BENTLY NEVADA 136294-01 Isolated 4-20 mA I/O Module

Description

The BENTLY NEVADA 136294-01 Isolated 4-20 mA I/O Module is a PV-isolated ground I/O module designed for industrial signal management, part of the Bently Nevada 3500/25 series. Core functions include signal acquisition, conversion, output, and both analog and digital signal processing, with compatibility for proximity probe or magnetic pickup input signals that it converts to digital keyphasor signals. It supports remote communication via LAN, serial, and digital I/O interfaces, enabling seamless integration with control systems. Key technical specifications include a 24VDC input voltage, output signals of 4-20 mA or MODBUS, an operating frequency range of 0.5 to 10,000 Hz, and an operating temperature range of -40 degrees Celsius to +85 degrees Celsius. Measuring 2.5 cm x 12.7 cm x 25.4 cm and weighing approximately 0.4 kg, the module features high-performance isolated I/O functionality to ensure system stability and safety. It also provides 4 independently programmable relay outputs, and supports firmware field upgrades and asset management data reporting. Ideal for applications requiring signal isolation, such as multi-device keyphasor signal connection and integration with control systems, it is compatible with Proximitor applications when external power is provided, primarily for shaft speed measurement with optional phase measurement capability.
