The 3500/32-01-01 is a 4-channel relay module. Its core function is to receive alarm signals from other monitoring modules within the module and, according to preset logic, drive external interlocking circuits through the "open/close" of physical contacts to achieve automatic shutdown or alarm.
Physical alarm output
Supports complex alarm logic
The module continuously performs self-checks
The 4-Channel Relay Module is a full-height module that provides four relay outputs. Any number of 4-Channel Relay Modules can be placed in any of the slots to the right of the Transient Data Interface Module. Each output of the 4 Channel Relay Module can be independently programmed to perform voting logic. Each relay utilized on the 4-Channel Relay Module includes Alarm Drive Logic. Programming for the Alarm Drive Logic uses AND and OR logic, and can use alarming inputs (Alert and Danger statuses), Not- OK, or individual PPLs from any monitor channel or any combination of monitor channels in the rack.

Natural Gas Transmission
Trigger relays to close gas supply valves immediately when severe vibration occurs in compressor station units.
Thermal Power Generation
Drive trip circuits for emergency shutdown when steam turbine axial displacement is excessive.
Petrochemical Refining
Monitor critical reciprocating compressors and force shutdown upon detecting impact signals to prevent casing rupture.
Centrifuge Manufacturing
Cut off motor power to protect personnel when the imbalance of high-speed centrifuges exceeds limits.
Steel Production
Monitor blast furnace blower main bearings and trigger interlock protection during high-temperature alarms caused by lubrication failure.
Water Treatment
Automatically stop pump operation when severe vibration occurs due to cavitation in large feedwater pumps.
When using the 3500/32-01-01 relay module, it is critical to ensure that the software logic matches the physical wiring and that the correct mode—Normally Energized (NE) or Normally De-energized (NDE)—is selected based on safety requirements. Before maintenance or replacement, always switch external control loops to manual or bypass and activate the Alarm Inhibit function to strictly prevent unplanned shutdowns caused by accidental contact transitions.
It is a 4-Channel Relay Module for the 3500 system, providing four programmable relay outputs to trigger external interlocks or shutdown systems based on alarm logic.
What is the primary use of 3500/32-01-01?
It is primarily used for machinery protection by closing or opening contacts to shut down equipment or send signals to control systems when vibration or displacement exceeds limits.
Are the four relays on 3500/32-01-01 independent?
Yes. Each relay can be independently programmed to operate based on different alarm inputs and logic (such as AND/OR logic).
What alarm logic does 3500/32-01-01 support?
It supports And and Or logic. For example, it can be configured to trigger only when both Channel 1 and Channel 2 are in alarm.
How to configure the 3500/32-01-01?
It is configured using the 3500 Rack Configuration Software by connecting through the 3500/22 TDI module.
