Inert Gas Control Relay Outputs

Connections from the Inert Gas Control relay contacts to a Neutronics Inc. Inert Gas Control
solenoid valve are made at terminal block TB2 on the rear of the analyzer chassis, for stand-alone
control of Oxygen in a process vessel or stream. They may be connected to other user-supplied
process control devices in parallel, depending on the application needs. The Inert Gas Control
relay contacts are voltage-free Form C relay contacts, SPDT, 5A@250VAC, 5A@30VDC. Be
certain to match the terminal pins against the terminal ID label on the top of the analyzer chassis.
Refer to Appendix F – reference drawings.
2.1.3.5

Fault Relay Outputs

Connections from the Fault relay contacts to the user's process control equipment are made at
terminal block TB2 on the rear of the analyzer chassis. The Fault relay contacts are voltage-free
Form B relay contacts, SPST, 5A@250VAC, 5A@30VDC. Be certain to match the terminal pins
against the terminal ID label on the top of the analyzer chassis. Refer to Appendix F – reference
drawings.
2.1.3.6

Remote Calibration Relay Outputs

Connections from the Remote Calibration relay contacts to a Neutronics-supplied Calibration
solenoid valve are made at terminal block TB2 on the rear of the analyzer chassis. The Remote
Calibration relay contacts are voltage-free Form C relay contacts, SPDT, 5A@250VAC,
5A@30VDC. Be certain to match the terminal pins against the terminal ID label on the top of the
analyzer chassis. Refer to Appendix F – reference drawings.
