Allen-Bradley 1734-VTM Voltage Terminal Module

Allen-Bradley 1734-VTM Voltage Terminal Module Configured for isolated 24 VDC power distribution to downstream I/O assemblies in POINT I/O networks, the Allen-Bradley 1734-VTM (1734-VTM Voltage Terminal Module) provides direct electrical execution. The module distributes isolated field power to connected POINT I/O modules, supports segmented power architecture, and interfaces with the PointBus backplane through a DIN rail mounted form factor. Suffix Breakdown & Model Matrix The supplied documentation identifies 1734-VTM as a single catalog number. No official suffix breakdown or option matrix is specified in the provided data. Hardware Specifications Parameter Specification Model 1734-VTM Brand Allen-Bradley Product Type Voltage Terminal Module Product Family POINT I/O Module Width 12 mm Dimensions Width: 12 mm Operating Temp 0 to 60 deg C Storage Temp -40 to 85 deg C Power Consumption Typical 3.8 W Field Power Input 24 VDC (18-30 VDC), non-isolated Isolated I/O Output 24 VDC Maximum Output Current 8 A at 40 deg C Supported Modules Up to 8 POINT I/O modules Connection Type Removable screw terminal block Relative Humidity Up to 95% non-condensing Mounting Method DIN rail mounted Certifications c-UL-us, ATEX, IECEx, CE (batch dependent) EtherNet/IP Network Segmentation and I/O Density Scaling The 1734-VTM is installed within POINT I/O assemblies to create isolated field power segments while maintaining PointBus communication continuity. By supplying isolated 24 VDC output to as many as eight downstream modules, the terminal module allows I/O group expansion without requiring separate external distribution blocks. This architecture supports modular I/O density scaling and simplifies power domain separation within distributed EtherNet/IP-based POINT I/O installations. Frequently Asked Questions Q: Does the 1734-VTM provide signal isolation or power isolation? A: The module is specified as providing isolated 24 VDC I/O power distribution to downstream POINT I/O modules. It is intended for power segmentation within the I/O assembly. Q: How many POINT I/O modules can be powered from one 1734-VTM? A: The specified capacity is up to 8 downstream POINT I/O modules per 1734-VTM. Q: Can the 1734-VTM be mounted directly on a DIN rail? A: Yes. The module is designed for DIN rail installation as part of a POINT I/O assembly. Field Installation Guidelines Verify incoming field power is within the specified 18-30 VDC input range before energizing the module. Install the module on a properly grounded DIN rail according to POINT I/O assembly requirements. Tighten field wiring connections according to the terminal block manufacturer's recommendations. Route power conductors separately from high-noise motor and drive cables where possible. Maintain adequate spacing and ventilation around the assembly when operating near the maximum current rating. Confirm total downstream load current does not exceed the specified 8 A output capability. Inspect terminal connections periodically for loosening caused by vibration or thermal cycling.
