Description
B&R 5AP920.1043-K01 — Digital Input Module
Product: 5AP920.1043-K01, Digital Input Module
Manufacturer: B&R Industrial Automation (now part of ABB)
Product Line: X20 System (Modular I/O and Control)
Primary Application: A high-density, 16-channel digital input module for the B&R X20 system, designed for reliable acquisition of binary signals (ON/OFF states) from sensors, switches, and control devices in industrial automation environments.
1. Core Overview & Positioning
The B&R 5AP920.1043-K01 is a member of the high-performance X20 system of modular I/O. It is engineered for applications requiring a large number of digital input points in a compact form factor, with advanced diagnostics and fast response times.
Key Philosophy: Provides a reliable, isolated interface between field-level digital sensors and the central controller, enabling robust data acquisition for machine control, status monitoring, and safety interlocking.
2. Key Features & Functions
-
High Channel Density: 16 independent digital input channels in a single module slot, optimizing cabinet space.
-
Advanced Diagnostics: Each channel supports wire-break detection and short-circuit detection when used with compatible sensors (e.g., 3-wire PNP sensors), enabling predictive maintenance.
-
Flexible Sensor Compatibility: Supports standard 2-wire and 3-wire sensors (PNP type). The module is designed for sourcing (PNP) inputs (24V DC signal = TRUE).
-
Fast Response Times: Capable of detecting short pulses, suitable for high-speed counting and event detection applications.
-
Electrical Isolation: Features channel-to-channel and channel-to-bus isolation, protecting the control system from electrical noise and ground loops.
-
Status Indication: Per-channel LEDs provide instant visual feedback on the input state (ON/OFF) and diagnostic status.
-
Hot-Swappable: Designed for online insertion and removal in a live system (requires a compatible X20 base and system configuration), minimizing downtime.
3. Technical Specifications
-
Input Current: Typically 3-5 mA per channel at 24V DC.
-
Isolation: 500 V between channels and between channels and bus.
-
Diagnostics: Supports wire-break and short-circuit detection for 3-wire sensors.
-
Connection: Via a removable 32-pin front connector (e.g., B&R connector type).
-
Power Consumption: Approx. 100 mA from the 5V system bus (typical).
-
Mounting: Plugs into an X20 bus base module (e.g., X20BB19xx) on a DIN rail.
4. System Integration & Configuration
-
Hardware Integration: The module is installed on an X20 bus base (e.g., X20BB19xx), which is part of a distributed I/O station that includes a power supply and a communication head (e.g., X20BC0083 for POWERLINK).
-
Wiring: Field devices (e.g., push buttons, proximity sensors, relay contacts) are wired to the module’s front connector. For 3-wire sensors, the 24V supply and 0V reference are typically provided from the same source as the module’s field supply.
-
Configuration & Programming: The module is configured entirely within B&R Automation Studio. Engineers define:
-
Filter times (debouncing) for each channel or in groups.
-
Behavior for diagnostic events (e.g., generate an alarm on wire break).
-
Assignment of process variables for each channel.
-
-
Data Access: The state of each input is mapped to a bit in a process image, accessible to the PLC program running on the B&R controller (e.g., an X20 CPU).
5. Typical Applications
-
Machine Status Monitoring: Reading limit switches, door sensors, and part presence sensors.
-
Process Control: Monitoring valve positions, pump running status, and level switches.
-
Safety Interfacing: Connecting to safety relay contacts or non-safe signals for monitoring (Note: This is not a safety-rated input module for SIL/PL applications).
-
High-Density Sensor Clusters: In applications with many discrete sensors, such as packaging machines, assembly lines, and material handling systems.
