CX1100-0001 Beckhoff 24 V DC Power & I/O Interface Module

Description

Product Model: CX1100-0001
Product Brand: Beckhoff
Product Series / Platform: CX10x0 Embedded PC / CX family

Product Features:

• 24 V DC power supply (–15% / +20%) for CX10x0 systems
• 8 kByte NOVRAM for voltage-failure-proof data storage
• Integrated 2×16 char LC display and 4+1 keypad for local diagnostics & control
• No direct I/O connector (interface only, for CPU & system bus)

Applications & Industry Context

In Beckhoff’s embedded PC ecosystem (CX1000 / CX1010 / CX1020 series), system architecture uses modular supply/interface modules to support the CPU, memory, and optional I/O expansions. CX1100-0001 serves as the foundational power / interface block for those systems when minimal external I/O is required (i.e. cases where you don’t need Bus Terminals or Fieldbus modules).

It’s particularly suited for compact or constrained automation setups where the embedded PC handles all I/O logic internally or through bus-connected modules, and the power / interface block primarily ensures stable supply and local diagnostics. In retrofits or upgrades of Beckhoff CX systems, this module may replace or be used in tandem with other variants (e.g. CX1100-0002, CX1100-0003) to match system needs.

In environments with limited rack space—like machine-mounted controllers, kiosks, or localized automation islands—CX1100-0001 offers essential system-level services without extra I/O bulk.

Technical Features & Benefits

Power & Supply Integration
This module delivers 24 V DC supply (–15% / +20%) to the CPU and system bus via internal PC/104 lines—no separate wiring is required for CPU modules.

NOVRAM for Data Persistence
When power is lost, the integrated 8 kByte NOVRAM ensures that process or configuration data is preserved safely.

Local Display & Input
It includes a 2-line × 16-character display (LC / FSTN) and a 4+1 navigation keypad (up/down/left/right + OK) to give local feedback or status messages.

Field Replaceability & Modularity
This module is part of the CX1100 family of supply/interface units. It can be swapped in the field; furthermore, other variants (0002, 0003, 0004) exist for systems requiring K-bus, IP-Link, or E-Bus connectivity.

Diagnostics & Indication
A PWR LED provides indication of supply status, and the display can show errors, warnings or system messages.

Compact & Robust Design
At around 45 mm × 100 mm × 91 mm (W × H × D) and ~180 g weight, it fits compactly in embedded racks.
It is rated IP20 and meets EMC, vibration and shock standards (per Beckhoff spec)

Technical Specifications

Installation & Maintenance Insights

• Slot & Orientation
  Ensure proper alignment in the CX series rack / bus module slot. Keyed connectors minimize misalignment.
• Power Supply Wiring
  The 24 V input must fall within the –15% / +20% tolerance. Keep wiring clean, properly rated, and fused as per system design.
• Monitoring NOVRAM Integrity
  Periodically validate stored data integrity to ensure correct failover or after power failures.
• Display / Keypad Use
  Use local display & keypad for diagnostics — e.g. check system messages, error codes, or confirm module insertion.
• Replacement / Swap-out
  Because it’s designed for field replacement in the CX series, modules can be swapped during service windows, but coordinate with system bus reset / reboot procedures.
• Environment & Cooling
  Install in a controlled panel or enclosure to avoid overheating. Keep clearance around ventilation paths.
• Surplus & Spares Strategy
  Keep spare units (same variant) especially for systems in service. Because CX1100 modules come in multiple variants, confirm you have the “-0001” type for systems that don’t require extended I/O.
