Sensors and peripheral equipment

Remote Terminal Units (RTU)These are small units with several inputs and outputs, installed in the field at a distance of a few km from the controller. The unit is connected locally to the elements (solenoids, meters, sensors etc.), it is constantly in communication with the controller receiving operational command and transferring data back to the controller. There are 3 types of RTU:The system consists of a CRTU adapter inserted into the controller, a 3 wire single cable that can be up to 6 km long along which the CRTU units are installed. A combination of units with a total of up to 128 outputs can be installed along the cable. Two such cables can be installed on one controller.There are two basic CRTU modelsCable RTU (CRTU)The system consists of a CRTU adapter inserted into the controller, a 3 wire single cable that can be up to 6 km long along which the CRTU units are installed.
