2289 is a Signal calculator
Two analog inputs
3-digit LED display
Version with a Pt100 input
Analog outputSignal calculator
Programmed via the user interface which consists of a 3-digit display and 3 function keys in the front panel.
Operates as a PID controller with an analog or a Pt100 input.
Functions include a manual / automatic controller, an analog calculator with a scale function on both inputs, a samplehold transmitter, a peak-hold transmitter, a delay transmitter, a signal limiter, averaging of noisy signals, monitoring of a signal’s slope, or an analog multiplexer.
The A and B inputs can be programmed to receive current signals in the range 0…20 mA (eg. 4…20 mA), or voltage signals in the range 0…10 VDC.
Input A is a linearized Pt100 with a 3-wire connection. Input B is an analog current / voltage input.
Digital inputs are jumper selectable NPN or PNP.
Analog standard current / voltage output of 0/4…20 mA / 0/2…10 VDC
