Zen RTU Remote Terminal Unit, ZEN-RTU

Type:  Remote Terminal Unit
Description:  Get 16 signals into your PLC or SCADA system! If you need to collate multiple signal input types and route them to your PLC or SCADA system, choose the Zen RTU. This flexible and powerful monitoring and control station has four digital inputs and an RS485 Modbus/RTU port. Additionally, it has an Ethernet port that can be selected as Modbus TCP, or EtherNet/IP (ODVA CONFORMANT) for connection to Logix Controllers, FactoryTalk View etc. The Zen RTU is available with 16 Isolated Universal Inputs and accepts Current, Voltage, RTD, TC, Frequency, Counter and more. An RTD-only, Non-isolated version can also be selected as a cost-effective option for multi-channel temperature applications where isolation is not required.
