Product Usage Instructions
Analog Mode
The transmitter can be connected to a PLC or instruments BC 7335 – BC 7635
– BC 7635.010 or BC 7687 – BC 6587 which provide the Vdc power supply,
measuring values, two set points, and alarms. The digital input can place the
current loop on hold.
Digital Mode
In digital mode, the transmitter acts as a slave device interrogated by a
master device using protocol B&C (ASCII) or Modbus (function 03).
PH 3436
pH / ORP transmitter 4-20 mA and RS485
The transmitter can be configured for the measurement of pH or ORP and it can
also work with the antimony pH electrodes. The measured values, along with
support and instruction messages, are also visualized on an alphanumeric
display. The transmitter displays the temperature value measured by a Pt100
and performs the manual/automatic compensation (pH only). The extractable
terminal blocks and DIN rail mounting make easy maintenance and installation
in the field.
