Import 3500/33 16-Channel Relay Module — Buy in wholesale FOB from Supplier in China

The Bently Nevada 3500/33 16-Channel Relay Module serves as an alarm output and control interface within the 3500 series machinery protection system. This full-height rack module accepts digital alarm inputs from 3500 monitor modules and converts them into relay contact closures for machine trip circuits, indicator lamps, and plant distributed control systems. N.S.E.Automation Co.,Ltd. sources this component as an OEM spare for industrial users in power generation, oil and gas, petrochemical, and heavy manufacturing sectors. The module's 16 independent relay channels provide extensive flexibility for alarm grouping and voting logic configurations.

Construction employs industrial-grade PCB composite substrates with nickel-plated relay contacts housed in a steel enclosure designed for continuous operation in industrial control room environments. Each relay channel typically offers programmable normally open or normally closed contact configurations, with contact ratings standard for 3500 series relay modules at 120 VAC or 24 VDC at specified current loads. The module integrates with the 3500 rack backplane for power and communication, eliminating external wiring to individual monitors. Channel-to-channel isolation and contact protection circuits protect against inductive load damage and electrical noise common in rotating equipment installations.

Buyers for this 3500/33 module include plant maintenance engineers holding spare parts inventory, system integrators expanding existing 3500 installations, and reliability contractors performing upgrade projects. The module's compatibility extends across 3500 series monitors including vibration, thrust position, and temperature channels. N.S.E.Automation Co.,Ltd. does not specify exact stock quantity, individual unit serial numbers, or factory certification status in its listing. Prospective purchasers should confirm whether the unit is new surplus, factory-sealed, or refurbished, and verify relay contact electrical ratings against their specific load requirements before ordering.

N.S.E.Automation Co.,Ltd. operates from Unit B14 in Binglangxili, Siming District, Xiamen, Fujian Province, China, postal code 361000. The company holds a Harbor trust tier on the platform with a recorded response rate of 0.00 percent and zero average response hours.
