CRONOS®
Part of our controller range, the CRONOS® is the less capable, and therefore less expensive, cousin of the CRIUS®4.0.
The CRONOS® is a top-quality, low-cost transmitter designed to arm water treatment engineers with everything that they need from a transmitter, without any unnecessary hardware or firmware. With no frills, costs can be kept minimal, whilst optional communications packages allows for Profibus, Modbus ASCII, Modbus RTU, Modbus TCP, 4-20mA analogue outputs, and relays for alarms and control.
As standard the CRONOS® comes with the same interface and firmware as the world-leading CRIUS®4.0, with all the same capability just reduced, so less I/O (up to 2 sensors) and a grayscale display.
The CRONOS® is capable of controlling up to two sensors of any type with relevant analogue outputs and relays. With optional PID control, the CRONOS® is quite capable of controlling complex water treatment processes, all at a fractional cost of other controllers.
