Counter Timer RS422/RS485 IO AP484

The AP484 Series is an AcroPack® Module that is a six 32-bit Counter Timer Module for RS422/RS485 Communication Events. It provides support for internal or external triggering and simplifies the synchronisation of operations to specific events. It contains a wide temperature range in a PCIe bus interface format.

Designed for COTS applications where general purpose I/O modules deliver high speed and resolution for RS422/485 communications.

The Acromag AP484 Series is a Counter Timer RS422/RS485 IO module that delivers high speed and resolution for Communications.

Firstly, the AP484 Series is based on the Acromag AcroPack® product line, which has a PCIe interface format. AcroPack® offers products in a compact size, at a low cost with the same functionality and memory map of existing Industry Pack Modules in a rugged form factor. Also they are RoHS compliant. This module contains a 62.5MHz clock time base to provide accurate time synchronisation. The Single counter / timer modes include: event counting, frequency measurement, period/pulse width measurement, quadrature position measurement, pulse width generator and several more which is handled by a single register to simplify programming. It has a RS422/RS485 driver interface.

Secondly, the AP484 modules are 70mm long and only 19.05mm longer than a full length mini PCIe card. It contains a down facing connector which internally routes I/O signals through the carrier card to secure field connectors. Therefore, eliminating loose cables and increasing reliability.
