Product Details Introduction

Xycom XVME-491 Communication Module

XVME-491 is a 6U dual high single width VME bus four channel RS-422A/RS-485 serial communication module launched by Xycom, designed for industrial long-distance, multi node, and high anti-interference communication scenarios. I/O signals are output through the VME P2 backplane.

Adopting a 6U dual height single width VME architecture, occupying P1+P2 backplane slots, compatible with standard VME chassis.

Provide 4 independent RS-422A/RS-485 differential serial interfaces, supporting full duplex/half duplex transmission.

Built in 2 Zilog Z8530 serial communication controllers (SCC), compatible with multiple communication protocols.

Each channel has an independent programmable baud rate generator, with a maximum asynchronous speed of 57.6 KB/s and a maximum synchronous speed of 500 KB/s.

Support RS-485 multi node networking and adapt to industrial bus cascading and distributed device communication.

Differential signal transmission, strong electromagnetic interference resistance, supports long-distance communication up to 1200 meters.

Each channel supports modem control signals such as RTS/CTS/DCD, and is compatible with industrial equipment handshake.

Supports multiple communication modes such as asynchronous, byte synchronous, and bit oriented, suitable for various industrial control scenarios.

Occupy 1KB of aligned VME short I/O address space, with optional base addresses for jumpers, making system addressing convenient.

7 levels of VME interrupt levels are optional, supporting 16 independent interrupt vectors for efficient response.

Industrial grade wide temperature design, operating temperature range of 0 ° C to 65 ° C, non operating range of -40 ° C to 85 ° C.

Power requirements:+ 5V@1.4A (Typical)/1.6A (maximum)+ 12V@100mA (Typical).

Compliant with VMEbus A16: D08 (O) device specifications and compatible with mainstream VME control systems.

The I/O signal is output through the VME P2 backplane without a front panel interface, making it suitable for internal integration in the cabinet.

Widely used in industrial automation, rail transit, power monitoring, remote data collection and other scenarios.

XVME-491, with its characteristics of differential isolation, long-distance transmission, and backplane integration, has become the core module of RS-485/422 industrial communication in VME systems, adapting to the multi device networking requirements in complex electromagnetic environments.
