BENTLY 3500/20 125760-01 Rack Interface Module

BENTLY 3500/20 125760-01 (Data Manager I/O Module, RIM Subcard)
125760-01 is the data manager I/O rear card * * of the 3500/20 Rack Interface Module (RIM), paired with the front card (such as 125744-02), responsible for Ethernet+high-speed data management; 2026-05 has been discontinued and replaced by 3500/22M as a whole.

1、 Basic Information
Model: 3500/20 125760-01
Brand: Bently Nevada, Baker Hughes）
Series: 3500 Mechanical Protection System (TSI)
Type: RIM Data Manager I/O Rear Card (Non independent RIM, must be equipped with front card)
Status: Discontinued (DISC), market dominated by second-hand/refurbished
Installation: Insert it into the back of the 3500/20 front card (125744-02), occupying slot 1
Positioning: RIM’s high-speed communication and data management expansion card
2、 Relationship with Standard RIM (125744-02)
125744-02 (front card): Standard RIM, providing RS232/RS422+basic configuration+OK relay.
125760-01 (rear card): Data Manager I/O card, adding Ethernet (TCP/IP), high-speed data acquisition, and large capacity storage to RIM.
Pairing rule: 3500/20 machine=125744-02 (front)+125760-01 (back), used for scenarios that require Ethernet communication and transient data caching.
3、 Core functions
Ethernet communication: 10/100Mbps TCP/IP, directly interfaces with System 1 or DCS, without the need for TDXnet.
High speed data management: With a maximum sampling rate of 24kHz, it can store over 1 million measurement points and cache transient waveforms.
Multi protocol support: compatible with Bently proprietary protocols Modbus TCP/IP， Compatible with DCS/PLC/SCADA.
System Expansion: Supports hot plugging and can work in conjunction with TDXnet/TDIX/DDIX.

4、 Technical parameters
Power supply: 12-32V DC, power consumption * *<10W**
interface
Ethernet: RJ45, 10/100Mbps
Serial port: RS232/RS422 (via front card)
Dimensions (H × W × D): 229 × 102 × 44mm
Weight: Approximately 1.5kg
Working temperature: -40 ℃ to+85 ℃
Storage capacity: up to 1 million measurement data points

125768-01 RIM I/O Rear Card RS232/RS422 Serial Port Expansion, No Ethernet
125760-01 Data Manager I/O Rear Card Ethernet+Serial Port High speed Data and Ethernet Communication
6、 Procurement and substitution
Price: Second hand/refurbished approximately * * $1200- $2000 * *; The inventory of new goods is approximately * * $3000- $4500 * *.
Alternative solution: The new project directly uses 3500/22M (288055-01), integrating RIM+TDI, with built-in Ethernet+USB, completely replacing the 3500/20+125760-01 combination.
