CRIUS®4.0
Part of our range of controllers, the CRIUS®4.0 is the top of the range of the Pi controllers and offers more sensor connections, more functionality and more flexibility, with a color display and an optional built in 3G/4G modem.
The CRIUS®4.0 is a competitively-priced, top-tier instrument controller. Optional communications packages allow for Profibus, Modbus ASCII, Modbus RTU, Modbus TCP and others.
Renowned for its capability, flexibility and its intuitive user interface the CRIUS®4.0 is an extremely capable process controller and remote access internet gateway.
The CRIUS®4.0 comes equipped with the capability to connect up to four sensors of any type with suitable analogue outputs and relays. Four sensors not enough? Just connect up to 4 CRIUS®4.0 together, all using the same display and communications.
Equipped with data-logging as standard and multiple optional PID loops, the CRIUS®4.0 is an extremely capable controller, capable of controlling elaborate water treatment processes at a highly-competitive price in relation to other industry controllers.
With all users having their own log on credentials, and with three levels of instrument and remote access security, you can safely and confidently use the CRIUS®4.0 and all of its superior functionality.
- Multi-parameter – lower cost of ownership
- Onboard PID and other controls – improves control
- Onboard datalogging
- Remote Access via MQTT – control, monitor and make changes to your analyzer from anywhere in the world
- Industry leading automatic sensor cleaning options – lower maintenance costs
Almost any measurement or control application is suitable for the CRIUS®4.0 including; disinfection control in a variety of industries, coagulation control in the drinking water industry, aeration control in wastewater and many more.
- Up to 16 sensor inputs
- Up to 32 outputs
- Up to 32 relays
- Up to 32 digital inputs
- Unlimited PID loops
- Remote access (MQTT)
- Multiple digital comms options
Please choose the sensors of interest from the measurement drop down menu. Up to 16 of these sensors can be mixed and matched on a CRIUS®4.0.
