The 2500 Digital Controller provides up to 4 signal inputs from a variety of different sensor types, 2 controlling analogue outputs for pump or valve control, and 1 retransmission analogue output for sending to a data recorder.
As standard the 2500 digital panel controller instrument has 4 relay outputs built-in for use with alarm indication circuits
The 2500 digital process controller has three 5 digit LED displays on the front panel for displaying the process variable, set-point values and control output value. There are also bar-graph indicators for control output percentage and deviation from set-point
All set-up functions can be configured via the 6 key soft-touch keypad which is protected to IP54 against with a option for a IP65 protective cover
Maths functions such as the differential of 2 input signals can be programmed as the process variable to be controlled which is useful for applications such as measuring the level of liquid in a tank and borehole which is not vented to atmospheric pressure.
