The 1900-65A-167699-02 is the dedicated, optional Separate Display Module/Keypad for the 1900/65A General Purpose Equipment Monitor system. This module operates as the localized hardware interface, enabling the viewing of realtime channel values, system statuses, and the execution of minor configuration changes without an external PC. The mechanical and electrical framework supports remote installation, allowing this specific display hardware to be mounted at a localized physical control panel up to 75 metres (250 feet) away from the main Monitor Module via a dedicated serial interconnecting cable.

When paired with the main monitor module, the complete 1900/65A package executes continuous monitoring and protection for rotating assets. The underlying hardware architecture provides four transducer inputs and four temperature inputs. Each transducer channel can be configured via software to support 2-wire or 3-wire accelerometers, velocity sensors, or proximity probes. Each temperature channel interfaces directly with Type E, J, K, and T thermocouples, alongside 2-wire or 3-wire RTD configurations.
The integrated infrastructure delivers six relay outputs, four 4-20 mA recorder loops, and a dedicated buffered analog output port for raw transducer signals. Relay contacts execute trip logic based on the programmed OK, Alert, and Danger states of the input channels. Network integration is handled through Modbus communications via Ethernet or a software-configurable RS232/485 serial port, routing static variables, event lists, and time-stamped status logs to Distributed Control Systems (DCSs), SCADA systems, or Programmable Logic Controllers (PLCs). Configuration mappings are stored permanently in the non-volatile memory of the base module.

Oil & Gas Extraction
Mounted on the control cabinet panels of crude oil transfer pumps on offshore drilling platforms to enable direct on-site viewing of 4-channel vibration amplitudes and 4 temperature values.
Petroleum Refining
Functions as the local box operator interface for heavy oil pumps in hydrogenation units, executing alarm resets via the 6-button physical keypad without an external PC.
Thermal Power Generation
Deployed on small weatherproof enclosure panels near boiler forced-draft fans, establishing serial data interconnection with the main monitor module located 75 meters away via a dedicated cable.
Hydroelectric Power Plants
Embedded into the front covers of auxiliary low-voltage distribution cabinets for hydro-turbines to read the static bias gap voltages of rolling element bearings via the built-in LCD screen.
Nuclear Power Plants
Installed on the local control panels of auxiliary circulating water pumps in conventional islands to provide a physical display layer for OK, Alert, and Danger hardware indicators.
Iron & Steel Smelting
Deployed on the panels of soundproof control rooms in blast furnace dedusting fan houses, utilizing the backlit LCD to read real-time casing acceleration metrics in dusty environments.
When operating the Bently Nevada 1900-65A-167699-02 separate display module, mechanical installation must ensure the total routing length of the dedicated communication cable to the main monitor module does not exceed 75 metres (250 feet) to prevent serial signal attenuation and the cabinet interior must remain dry and dust-free to comply with the rear IP20 rating.
Meanwhile any physical removal, cable plugging/unplugging, or maintenance must be conducted with the system power completely disconnected and technicians must wear an anti-static wrist strap throughout the process to fully eliminate physical damage to internal integrated circuit chips caused by live hot-swapping or electrostatic discharge.
1900-65A-167699-02 features an independent buffered output physical diagnostic jack on the panel surface for external testing instrument attachment, alongside status indicators for Not OK, Alert, and Danger states. This display unit mounts directly onto the front cover of the monitor main module or installs as a separate remote panel via a dedicated electrical cable, supporting a maximum wiring distance of up to 75 meters within an industrial operating temperature range from -20°C to +70°C. The module operates independently from the underlying emergency shutdown relay interlock logic, ensuring that its removal or single-point failure will not interrupt the digital monitoring loops of the main module.
It is the dedicated local display and keypad module for the Bently Nevada 1900/65A General Purpose Equipment Monitor system.
What physical interactive interfaces does the 1900-65A-167699-02 main hardware contain?
The front of this hardware integrates a liquid crystal display (LCD) and a set of physical mechanical keys used for parameter switching and minor configuration adjustments.
How to physically install and secure the 1900-65A-167699-02 module?
It can be secured directly onto the front cover of the 1900/65A monitor main module via fastening screws, or remote panel-mounted separately using a dedicated cable.
What field variables can the 1900-65A-167699-02 display without an external computer?
It directly displays the vibration amplitudes and gap voltages from the 4 vibration channels, alongside real-time physical measurement values from the 4 temperature channels.
Where is the operating power for the 1900-65A-167699-02 derived from?
It extracts low-voltage DC operating voltage directly from the internal power loops of the 1900/65A monitor main module via the connected dedicated communication cable.
