HD9022 Microprocessor panel indicator and regulator 48x96, with thresholds that may be programmed and configured by the user. Resolution of the A/D converter: 0,1mV/digit - 2μA/digit. Input 0...20mA, 4...20mA, 0...V, 0...10Vdc, input 4-wire Pt100. One relay for output 1, one relay for output 2, one maximum and minimum alarm relay. Serial output RS232 C.
Power supply 24Vac/dc, on request 110...230Vac/dc.
Applications:
Typical applications are the display of signals sent by transmitters which may concern temperature, humidity, pressure, speed, capacity, level, force, etc., for the most varied industrial sectors, operating machines and automated systems.

The microprocessor control LED panel instrument HD 9022 is an indicator with alarm thresholds that may be programmed and configured by the user.

At input it accepts signals arriving from transmitters with 2 or 3 wires, 
in voltage 0÷ 1 V, 0÷ 1 0V or in
current 0÷20 mA, 4÷20 mA,
or Pt100 with 4 wires.

Configuration is always completely present in the instrument, no additional cards are required. 
 

The choice for the configuration of the input signals is made by means of the keyboard on the front of the instrument. 
The dimensions of the instrument are 96x48 mm with depth 145 mm in conformity with DIN 45700.
The mode of operation of the HD 9022 is chosen depending on the application, configuring the instrument with the keyboard. 
The instrument may also be reconfigured with absolute simplicity on the field in order to adapt it to changes in processing requirements.
The configuration involves the input, the scale range, the set point and the auxiliary outputs.

Characteristics
Set point configurable from -9999 to +19999.
Indication provided by red LED's with seven 1/2 inch segments.
Separate clamp for voltage input 0÷ 1/ 0÷ 10V, current input 0÷20 or 4÷20 mA and Pt100 input (-200÷ +800°C).
