Technical Specifications and Hardware Overview
The Bently Nevada 130730-01 operates as a signal input and relay card for the 3500 series monitoring system. This card measures 152 mm in height, 30 mm in width, and 110 mm in depth for compact panel mounting. It weighs approximately 0.55 kilograms, which enables straightforward handling during installation. The unit draws 0.25 A from a 24 V DC supply, consuming roughly 6 W under normal operation. It provides 8 digital input channels for monitoring external field contacts. The card also includes 8 relay outputs with Form C contact configurations.
Each relay supports switching voltages up to 220 V AC or 30 V DC. The contacts handle continuous currents up to 1.5 A with a 45 W switching capacity. The inputs accept dry contact closures or 24 V DC signals from sensors. The unit offers a relay response time of 6 ms for alarm activation. It features optical isolation between the input signals and output relays. The card includes LED indicators for power and each channel status. The operating temperature range spans -20°C to 65°C for harsh environments. Storage temperatures extend from -40°C to 85°C without causing damage. Humidity tolerance covers 5% to 95% non-condensing conditions.

Signal Input and Relay Functionality
This card acquires 8 digital signals from field switches and proximity sensors. It routes these signals to corresponding relay outputs for alarm distribution. The Bently Nevada 130730-01 provides 8 independent Form C relays for versatile control. Each relay channel maps directly to a specific input for straightforward pairing. The unit uses optocouplers to isolate field wiring from internal logic circuitry. It includes manual override switches for testing each relay channel independently. The card supports both normally open and normally closed contact wiring options.
Installation and Reliability Information
The 130730-01 mounts onto a DIN rail or panel surface within cabinets. It requires 20 mm clearance above and below for adequate airflow. The card connects to field devices via a removable terminal block. It interfaces with PLC systems through relay contact outputs. The unit delivers a mean time between failures of 180,000 hours. It carries CE, ATEX, and CSA certifications for global deployment. The module passes vibration testing at 10 to 55 Hz with 0.15 mm amplitude. It withstands shock loads up to 5 g for 30 ms duration.
