This board interfaces industry-standard Industrial I/O Pack (IP) modules to a PCI bus on a PC-based computer system. The half-length card is ideal for use in smaller PC chassis.

Three IP module slots give you the freedom to mix a variety of I/O functions (A/D, D/A, digital in, digital out, serial I/O, etc.) on a single board. Or, combine modules of the same type for dozens of channels on a single card. Either way, the APC8621A saves your precious card slots and reduces your costs.

Select I/O modules from Acromag’s offering of more than forty models or use any third-party IP mezzanine ANSI/VITA 4 modules.

The APC8621A is a drop-in replacement for the APC8621, please see the known differences document below for more information.

Specifications

IP Module Compliance (ANSI/VITA 4)

Meets or exceeds all written IP specifications per ANSI/VITA 4-1995 for 8MHz or 32MHz operation. Supports Type I and Type II ID space formats.
Electrical/mechanical interface: Supports three single-size IP modules (A-C), or one double and one single-size IP module. 32-bit IP modules are not supported.
IP module I/O space, ID space, INT, and MEM space supported.
IP module I/O space: 16 and 8-bit; supports 128 byte values per IP module.
IP module ID space: 16 and 8-bit; Supports Type I 32 bytes per IP (consecutive even byte addresses) and Type II 32 words per IP via D16 data transfers.
IP module memory space: 16 and 8-bit; supports up to 8M bytes of memory space per IP module.
Interrupts: Supports two interrupt requests per IP and interrupt acknowledge cycles via access to IP INT space.

PCI Bus Compliance

This device meets or exceeds all written PCI local bus specifications per rev. 2.2 dated December 1998.
System base address: This board operates in PCI memory space. It requires 1K of memory space for mapping the carrier controls, and IP module ID, INT, and I/O space. An optional 64MB of PCI memory space is required to use IP module memory space.
Data transfer bus: Slave with 32, 16, and 8-bit data transfer operation. 32-bit read or write accesses implemented as two 16-bit transfers to IP modules.
Interrupts (PCI bus INTA# interrupt signal): Up to two requests sourced from each IP mapped to INTA#. Interrupt vectors come from IP modules via access to IP module INT space.

Environmental

Operating temperature: 0 to 70°C (APC8621) or -40 to 85°C (APC8621E model).
Storage temperature: -55 to 100°C (all models).
Relative humidity: 5-95% non-condensing
Power: 3.3 Volts (±10%): 130mA, typical; 50mA max. 5 Volts (±5%): 30mA, typical; 50mA, max. ±12 Volts provided to each IP module.

  • Description

    Screw terminal panels simplify field signal wiring. A cable connector provides a clean interface to the I/O board or module.

    Many termination panels have a compact footprint and mount neatly on a DIN rail strip. Other panels are designed for mounting directly onto a standard 19-inch computer rack.

    All of Acromag’s I/O boards have a corresponding termination panel. This convenience saves you the time and hassle of finding a compatible panel or crafting your own.
