The 149992-01 is a core component of the 3500 Machinery Protection System, known as the 16-Channel Relay Module. This module is designed to perform logic switching based on alarm statuses defined by other monitor modules in the rack.
Full-Height Module
Includes "Alarm Drive Logic"
Can Use Alarming Inputs
The 16-Channel Relay Module is a full-height module that provides 16 relay outputs. Any number of 16-Channel Relay Modules can be placed in any of the slots to the right of the Rack Interface Module. Each output of the 16 Channel Relay Module can be independently programmed to perform needed voting logic. Each relay utilized on the 16-Channel Relay Module includes "Alarm Drive Logic". The Alarm Drive Logic is programmed using AND and OR logic, and can utilize alarming inputs (alerts and dangers), Not-OK, or individual PPLs from any monitor channel or any combination of monitor channels in the rack. This Alarm Drive Logic is programmed using the 3500 Rack Configuration Software to meet the specific needs of the application.

Oil & Gas
Used for centrifugal compressor trains on offshore platforms or onshore plants. Relays trigger emergency shutdowns (ESD) when excessive shaft vibration is detected to prevent catastrophic explosions or leaks.
Power Generation
Monitoring axial displacement in gas or steam turbines. Relays act as the last line of defense, forcing a fuel shut-off before a rotor-stator collision occurs.
Petrochemical & Refining
Managing shutdown logic for large extruders or critical process pumps. Utilizes 16-channel flexibility to execute combined fault logic for vibration, displacement, and temperature.
Steel & Metallurgy
Controlling blast furnace blowers. Relays promptly execute protection via the control system when cooling fails or mechanical vibration exceeds limits to protect core assets.
Mining & Minerals
Protecting large ball mills or SAG mills. Relays convert vibration status into dry contact signals to directly trip high-power motor circuit breakers.
Air Separation
Controlling air separation compressors in liquid oxygen/nitrogen plants. Relays provide strict mechanical protection logic during complex startup and operational phases.
Strictly adhere to the relay contact ratings (typically 5A @ 24Vdc/120Vac). Never drive high-power motors or heavy actuators directly. Use interposing relays to avoid damaging the internal precision contacts.Carefully verify "Voting Logic" (e.g., 1-out-of-1, 2-out-of-2) in the software. Incorrect settings may cause failure to trip (dangerous failure) or nuisance trips. Logic simulation tests are recommended before startup.
It essentially acts as a switch, turning high-power devices on or off in response to a low-power control signal from the microcontroller. Each channel on the relay module can be independently controlled, enabling simultaneous control of multiple devices.
What is the purpose of a relay module?
A relay module is a switching device, the control circuit that operates with low-power signals. It enables a low-power supply circuit to switch on or regulate a high-power supply circuit without integrating it with the same circuit or electrical appliance.
What is a 16A relay?
Description. The RM-16A relay module is used to enable/disable electrical devices. Thanks to its small dimensions, it can be mounted in a flush-mounting box, or where there is a need to control a receiver with a maximum load of 16 A. Example use: • Remote relay for voltage devices.
