Pentair Announces New Point Four™ RIU3 Water Remote Monitor/Controller

Pentair Aquatic Eco-Systems has announced the release of their new Point Four RIU3 (Next Generation Remote Interface Unit), which offers a host of features suited to its customers’ detailed requirements for continuous monitoring and control of water parameters.

According to Pentair, 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 recirculating aquaculture 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 that can be set up 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 set up 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 four-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.
