Overview
The Allen-Bradley 1734-VTM is a single-slot voltage terminal module designed for expansion of signal termination capability within POINT I/O systems. This module enables cost-effective, high-density connections for voltage-based I/O applications in CompactLogix and distributed automation environments. Compatible with terminal bases including 1734-TB, 1734-TBS, 1734-TOP, and 1734-TOPS, the 1734-VTM provides scalable termination architecture for industrial control panels.
Key Features
- Eight voltage signal points — accommodates 0 to 7 voltage output connections at the common terminals
- Single-slot 12 mm width — optimized for compact panel layouts and high-density terminal arrangements
- Open-style, DIN rail mount — simplifies installation in standard electrical enclosures
- Removable terminal block (RTB) — field-replaceable terminal blocks reduce downtime during maintenance
- Industrial certifications — CUL, GOST, KC, and UL listed for global deployment
- Isolation tested to 1600 Vrms — ensures safety compliance in demanding electrical environments
