Functional Features
Dual independent serial ports. Supports multiple standard industrial protocols. Configurable baud rate, parity and data bits. Status indicators per port. Hot-swap capability. Spring-cage terminal connections.
Application Scenarios
It connects serial devices such as bar code readers, weigh scales, process instruments, drives and third-party controllers to X20 automation systems.
Performance Parameters
Baud rate: up to 115200bps. Data bits: 7, 8. Parity: none, even, odd. Operating temperature range: -25°C to +60°C. Vibration resistance: 2G @ 10Hz to 500Hz.
Material Composition
Housing: flame-retardant plastic. PCB: FR-4. Transceivers: industrial serial drivers. Terminals: spring-cage copper alloy.
Structural Characteristics
It features X20 standard module form factor, front panel port status LEDs, spring-cage terminal block, side bus connector, and DIN rail mounting base.
Working Principle
It receives serial data from field devices, converts it to X20 bus format, and passes it to the CPU. It also converts CPU data into serial protocol signals for transmission to connected serial devices.
Installation Requirements
Mount on X20 DIN rail base. Wire serial devices to terminal block. Configure protocol parameters via Automation Studio. Set baud rate and parity to match connected device.
