ODOT DT-1314 Digital Input Module (4-Channel, 110/220VAC)

Reliable High-Voltage Signal Acquisition for Distributed I/O Systems

Key Features & Benefits

• Direct AC Signal Integration: The DT-1314 supports a wide input voltage range (Nominal 100~240VAC). This allows direct connection to AC control circuits, push-buttons, and limit switches, eliminating the cost and complexity of converting high-voltage signals to 24VDC before entering the PLC.

• Superior Channel-to-Channel Isolation: Safety and signal integrity are paramount when handling AC voltages. The DT-1314 features independent channel isolation. Each of the 4 channels is electrically isolated from the others and the internal bus, preventing cross-channel interference and protecting low-voltage control logic from high-voltage surges.

• High-Speed Redundant Backplane: As part of the D-Series family, the module utilizes a high-speed redundant backplane bus. This ensures mission-critical reliability; if one communication path fails, the backup bus takes over instantly, maintaining continuous data flow with the network adapter.

• User-Friendly Installation & Maintenance:

  • Removable Push-in Terminals: Wiring is tool-free and fast. The terminal block can be detached from the module, allowing for pre-wiring or rapid module replacement without disturbing the field cabling.

  • Clear Diagnostics: Four individual LED indicators provide immediate visual feedback on the status of each input channel, simplifying troubleshooting for maintenance teams.

• Robust Industrial Design: Engineered to operate in extreme conditions, the module functions reliably in temperatures ranging from -35°C to 60°C. It carries an IP20 rating and complies with strict EMC standards (IEC 61000-4) for ESD, Surge, and EFT protection.Application Scenarios

  The ODOT DT-1314 is perfectly suited for industries where AC control logic is prevalent:

  1. Energy & Power Monitoring: Directly monitoring the "On/Off" status of AC contactors, breakers, or mains power supplies in power distribution cabinets.

  2. Heavy Machinery Retrofits: Interfacing with legacy machines that utilize 110V/220V control logic, avoiding the need to rewire the entire machine to 24VDC.

  3. Process Control: Connecting to AC-powered level switches, flow switches, or limit switches in water treatment or chemical processing plants.

  Why Choose the DT-1314?

  By integrating the DT-1314 into your ODOT D-Series node, you achieve a cleaner panel design with fewer interposing components. It offers the perfect balance of high-voltage capability and smart, remote I/O intelligence, ensuring your automation system remains both flexible and safe.
