9.3.4 Connection diagrams for externally powered hardware
9.3.4.1 Voltage-modulated signal with GSI127 galvanic separation unit
Applies to the later versions of the following transducers or transducer and signal conditioner
systems:
• TQ4xx + IQS45x + GSI127 galvanic separation unit.
Notes
1- Switch Sw1 is open to allow voltage-modulated signals to be processed.
The Signal Transmission Mode field has to be set to the Voltage option.
2- The operator must connect an external power supply to terminals “24 VDC +” and
“24 VDC −” of the GSI127 galvanic separation unit.
3- The sensor power supply is always set to −27.2 V.
NOTE: More detailed information on connecting equipment to an electronic monitoring
system can be found in the project-specific wiring diagram delivered with the
system or by referring to the electrical connections (wiring diagrams) section of the
appropriate sensors and signal conditioners installation manual.
