Counter Timer TTL and RS422 IO AP483

The AP483 Series is an AcroPack® Module that is an eight 32-bit Counter Timer Module for TTL and RS422 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 TTL communications

The Acromag AP483 Series is a Counter Timer TTL and RS422 IO module that delivers high speed and resolution for TTL Communications.

Firstly, the AP483 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. Available with TTL and RS422/RS485 driver interface.

The AP483 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.

Features of the Counter Timer TTL and RS422 IO Module AP483 includes:

  • PCI Express Generation 1 interface
  • Eight 32-bit counter/timers
  • Mix and match countless I/O combinations in a single slot.
  • Available with TTL and RS422/RS485 Driver Interface
