Main Functions

Provides 48‑channel bi‑directional TTL‑level digital input and output via PCI bus, compatible with i8255 Mode 0 operation. Channels can be configured as input or output in 8‑bit or 4‑bit groups by softwareCONTEC.
High‑speed signal response, maximum 200 ns input / output response time for TTL digital signals; supports positive‑logic 5VDC‑TTL signal transmissionCONTEC.
All 48 channels can be set as interrupt‑trigger input channels to capture external hardware trigger events for host‑side program responseCONTEC.
Equipped with built‑in bus transceivers to enhance driving capacity for digital I/O lines. Features dual 50‑pin external connectors compatible with OPTO‑22 peripheral modules for field wiring expansionCONTEC.More products: www.plcva.com
Communicates with industrial host PC over standard PCI bus. Transmits digital input status to CPU and executes digital output commands issued by application software. Official API‑PAC driver libraries support Windows and Linux operating systemsCONTEC.
Non‑isolated TTL circuit design; reads status from external switches, proximity sensors and outputs digital control signals to TTL‑compatible actuators, relays and logic circuits.

CONTEC PIO‑48D(PCI) 7145A Digital I/O PCI Industrial Control Board

Plug‑in PCI peripheral board installed inside industrial PC / industrial control workstation, used for general‑purpose digital signal acquisition and logic control in industrial automation systems.
Widely deployed for equipment interlock signal reading, sensor status acquisition, trigger signal detection, and logic‑level output control for actuators. Typical scenarios include production‑line automation, test‑bench control, semiconductor equipment auxiliary I/O, and custom industrial inspection systems.
Reads digital status from limit switches, photo‑electric sensors, proximity switches; outputs TTL control signals to drive relay modules, indicator lamps and logic‑level‑controlled peripherals. Supports hardware interrupt‑based event capture for real‑time logic response.
Model 7145A (PIO‑48D(PCI)) is an end‑of‑life original Contec hardware unit, commonly used as spare replacement part for legacy industrial equipment maintenance, restoring 48‑channel digital I/O capability for aging production machines and test systems.
