B&R 3IF797.9-1 aPCI Interface Module Introduction & Technical Specifications

Basic Product Identification Information
Brand: B&R (Bernecker + Rainer Industrie‑Elektronik GmbH)
Model: 3IF797.9‑1
Full official product name: aPCI Interface Module with Dual X2X Link Master and RS232
Place of origin: Eggelsberg, Austria
Customs HS Code: 85176290, applicable for industrial isolated communication interface circuit boards for automation equipment
Dimension and Weight
Overall mechanical dimension: 133 mm length × 76 mm height × 25 mm thickness, standard aPCI slot card dimension for internal chassis mounting
Net unit weight: 0.50 kg
Base board material: UL94‑V0 flame‑retardant FR4 multilayer printed circuit board; metal front panel with D‑Sub connector cut‑outs; no enclosure, protection grade IP20, only for installation inside closed industrial PC cabinet; external terminal blocks TB704.9 shall be ordered separately for X2X Link wiring connectionB& R Indus….

Electrical Voltage and Current Parameters
Internal supply power source: powered via aPCI slot from host Automation PC, nominal 5 VDC supply from backplane bus
Typical power consumption: 1.2 W under normal operating condition
Quiescent operating current: 240 mA at 5 VDC
All communication channels feature galvanic electrical isolation between module circuit and external field bus lines, to suppress ground loop interference and transient surge damage; RS232 port supports standard ±12 V signal level for serial communication.
Communication Performance Parameters
X2X Link interface quantity: 2 channels, master mode, B&R proprietary high‑speed fieldbus protocol, maximum transmission rate 2 Mbaud, supporting connection to distributed I/O modules and remote control stations
RS232 serial interface quantity: 1 channel, D‑Sub 9‑pin connector, adjustable baud‑rate range from 300 bps up to 115.2 kbps, supporting hardware handshake signal
Galvanic isolation test voltage: 500 V AC between internal logic side and field‑bus side
Continuous operating ambient temperature range: ‑25 ℃ ~ +60 ℃; storage and transport temperature range: ‑40 ℃ ~ +85 ℃
Allowable relative humidity: 5 % to 95 %, non‑condensing environment only.

Mechanical & Environmental Performance Parameters
Installation requirement: occupies one internal aPCI expansion slot inside B&R Automation PC; external wiring terminals TB704.9 are not included in module delivery scope and must be purchased separately for X2X bus cable termination
Vibration and shock resistance complies with IEC 60068‑2 industrial environmental test standards for cabinet‑mounted electronic assemblies.
Main Functional Characteristics
Dual independent X2X Link master interfaces enable expansion of two separate distributed I/O networks for one host automation PC, improving system layout flexibility for large‑scale automation projects; full galvanic isolation for all field‑bus ports effectively eliminates ground‑loop noise and protects internal host circuit from field‑side surge and over‑voltage disturbance; built‑in RS232 serial port supports on‑site debugging, parameter downloading and serial data exchange with legacy third‑party instruments; on‑board hardware diagnostic circuit monitors bus communication status, and reports link failure status via host system software; compact aPCI card‑type structure saves cabinet space and allows quick hot‑swap‑capable slot installation; fully compatible with B&R 2005 series CPU hardware and Automation PC platforms; configuration and diagnosis are implemented via B&R Automation Studio engineering software; since this product is obsolete, only maintenance‑oriented spare‑part supply is available; standard 1‑year warranty applies for refurbished or surplus units.
