High-Accuracy Analog Output Module for Process Control AB 1756-OF4

Description

The AB 1756-OF4 High-Accuracy Analog Output Module for Process Control is a current and voltage output module designed for industrial process control systems, also known as a DAC (digital-to-analog conversion) module or 4-20mA output module, with core digital-to-analog conversion functionality to deliver precise analog signals. It features 4 independent channels that support both voltage and current output, with a voltage range of ±104V and a current range of 4-20mA. Key performance specifications include 15-bit resolution, current output accuracy of ≤0.05% full scale at 25 degrees Celsius, and channel scan times of a minimum 8ms for integer data and 12ms for floating-point data. The module draws backplane current of 200mA @5Vdc and 120mA @24Vdc, or 150mA @5Vdc and 210mA @24Vdc. Equipped with hot-swappable capability and a detachable 20-pin 1756-TBNH terminal block, it supports easy installation and maintenance without system shutdown. It holds CSA, UL, and CE certifications, and is ideal for applications such as driving frequency converters and other process control equipment that require precise analog signal output.
