BENTLY 3500/62

Product introduction

The Bently Nevada 3500/62 is a versatile digital input/output module, designed to serve as the interface between the 3500 series machinery protection system and external control devices. It enables seamless communication between monitoring components (like vibration modules) and operational equipment (such as valves, pumps, or alarms), making it a critical link in industrial automation workflows.

Powered by the reliable 3500/15 106M1079-01 power supply module, the 3500/62 processes 16 digital inputs—capturing status signals from sensors or switches—and controls 16 relay outputs to trigger actions like shutdowns, alarms, or process adjustments. This bidirectional communication allows the 3500 system to both monitor external equipment status and respond to critical conditions detected by modules like the 3500/33-01-00.

As an integral part of the 3500 ecosystem, the 3500/62 integrates with signal conditioners such as the 3500/42M 140734-02 and configuration software 170180-01-00, enabling customized logic for specific industrial processes. Its rugged design ensures reliable operation in harsh environments, from refineries to power plants, where accurate digital control is essential for safety and efficiency.

Core advantages and technical highlights

High-density I/O capacity: With 16 inputs and 16 outputs in a single rack slot, the 3500/62 maximizes space efficiency while handling diverse control tasks. This density allows it to manage multiple functions—such as monitoring valve positions (inputs) and activating cooling systems (outputs)—without requiring additional modules, simplifying system architecture and reducing costs.

Flexible input/output options: The module accepts both dry contact and voltage inputs, making it compatible with a wide range of sensors and switches. Its Form C relay outputs (SPDT) offer versatility in control circuits, supporting both normally open and normally closed configurations. This flexibility ensures the 3500/62 integrates seamlessly with legacy equipment and modern systems alike.

Rapid response times: With a 2ms input response time, the 3500/62 quickly processes status changes—critical for time-sensitive applications like turbine overspeed protection. When paired with the 3500/33-01-00 vibration module, it ensures that dangerous conditions trigger immediate outputs, such as shutting down machinery before damage occurs.

Seamless system integration: Powered by the 3500/15 106M1079-01, the 3500/62 communicates with other 3500 series modules via the backplane, enabling coordinated responses to system alarms. For example, it can activate a visual alarm when the 3500/42M 140734-02 detects high bearing temperatures, while simultaneously sending a shutdown signal to a motor controller. Configuration via 170180-01-00 software allows users to program custom logic tailored to specific processes.

Typical application scenarios

In a natural gas processing plant, the 3500/62 acts as the control hub for a compressor station. Its inputs monitor pressure switch statuses and valve positions, while outputs control emergency shutdown valves and alarm sirens. When the 3500/33-01-00 detects excessive vibration, the 3500/62 immediately closes the fuel supply valve (via an output) and sounds the alarm, preventing a potential explosion. The module’s integration with the 3500/15 106M1079-01 ensures uninterrupted power during this critical response.

At a coal-fired power plant, the 3500/62 manages the auxiliary systems of a steam turbine. Its inputs track pump running statuses and filter differential pressures, while outputs control lube oil pumps and heater elements. When the 3500/42M 140734-02 signals low oil pressure, the 3500/62 activates a backup pump and sends an alert to the 3500/50 288062-02 operator interface, ensuring operators address the issue before turbine damage occurs.

In a paper mill’s pulp processing line, the 3500/62 monitors and controls a digester system. Inputs detect door closure status and pressure relief valve actuation, while outputs control steam valves and agitator motors. Configured via 170180-01-00 software, it interlocks with the 3500/33-01-00 to prevent the agitator from starting unless the digester door is fully closed—enhancing operator safety and process integrity.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the 3500/62, ensure the 3500 series rack is powered off (via the 3500/15 106M1079-01 power supply). Mount the module in a single rack slot, securing it with screws torqued to 0.6 Nm. Use shielded twisted-pair cable for input/output wiring, with wire gauge appropriate for the load (16-22 AWG). Separate input wiring from high-voltage output cables to prevent interference. Label all connections clearly to simplify troubleshooting.

Maintenance suggestions: Inspect the 3500/62 monthly for loose terminal connections or corrosion, especially in humid environments. Clean terminals with a dry cloth if needed. Test relay outputs quarterly by activating them via 170180-01-00 software and verifying contact operation with a multimeter. Check input response times annually using a signal generator to ensure they remain within the 2ms specification. If relays fail to operate, replace the module during a scheduled shutdown—hot-swapping is not recommended for safety-critical outputs. Store spare 3500/62 units in a dust-free environment to ensure reliability.
