System compatibility

70240-001 XVME-240 belongs to XYCOM XVME series VME I/O board.

It plugs into VME chassis and cooperates with XVME series CPU board.

Compatible with turbine,compressor and legacy DCS control systems via VME bus.

Commonly used for power plant,oil & gas,petrochemical old equipment maintenance and spare replacement.

Function

Collect field discrete TTL digital signals,switch status and equipment feedback signals.

8 byte-wide bidirectional ports,each port can be independently configured as input or output via register setting.

8 hardware interrupt input lines,support rising/falling edge latch,programmable interrupt mask.

8 flag output lines,used for external interrupt acknowledge or auxiliary control signal output.

Communicate with VME host CPU for digital data read and write.

Onboard self-test circuit for channel and hardware fault inspection.

Installation

Power off VME chassis.

Insert 70240-001 XVME-240 card into empty 6U VME slot,tighten front panel fixing screw.

Connect field digital wiring to module 100-pin front connector.

Power on chassis,run VME system scan and self-test program.

Configure port direction register,test each input and output channel signal status.

Interface

VME P1/P2 backplane connector,100-pin front signal connector,LED indicators:PASS,FAIL.

Feature

Single height 6U VME standard board,easy installation in VME rack.

High density 80-channel DIO design,suitable for large quantity discrete signal collection.

Programmable port direction,edge-selectable interrupt function for fast event response.

Discontinued obsolete VME digital I/O module,supply only for old production system spare replacement.

Vibration resistant PCB design,suitable for continuous long-time industrial operation.

Diagnostic

FAIL LED on:channel overvoltage or backplane poor contact;

Individual channel no reading:check field wiring and port configuration register;

Interrupt no trigger:check interrupt mask register and jumper edge setting.

Product Brief
