ABB 07 PA 85 Procontic Part of Composite Module

This component forms part of a composite module for ABB Procontic systems. It provides dedicated signal processing for mixed I/O functions within a single assembly. Therefore, this component suits applications requiring combined analog and digital channels.

Physical Dimensions and Weight Specifications

The ABB 07 PA 85 features a daughterboard design for plugging into a carrier module. Its board dimensions measure 160 mm in height for vertical mounting. The total depth reaches 210 mm including component clearance. Consequently, technicians can replace this part without removing the carrier from the rack.

Interface Types and Connection Layout

The ABB 07 PA 85 provides a 64-pin DIN connector for carrier interface. This connection supplies power, data, and signal routing between boards. The component carries no external field wiring terminals on its front panel. Hence, all field connections go through the carrier module instead.

Component Count and Signal Processing

This composite part contains one main board with analog and digital circuits. The board holds 4 analog input channels with 12-bit conversion. You will also find 4 digital output channels for discrete control. An onboard microcontroller handles channel scanning and diagnostics.

Energy Storage and Power Consumption

The ABB 07 PA 85 draws 80 mA from the 5V carrier supply. It also requires 60 mA from an external 24V supply for field circuits. A small capacitor bank filters noise on the analog power rails. This storage reduces measurement errors from power supply fluctuations.

Modular Design and Replacement Benefits

Users can swap this part without disturbing field wiring on the carrier. A locking lever secures the component against vibration loosening. This modular design reduces spare parts inventory costs significantly. Therefore, facilities need only stock the electronic part rather than full modules.
