Quick Detail

Description

The 3500/32M 149986-02 4-Channel Relay Control Module provides four programmable relay outputs for industrial automation racks. Each relay of the 3500/32M 149986-02 is single-pole, double-throw (SPDT), epoxy-sealed, and includes a 250 Vrms arc suppressor. Relays are switch-selectable for Normally Deenergized or Normally Energized operation with contact life of 100,000 cycles @ 5 A, 24 Vdc or 240 Vac. The 3500/32M 149986-02 consumes 5.8 W, fits one full-height front slot, and operates from -30°C to +65°C, storing from -40°C to +85°C with 95% non-condensing humidity. LEDs indicate OK, TX/RX communication, and CH ALARM status. DC switching supports 100 mA minimum up to 2 A maximum, 0–125 Vdc; AC switching up to 2 A and 250 Vac. The 3500/32M 149986-02 integrates with Bently Nevada 3500 Configuration Software to program alarm drive logic using AND/OR logic for automated voting, alert, and danger responses, enabling precise control of critical industrial processes.

Applications

Program Relay Outputs for Alarm Logic

The 3500/32M 149986-02 allows automated configuration of AND/OR alarm logic for each of the four channels. Each relay can use alert, danger, Not-OK, or individual PPL inputs to control machinery alarms with precise 100 mA–2 A DC and up to 2 A AC switching.

Control Rack Trip Multiply and Reset Functions

With the 3500/32M 149986-02, operators can automatically execute Trip Multiply, Alarm Inhibit, and Rack Reset actions, using relays rated for 100,000 cycles and DC voltages up to 125 V, ensuring real-time automated rack control.

Integrate Multiple Modules in Automation Racks

The 3500/32M 149986-02 occupies one full-height front slot, allowing multiple modules to be added to the right of a TDI module. Automated racks can coordinate four-channel relay outputs across several modules, using TX/RX LED communication to confirm signal integrity.

Manage Critical Industrial Processes

Using epoxy-sealed SPDT relays with 250 Vrms arc suppressors, the 3500/32M 149986-02 provides reliable automated switching for motors, pumps, or compressors within industrial control systems under -30°C to +65°C operating temperatures.

Specifications

Competitive Advantage

High-Power Relay Switching Capability

The 3500/32M 149986-02 switches DC currents up to 2 A @ 30 Vdc and AC currents up to 2 A @ 250 Vac, enabling automated control of high-current industrial devices without additional external relays.

Long Relay Life for Continuous Automation

With 100,000 cycles at 5 A, 24 Vdc or 240 Vac, the 3500/32M 149986-02 provides long-term operation for automated alarms and process control, reducing maintenance frequency.

Immediate Rack Status Feedback via LEDs

Front panel OK, TX/RX, and CH ALARM LEDs on the 3500/32M 149986-02 allow operators to visually confirm relay function, communications, and alarm states, supporting automated troubleshooting and maintenance.

Operate in Harsh Industrial Environments

The 3500/32M 149986-02 functions across -30°C to +65°C, tolerates up to 95% non-condensing humidity, and stores safely from -40°C to +85°C, enabling automated relay control in extreme industrial conditions.
