The Measurement Computing / IOtech DBK203 is a screw-terminal adapter module that bridges field wiring to Measurement Computing data acquisition systems. Its pull-out drawer design provides direct access to twelve terminal blocks and a 40-pin P3 header, streamlining signal routing and reducing installation time.
Technical Specifications
Connectors & Terminal Blocks
• P1: DB37 (Male) — Analog Input
• P2: DB37 (Male) — Digital I/O
• P3: Internal 40-pin header — Digital I/O and Analog Out
• P4: 100-pin connector — Aggregates signals from P1, P2, and P3
• TB1–TB4: Pulse/Frequency/Digital I/O (P3 connection)
• TB5–TB8: Digital I/O (P2 option)
• TB9–TB12: Analog Input (P1 option)
Electrical
On-board RC filter socket locations are available for custom RC filter networks on P1 Analog Input channels.
– Key Features
• Pull-Out Drawer: Enables convenient access to all twelve terminal blocks and the 40-pin header without removing the module from its enclosure
• Shielded Metal Enclosure: Facilitates direct mounting to other DBK signal conditioning and expansion modules
• Multiple Connection Options: Redundant pathways via screw terminals and connectors reduce wiring complexity
• Modular Architecture: Integrates with the DBK200 Series ecosystem
– Typical Applications
Field signal termination and conditioning for multi-channel data acquisition systems. Terminal blocks support analog input measurement, digital I/O control, and pulse/frequency monitoring across distributed sensor networks.
– Compatibility & Integration
Designed for Measurement Computing DaqBoard/2000 Series and DaqBook/2000 Series devices. Compatible with DAQami and TracerDAQ software environments. The DBK203A supersedes this model and omits the slide-out drawer. Avoid simultaneous use of both connector and terminal block paths for the same signal to prevent conflicts. Observe ESD precautions and power-down systems before making connections.
