C communication via a three-wire system on one channel (not insulated). Additionally, it has a USB2.0 Full speed (USB mini B type) interface and uses MIL connectors for connection.One notable feature of this control unit is its built-in SD memory card function, allowing for convenient storage and retrieval of data.Overall, this control unit offers reliable performance and versatile connectivity options for various industrial applications.
