Allen-Bradley 1734-CTM Point I/O series terminal module

Allen-Bradley 1734-CTM is a universal terminal module in Rockwell Automation's Point I/O series, used to expand the wiring capacity and flexibility of the system. The following is a detailed introduction:

Product Overview

1734-CTM is a passive module in the Point I/O series. Its main function is to provide additional wiring terminals for digital or analog I/O modules to support more complex wiring requirements. It allows users to connect the cables of field devices to the module, and then communicate with the main controller through internal circuits, simplifying the system integration process.

Technical Specifications

Physical Characteristics

Dimensions: approximately 49mm (width) × 12mm (depth) × 144mm (height), compatible with other Point I/O modules.

Weight: approximately 63.8 grams.

Installation method: supports DIN rail installation, horizontal or vertical layout.

Environmental parameters

Operating temperature: -20°C to 65°C (-4°F to 149°F).

Storage temperature: -40°C to 85°C (-40°F to 185°F).

Humidity: 5% to 95% relative humidity (non-condensing).

Vibration resistance: 5g (10-500Hz).

Shock resistance: 30g.

Terminal specifications

Type: Removable cage clamp terminal (Cage Clamp), supporting quick wiring.

Wire diameter range: 0.25 to 2.5mm² (22-14AWG).

Number of terminals: 8 terminals are provided per module.

Wire type: Supports solid or stranded copper wire (requires 75°C rated insulation).

Features

Modular expansion

Can be used in combination with 1734 series communication adapters (such as 1734 - AENT) and I/O modules (such as 1734 - IB8, 1734 - OB8) to expand the system's I/O points and wiring capabilities.

Simplified wiring

By centrally connecting the cables of field devices to the CTM module and then communicating with the main controller through the internal bus, the number of cables in the control cabinet is reduced, and the wiring is neat and maintainable.

Plug and Play

Supports hot swapping, and the module can be replaced while the system is running without powering off, reducing downtime.

Mechanical keying

The module is designed with a keyway to prevent mis-insertion to ensure the correct installation position and avoid failures caused by misoperation.

Compatible with terminal blocks

Can be used with 1734-RTB (removable terminal block) to further enhance wiring flexibility.

Typical application scenarios

Distributed I/O system: Expand I/O connection points in control cabinets with limited space.

Complex industrial environment: Reduce cable interference and improve system reliability through centralized wiring.

Frequent maintenance scenarios: Support fast module replacement and shorten fault repair time.

Notes

When using, make sure that the power supply type (DC/AC) of the CTM module is consistent with that of the adjacent I/O module.

The tightening torque of the terminal is 0.6N・m, and appropriate tools must be used to avoid damage.

The total number of expansion modules is limited by the load capacity of the communication adapter and needs to be configured in the product manual.
