Description
Product Overview
The Allen-Bradley 1734-CTM is a Common Terminal Module (CTM) belonging to the Bulletin 1734 POINT I/O series manufactured by Rockwell Automation. Designed to expand the termination capacity of high-density POINT I/O assemblies, it simplifies external common connections for 3-wire field devices and higher-density 8-channel modules. The 1734-CTM mounts onto 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS terminal base units using a mechanical keyswitch position setting of 5. Featuring continuous isolation voltage rated at 250V (tested to 1600 Vrms for 60 seconds), it supports field power supply currents up to 4A per module with an ultra-compact net weight of approximately 0.04 kg (0.09 lbs).
Key Advantages
- Expanded Field Termination Capacity: Streamlines common power distribution and signal ground connections across 3-wire field devices without adding external terminal strips.
- Flexible Field Power Operations: Operates across a wide power range, supporting 10 to 28.8 V DC or 120 to 240 V AC supply voltages at 4 amps maximum continuous current per module.
- High Dielectric Isolation: Continuous 250V rating tested at 1600 Vrms for 60 seconds to ensure robust electrical isolation between adjacent control buses.
- Hazardous Location Certification: UL Listed for Class I, Division 2, Groups A, B, C, and D hazardous environments with C-UL-US approval.
- Ultra-Compact Modular Form Factor: Easily snaps into standard POINT I/O bases with keying position 5, adding functionality with a lightweight 0.04 kg (0.09 lbs) footprint.
