Regulators And Indicators HD 9022
The microprocessor-controlled 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÷1V, 0÷10V 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.

Regulators And Indicators DO 9404
The dual regulating indicator DO 9404 is a microprocessor-controlled panel instrument with LED 96x96, with thresholds and alarms that may be programmed and configured by the user. In the two input channels it accepts signals coming from two distinct transmitters or from a double transmitter. The transmitters may be passive with 2 wires or active with 3 wires, in voltage 0-1 V, 0-5 V, 0-10 V or current 0-20 mA; 4-20 mA.
For both input channels the configuration possibility is always present in the instrument, no extra cards are needed.The choice of configurations for the input signals is made on the keyboard located on the front of the instrument.
The DO 9404 is provided with a serial output RS232C, the baud rate may be configured by means of the keyboard, the control is bi-directional and the output connector is a SUB D female 9-pole connector.
The instrument dimensions are in accordance with DIN 45700, 96x96 mm, depth 120 mm. The operating mode of the DO 9404 is chosen according to the application, configuring the instrument with the keyboard. It is possible to configure the instrument on the field with maximum simplicity to adapt it to changes in the process requirements.
The configuration possibility concerns the inputs, the extent of the scales, the set points, the alarms and the baud rate.
