Overview

The SRTU is the answer for many low point count point-to-point and point-to-multi-point SCADA applications.

The SRTU has been designed from the ground up to fit small to medium I/O requirements. It is a board level product that can be integrated into new designs, as well as an ideal upgrade for out of date existing RTUs. Designed with simplicity in mind, the SRTU is based on a single chip 8-bit microprocessor, and uses the latest in wafer scale integration technology to minimize the part count, increasing reliability.

The SRTU is designed as an industrial product with industrial temperature rated parts. It has two RS-232/RS-485 communication ports. One port can be interfaced to virtually any radio, and has configurable baud rates, and key on / key off delays. The other port is for configuration, and simple diagnostics. It has 6 digital inputs, 2 pulse inputs (with built-in 32 bit accumulator), 6 digital outputs, (2 are 12 amp relays), and 2 each 12-bit analog inputs. An optional expansion module adds 16 digital inputs, 16 digital outputs, 4 12-bit analog inputs, and 4 12-bit analog outputs.
