Function

Integrated digital input,digital output and analog signal processing channel.

Collect field switch quantity and analog signals such as pressure,temperature,vibration.

Output control signal to drive on-site actuators,solenoid valves and relays.

Transmit sampling data and receive control instructions via VME backplane with main CPU.

Onboard self-test for I/O channels,signal circuit and VME bus interface fault inspection.

Installation

Power off VME chassis.

Insert 81987-101B1805 card into empty VME slot,tighten front panel fixing screw.

Connect field sensor and actuator wiring to front terminal connector.

Power on chassis,run hardware self-test.

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

Interface

VME P1 backplane connector,front multi-signal terminal connector,LED indicators:PASS,FAULT.

Feature

Single height VME universal mixed I/O board,XYCOM 1805 series,101B enhanced channel configuration variant.

Combined analog and digital channel design,reduce rack slot occupation.
