The Point Four RIU3 (Next Generation Remote Interface Unit) offers a host of features suited to our customers’ detailed requirements for continuous monitoring & control of water parameters.
The RIU3 functions as either a stand-alone field mounted transmitter/controller, or can be daisy chained to create a multi-linked network connection, supporting up to 99 units. An unlimited amount of multi-linked network connections can be made allowing for a scalable system from small hatchery operations to large RAS systems. Users can collect, manipulate and control all of their data via the Point Four RIU3 Controller, Point Four LC Touch Controller or using the Point Four Sync HMI Software (windows based).
The RIU3 will accept multiple input types (4-20mA/ 0 -5 V/ Modbus RS485) and contains 2 SPDT 4amp relays which can be setup for up to six control blocks. Control blocks are configured directly via the keypad, or through a PC using a computer connection cable; allowing users to setup local control, configure alarm conditions or even perform PID function. A key feature of the RIU3 is tank side probe calibration, which is easily performed using the weatherproof 4 button keypad. Probe calibration can now be done by just one operator, allowing the user to service the probe and adjust values all at the same probe location.
