- Spare 4-Channel Relay Control Module
- 3500/32M 4-Channel Relay Module
- The 4-Channel Relay Module is a full-height module that provides four relay outputs
The four-channel relay module is a full-height module providing four relay outputs. Any number of four-channel relay modules can be installed in any slot on the right side of the transient data interface module. Each output of the four-channel relay module is independently programmable to execute voting logic.
Each relay on the four-channel relay module contains alarm-driven logic. The alarm-driven logic is programmed using AND and OR logic and can use alarm inputs (alarm and danger states), abnormal states, or a single PPL from any monitoring channel or any combination of monitoring channels in the rack.
The 3500/32M 149986-02 Bently Nevada 4-Channel Relay Control Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The Bently Nevada 3500/32M four-channel relay module operates based on a digital logic drive mechanism. It receives alarm status signals in real time from other monitoring modules (such as displacement, vibration, speed, or temperature modules) via the backplane bus of the 3500 rack. The module's internal processor performs complex Boolean operations on these input signals according to the preset logic drive array (such as AND, OR, or 2oo3 voting logic) in the configuration software. Once the operation result meets the trigger condition, the module immediately drives its physical relay coil to actuate, outputting dry contact signals to the external control system (such as a PLC or DCS) through the closing or opening of the contacts, thereby achieving automatic shutdown or alarm protection of the mechanical equipment.
1. Automatic Shutdown: The most common application is as an automatic shutdown trigger. When vibration, position, or temperature monitors in the rack detect a "dangerous" condition, the 3500/32M sends a trip signal to the machine's control circuitry to prevent catastrophic failure.
2. Industrial Interlocks: Used to provide interlock signals for complex industrial processes, ensuring that equipment such as turbines, compressors, and pumps operate only when specific safety parameters are met.
3. Remote Alarms: Triggers external alarms, strobe lights, or SCADA alarms to notify operators of "alarm" or "abnormal" conditions.
4. Critical Industry Protection: Widely used in the oil and gas, power generation, and petrochemical industries where the reliability protection of rotating equipment is critical.
