Main Features and Advantages
High-density wiring interface for POINT I/O systems: The 1734-VTM is purpose-built to maximize the wiring density of 8-channel POINT I/O modules such as the 1734-IB8 and 1734-OV8 -8-9. By providing eight voltage terminals in a single 12 mm wide slot, it eliminates the need for external terminal blocks or complex junction boxes when connecting multiple field devices to a common voltage source. The 1734-VTM is installed on a 1734 terminal base unit and uses a removable terminal block (RTB) for quick and convenient wiring -10-8.
Robust modular design with easy installation: The 1734-VTM features a module locking mechanism and interlocking side pieces that allow it to slide together with adjacent modules for a secure, vibration-resistant assembly -10-8. The module supports Removal and Insertion Under Power (RIUP), enabling replacement while the system remains operational—a critical advantage for minimizing downtime in continuous process applications -4. The mechanical key-switch positions (5 available) prevent incorrect module installation, ensuring system integrity -8-10.
Enhanced field power distribution and organization: The 1734-VTM serves as a central distribution point for field power, with the ability to handle both DC and AC supply voltages -8-11. It supports a field power current of 4 A per module, providing ample capacity for powering multiple sensors, actuators, and other field devices -6-8. The module’s 8 voltage outputs, each paired with a corresponding common terminal, simplify the wiring of 2-wire and 3-wire proximity sensors and other field devices in both sink and source configurations -10-7.
Hazardous location approval and wide operating range: The 1734-VTM is approved for use in hazardous locations with Class I, Division 2 certification, making it suitable for installation in oil and gas, chemical, and other potentially explosive environments -8-10. Its wide operating temperature range of -20°C to +55°C and high vibration/shock tolerance ensure reliable performance in demanding industrial settings -1-8.
