3500/20 Physical parameters:
Power consumption: The typical value is 4.75 watts.
Maximum current:<1mAdc (from dry contact to common terminal).
Dimensions: 9.5 inches high, 0.96 inches wide, and 9.52 inches deep.
Weight: Approximately 0.91 kilograms.
3500/20 Installation Dimensions:
Bottom plate installation: 51mm x 51mm, installed with four M4 x 12 GB29-76 bolts;
Rail installation: It can be easily installed on a standard 35mm rail.
Option description:
Rack interface type: There are two options: standard RIM (for standard monitoring) and TMR RIM (only applicable to applications requiring three module redundant configuration).
3500/20 Compatibility:
Supports compatible Bently Nevada external communication processors such as TDXnet, TDIX, etc.
Cable length:
The maximum length is 30 meters (100 feet).
High current:
<1 mA DC, dry contact to common terminal.
3500/20 Function:
RIM not only serves as a basic interface, but also supports data collection and transmission functions. When used in conjunction with M-series monitors (such as 3500/40M, 3500/42M, etc.), it can continuously collect steady-state and transient waveform data, and transmit the data to the main computer software through Ethernet.
3500/20 Features:
Online monitoring and protection: providing continuous online status monitoring and protection for your unit equipment 1
Self detection and fault-tolerant design: can be configured with multiple redundancies, ranging from adding a second fully redundant power supply to a complete triple modular redundancy (TMR) configuration 1
Monitor channel comparison function: For Triple Modular Redundancy (TMR) applications, the 3500 system requires TDI in the form of TMR. In addition to all the standard TDI functions, TMRTDI also has a “monitor channel comparison function”. By selecting the installation function of the monitor option, the 3500TMR configuration executes the monitoring voting function. In this way, TMRTDI continuously compares the outputs of three redundant monitors. If TMRTDI detects that the output information of one monitor is not equal to the other two monitors (within the configured percentage), it will issue an error indication to the monitor and add an event 6 to the system event list
Location and compatibility:
The framework interface module must be placed in the first slot in the framework (next to the power supply).
RIM can be connected to compatible Bentley communication processors such as TDXnet, TDIX, and DDIX.
3500/20 Function and Features:
RIM provides certain common functionalities for each framework, such as data collection and framework configuration.
The front panel and rear I/O modules of RIM have RS-232/RS-422 serial interfaces, which can be connected to the host for data acquisition and framework configuration.
The maximum baud rate of the RS-232 interface is 38.4K, and the cable length is required to be a maximum of 30m; The maximum baud rate of the RS-422 interface is also 38.4K, but the cable length can reach up to 1200m.
The RS-422 interface also supports communication between multiple 3500 frames and 3500 host software via chain connection.
3500/20 Importance and Impact:
Although RIM provides some common features for the entire framework, it is not a part of the critical monitoring path.
The operational status of RIM has no impact on the correct and normal operation of the entire monitoring system.
Three module redundancy (TMR) application:
For applications that require three module redundancy (TMR), the 3500 system requires a TMR version of the RIM.
In addition to all standard RIM functions, TMR RIM also performs “monitor channel comparison” to enhance system reliability and safety.
3500/20 Other features:
RIM has high reliability and can operate stably in harsh working environments, ensuring the reliability and stability of the system.
RIM has fast signal processing capability and response speed, which can achieve real-time control and monitoring, improve the performance and response speed of the entire system.
RIM has self diagnostic and fault alarm functions, which facilitate user troubleshooting and maintenance, reducing maintenance costs and time costs.
