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.Radio RTU AP (1 way RRTU)This system transmits a radio signal from the controller to a distance of up to 5 km (depending on the field conditions), the signal is received by the radio RTU and can open or close outputs. (This unit does not include inputs).The system consists of:Serial Transmitter (SRT): includes: 1W-RRTU adapter (located inside the controller), data cable, radio transceiver and an antenna.Field Units: includes:2 or 4 12 VDC latching outputs A lithium battery, 3.6 VDC which lasts under field conditions up to 2-3 years.The unit is enclosed in 100% water proof, epoxy molded housing.Each unit is loaded with its own "private" code number using a portable terminal.
