3.5 Connection of transmitter PC-3110 and accessorial transmitter PH-300T
A. Connect the GLASS point of transmitter PH-300T’s terminal to the electrode coaxial inner.
(Note: Remove the black conductive rubber); connect the REF point of transmitter
PH-300T’s terminal to the electrode coaxial shield.
B. See the two-wire distributing system and three-wire distributing system in the following
page.
C. Sign “PT-1000” on transmitter PH-300T’s terminal is the connector for automatic
temperature compensation probe, PT-1000, or applies a fixed temperature compensation
resistance.
D. The V+ and V- of transmitter PH-300T’s terminal respectively connect to DC12V+ and –
of the controller.
E. The S+ and S- on transmitter PH-300T’s terminal respectively connect to GLASS and REF
of the controller.
F. The I+ and I- on transmitter PH-300T’s terminal are output (4-20mA), which can connect
to devices that receive current signals.
(Note: The current output signal of this
transmitter is not insulating, and thus do not directly connect with a PLC!)
Note: Refer to the following table for proper fixed temperature compensation resistance
