Product Description
The Allen-Bradley 1734-CTM POINT I/O Common Terminal Module, part of the Bulletin 1734 series, expands POINT I/O termination capabilities when installed on a compatible terminal base (1734-TOP, 1734-TOPS, 1734-TB, or 1734-TBS), supporting 8-channel high-density modules and field device wiring management, and enabling external common connections for three-wire devices; it features a keyswitch position of 5, 1600 Vrms isolation voltage, a 10-28.8V DC or 120-240V AC supply voltage, no enclosure, C-UL-US certification, UL Listing for Class I, Division 2, Groups A, B, C, and D hazardous locations, and an operating temperature range of -20 to 55C (-4 to 131F) with 5-95% noncondensing relative humidity.
Is Your Device Showing These Signs?
The Allen Bradley 1734-CTM POINT I/O Communication Interface Module commonly experiences issues such as corrupted firmware requiring a firmware update via BootP or DHCP, failed capacitor banks causing communication faults on the POINTBus, damaged Ethernet ports preventing network connectivity, and internal component degradation leading to intermittent module failures. Resolve communication errors by verifying IP address configurations, checking Ethernet cable integrity, and ensuring proper grounding. Address module failures through component-level repair, focusing on capacitor replacement and IC chip reflowing, or consider a module replacement if damage is extensive. Always consult the Allen Bradley documentation for proper troubleshooting procedures and safety guidelines.
Technical specifications
The Allen-Bradley 1734-CTM POINT I/O Common Terminal Module expands termination capabilities for POINT I/O systems by supporting high-density modules, simplifying field device wiring (especially for three-wire devices), and providing external common connections.

Our Repair Process for the
1734-CTM
Our repair process for the Allen Bradley 1734-CTM POINT I/O Communication Interface Module begins with a thorough diagnostic assessment to identify the root cause of the failure, including verification of IP address configurations, Ethernet cable integrity checks, and grounding assessments to resolve communication errors. If corrupted firmware is detected, a firmware update is performed via BootP or DHCP. Component-level repairs are then executed, concentrating on replacing failed capacitor banks and reflowing IC chips to address communication faults and internal component degradation. Should the Ethernet port be damaged or the module sustain extensive damage, a module replacement is implemented. All repairs adhere strictly to Allen Bradley documentation for troubleshooting procedures and safety guidelines.
