RDP180 DIN-Rail Mounted PLC

The RDP180 is a unique "open architecture" rail-mounted PLC equipped with an ARM processor. Ideal for use in all industries, the RDP180 supports industry standard Modbus ASCII, RTU and TCP protocols. The RDP180 features limited onboard I/O for smaller applications. For larger applications, the RDP180 can be used in conjunction with an I/O device, such as the RIO128/RIO032, to provide distributed process automation over wide-area Wireless and Ethernet networks.

Programmed "on-the-fly" using the supplied ladder logic software and featuring local I/O (9 digital inputs, 2 digital outputs, and one analog input), an RS-232/RS-485 serial port and an Ethernet port, the RDP180 is suitable for just about any application. The RDP180 can be ordered with either an additional RS-232 serial port for I/O expansion or a modem for autodialer functionality.
