More on the SBS90M Signal Conversion Module: Applications in Focus

In a nutshell: Shanghai Sibo’s SBS90M Signal Conversion Module integrates acquisition (6-channel analog + 10-channel switch inputs) and Bus communication (RS232, RS485, RS422, Modbus, USB FS HID, CAN2.0A/B, CANopen) into one robust industrial-grade device.
Expertly engineered for “acquisition” and “reading,” it efficiently handles multi-signal inputs from analog sensors (analog + switch signals) and multi-axis analog inputs (0–5V) + button (TTL) inputs from joystick products. The module then flexibly converts these into single or multiple Bus interface signals, supporting a variety of protocols to meet diverse industrial output requirements.

02 Application scenarios
Application 1: DCS Analog Signal Acquisition (Digital remote transmission of analog signals)
Features: Enables distributed signal acquisition and bus-based digital transmission for DCS
Which solves problems including excessive wiring for long-distance analog signals, complex wiring, signal attenuation, susceptibility to interference, high installation and maintenance costs, and low reliability.

Application 2: Multi-Axis Joystick Position & Button Signal Acquisition
Features: Collects multi-axis analog signals and multi-switch inputs from remote control boxes/units, with bus-based remote transmission
Which is directly compatible with multi-axis joysticks (up to 6 axes) or control boxes, armrest consoles, and remote control boxes, with centralized acquisition followed by bus-based data upload.

Application 3: Multi-Output Signal Applications
Features: Remote data management, local acquisition/control, and local data monitoring
Which solves multi-location data sharing and local monitoring needs
Example configuration:
1、RS485 Modbus (remote) + RS232 (local)
2、RS485 Modbus (remote) + CANopen (local control) + HMI monitoring

Application 4: Dual-Network Data Sharing
Features: Enables direct data sharing across dual networks (e.g., CANopen + Modbus) without additional converters
Which solves the need for seamless data sharing between CAN and 485 networks
