3500/62 133811-03 Process Variable Monitor Bently Nevada

Hardware Specifications

Process Variable Signal Processing

The 3500/62 family accepts proportional electrical signals representing machine-related process conditions. The selected I/O type determines the physical input interface. Current-input configurations use 4-20 mA signals, while voltage-input configurations support proportional signals within the documented -10 to +10 VDC range.

The module conditions the input signal and evaluates the resulting value against programmed under and over setpoints. The Alert and Danger delay parameters provide time qualification for the corresponding alarm states. Engineering-unit mapping can represent up to 20,000 units across the configured input span.

The supplied information confirms the 3500/62 family functions but does not establish that every family-level specification applies specifically to the listed 133811-03 assembly.

Frequently Asked Questions

Q: Does 133811-03 establish a specific I/O configuration?

A: No. The supplied documentation identifies 133811-03 as the spare model for this listing but does not establish a specific voltage, isolated-current, or internal-barrier current I/O configuration.

Q: How many process-variable channels does the 3500/62 family monitor?

A: The documented family specification provides six monitored channels. This should be treated as a family-level specification rather than a separately verified board-level characteristic of 133811-03.

Q: What alarm timing parameters are documented for the 3500/62 family?

A: The family documentation specifies an Alert delay of 1-60 seconds in 1-second steps and a Danger delay of 1-60 seconds in 0.5-second steps.

Field Installation Guidelines

Confirm the installed 3500/62 I/O configuration before connecting field wiring. Voltage and current inputs require the corresponding matching I/O arrangement.

Route analog signal wiring separately from high-current power conductors and switching circuits where practical. Maintain appropriate cable shielding and grounding practices for the installed system design. Do not connect a field signal to an incompatible I/O type.

Verify signal polarity, terminal identification, and loop continuity before applying the field signal. For 4-20 mA configurations, confirm the complete current-loop path. For voltage configurations, verify the signal reference and ensure that the applied signal remains within the documented input range.

Use the installed system documentation to verify termination requirements, rack position, channel assignment, and configured alarm limits. Do not infer these details from the 133811-03 identifier alone.
