System compatibility

XVME-201 belongs to XYCOM XVME series DIO module.

It installs in XYCOM VME chassis and cooperates with XVME series CPU and I/O modules.

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

Digital signal acquisition and output expansion for VME control rack.

48 channels TTL bidirectional digital I/O,collect field switch and digital sensor signals.

Output switch control signals to relays,solenoids and other field actuators.

Built-in dual 24-bit programmable timers,generate timing pulse and delay signal.

Support VME interrupt function,real-time response to field signal changes.

Real-time digital data interaction with main CPU through VME backplane bus.

Onboard self-test for I/O circuit,timer unit,data bus and VME bus interface fault inspection.

Installation

Power off VME chassis.

Insert XVME-201 card into empty VME slot,tighten front panel fixing screw.

Connect field digital signal wiring to 50pin front panel ribbon connector.

Power on chassis,run hardware self-test.

VME CPU scans bus,identifies the board and starts digital I/O operation.

Interface

VME P1 backplane connector,50pin ribbon cable terminal,LED indicators:PASS,FAULT.

Feature

Single height VME TTL DIO board,XYCOM XVME series digital I/O module.

48-channel bidirectional TTL digital input and output,6 independent 8-bit ports.

Dual 24-bit programmable timers,support timing and pulse generation.

Built-in signal filtering and EMC protection,suppress field electromagnetic interference.

Industrial grade circuit design,stable operation under vibration environment.

VME slave interface,easy plug-in installation.

Discontinued obsolete VME module,supply only for old production system spare replacement.

Vibration resistant PCB design,suitable for turbine control cabinet.

Diagnostic

FAULT LED on:I/O circuit damage or VME bus communication failure;

Cannot be identified by CPU:check VME backplane contact and address jumper setting;

Channel abnormal:check field wiring and TTL signal loop status;

Timer or interrupt failure:check interrupt level jumper configuration.
