N12B DIGITAL INDICATOR FOR SYNOPTIC PANELS
• Display of values from the register of devices with the
interface RS-485 with the MODBUS RTU/ASCII protocol:
– Master func%on - calling of the device appended to the
Modbus network,
– Slave func%on - display of stored values into the N12B meter
through another Master device of the Modbus network,
– Monitor func%on - intercep%on of values from the
defined register of the device appended to the Modbus
network,
• Linear individual characteris%c for displaying the transmiGed
value.
• 2 alarm outputs.
• Conversion of transmiGed value into a standardprogrammable current or voltage signal.
• Green or red, 5 or 4-digit readout field, digit height:14 mm
or 20 mm.
