SIGNAL CONVERTER DIEHL ELECTRONIC ACCESSORY | DISPLAY AND CONTROL DEVICES_ _ The spectrum of applications primarily covers the transmission of instantaneous values and provides the basis for the display and/or recording of flow rates in pipes. The current output is also used for various control and monitoring tasks. ► Designed as snap-on housing for mounting rail ► 2-channel control options for compound meter: infrared reflex pulse transmitter (571), two-wire proximity switch to DIN 19234 (NAMUR) (572, 573) self-optimizing level, electronic counter module, mechanical compact ► Front-panel programming buttons for setting menu controlled functions ► Freely programmable input pulse values ► Filtered output signal 0/4 mA... 20 mA and 0/2 V ... 10 V ► 1 floating output (make contact, open collector) ► Electrically isolated measuring and supply circuits ► LC display for flow rate (m3/h or l/s); min./max. flow rate; meter reading; menu guidance ► M-Bus interface (option)

ELECTRONIC ACCESSORY | DISPLAY AND CONTROL DEVICES The microprocessor-controlled LCD universal signal converter converts the pulses from the volume measuring components in the water meters (main meters and submeters) to a dc current proportional to the flow rate (digital-analogue converter). The current amplitude is proportional to the instantaneous flow rate. The converter is also used for converting high-resolution pulses to decadic pulses (e.g. m3). The signal converter 520.11 is programmed via touch controls on the front panel. TECHNICAL DATA Supply voltage Temperature drift Storage temperature...
