Frequently Asked Questions (FAQ)

What type of inputs does the 3500/72M 140482-01 I/O Module support?
It accepts 1 to 4 proximity probe signals, typically used to monitor rod position in reciprocating compressors.

What is the primary application of the 3500/72M Recip Rod Position Monitor?
The module is designed for monitoring rod position, rod drop, and hyper-compressor displacement in reciprocating compressors in compliance with API 618.

What are the key output features of this I/O module?
Each channel has a front-panel buffered transducer output with short-circuit protection and a 510 Ω output impedance.

What signal conditioning capabilities are included?
The module includes fixed and notch filtering for peak-to-peak amplitude, gap, and average piston position. It also features notch filters for 1X and Not 1X amplitudes.

What accuracy can be expected from measurements such as rod position and gap?
Typical accuracy is within ±0.33% of full-scale, with a maximum deviation of ±1%. Rod position angle and crank angle are typically accurate within ±1°.

How is alarm management handled?
Alarm thresholds (alert and danger) are configurable via 3500 Rack Configuration Software. Alarm setpoints are adjustable from 0–100% of full-scale values.

What temperature conditions is the module designed to operate under?
It operates reliably from -30°C to +65°C with standard I/O, and from 0°C to +65°C when using internal barrier I/O modules.

What are the physical installation requirements?
The I/O module occupies one full-height rear slot in a 3500 rack. It measures 241.3 x 24.4 x 99.1 mm and weighs 0.20 kg.
