Description
The BENTLY 3500/32M 4-Channel Relay Module is a full-height component for the Bently Nevada 3500 monitoring system, providing four independent relay outputs to trigger alarms, shutdowns, or external controls based on machinery health conditions. It ensures reliable signal actuation in vibration and protection applications for rotating equipment.
Product Parameters
This module consumes 5.8 W typical power from rack supply, with four single-pole double-throw (SPDT) relays rated for 5 A max switched current at 30 VDC/250 VAC resistive loads. It features switch-selectable normally energized/de-energized operation, epoxy-sealed relays with arc suppression, and environmental specs of -30°C to +65°C operating temperature plus 95% humidity tolerance.
Datasheet Overview
The datasheet specifies OK/TX-RX/Channel Alarm LEDs for diagnostics, dimensions of 241 x 24.4 x 242 mm (main) and 241 x 24.4 x 99.1 mm (I/O), total weight around 1.1 kg, and compatibility requiring 3500/22 TDI module with firmware Rev. X or later. It supports hazardous area approvals (cNRTLus Class I Div 2, ATEX Zone 2) and full-height rack slot usage.
