Allen-Bradley 1734-OE2V Point I/O series analog output module

Allen-Bradley 1734-OE2V is an analog output module produced by Rockwell Automation, belonging to the POINT I/O series. The following is a detailed introduction:

Product Overview

This module has two voltage output channels and is mainly used in industrial automation control systems. It can convert the digital signal of the PLC into an analog voltage signal output to control various industrial equipment, such as motors, valves, temperature controllers, etc. It is widely used in industrial automation scenarios that require flexible configuration and low-cost solutions.

Technical Specifications

Output Characteristics

Signal Range: Supports two signal ranges of 0-10V and ±10V, which can be selected through configuration according to actual needs to adapt to the input requirements of different industrial equipment.

Output Resolution: 14 bits (13 data bits + 1 sign bit), in unipolar or bipolar mode, the resolution can reach 1.28mV/cnt, which can provide relatively accurate analog voltage output and meet the control needs of equipment with high control accuracy requirements.

Absolute accuracy: 0.1% of full scale at 25°C, with high accuracy, can ensure the accuracy of output signals and reduce control errors caused by signal deviation.

Conversion rate: The output conversion rate and the time to step response to 63% full scale are both 20 microseconds, with a fast response speed, which can timely convert digital signals into analog signal outputs, and is suitable for control systems with high real-time requirements.

Point bus current: 75mA, which is the current consumption of the module on the POINT I/O bus, used for communication and data transmission with other modules.

External DC power supply current: Under 24V DC power supply, the rated current is 35mA, the power consumption of the module is low, which can effectively reduce the overall energy consumption of the system.

Maximum power dissipation: Under 28.8V DC power supply, the maximum power is 1.0W, which can maintain low heat during normal operation and improve the stability and reliability of the module.

Electrical characteristics

Insulation voltage: When DC is 500V, the insulation resistance is above 2MΩ, with good insulation performance, which can prevent electrical interference and leakage, and ensure the safe operation of the module in an industrial environment.

Anti-noise: It can withstand 1000V, 1μS pulse noise for 1 minute, has strong anti-interference ability, can work stably in a complex electromagnetic environment, and reduce the impact of external interference on the output signal.

Environmental parameters

Ambient temperature: The operating temperature range is 0-60℃, which can adapt to the temperature conditions of most industrial sites, but additional heat dissipation or insulation measures may be required in high or low temperature environments.

Ambient humidity: The humidity range is 5%-95%, without condensation, and it can work normally in a humid environment, but the module should be prevented from direct contact with moisture to prevent short circuits and other faults.

Communication interface

Communication port 1 is RS-232, which is used to connect to the host computer and human-machine interface for programming or debugging.

Communication port 2 is RS-232/RS-485, which can be used for networking or connecting to smart instruments, inverters and other devices.

There is also a BD board to expand the communication port RS-232/RS-485, which is convenient for users to expand according to actual needs.

Mechanical characteristics

Size: The physical size of the module is 56mm×12mm×75.5mm (2.21 inches×0.47 inches×2.97 inches), which is compact and can save installation space in the control cabinet.

Weight: About 36g (1.27oz), which is light and easy to install and maintain.

Installation method: It can be fixed with M3 screws or directly installed on the DIN46277 (35mm wide) rail. The installation method is flexible and convenient for installation in different control cabinets.
