S3000/S4000 RTU

The S3000/S4000 RTU is a full-featured Remote Terminal Unit for use in Micro-Comm control systems. It is a "smart" unit providing both programmability and interchangeability through a plug-in memory module. As an integrated component of a Supervisory Control and Data Acquisition System (SCADA), the S3000/S4000 provides input and output monitoring and control with simultaneous "distributed" (RTU to RTU) and "centralized" (CTU to RTU) control operations. Its universal communications interface can provide robust control and data transfer via radio, dedicated line, phone line, and fiber optic communication media.

The S3000 RTU is a reduced I/O version of the S4000 having 4 external analog inputs and 4 relay outputs.
