Allen Bradley 1756-L85ES

The Allen Bradley 1756-L85ES recommended by Hanyite is a HART protocol analog input module suitable for Rockwell Automation 1756 series PLCS. It can be used for signal monitoring in industrial automation control systems because it has intelligent diagnosis and high-precision data acquisition capabilities. The feedback from customers on Hanyite has all been very positive.

Core Functions and Technical Features

The Allen Bradley 1756-L85ES is compatible with the high-speed addressable remote sensor communication protocol and can conduct two-way digital communication with HART intelligent instruments. Digital signals are superimposed on 4-20mA analog signals to achieve equipment parameter configuration, status monitoring and fault diagnosis. The 8 non-isolated single-ended analog input channels support the 0-20mA and 4-20mA signal ranges, with 16-bit resolution and an accuracy of 0.1% of the full scale (@20°C), and a temperature drift coefficient of 0.05% of the full scale (0-55°C). The product is equipped with a built-in local microprocessor to support fault diagnosis functions, such as disconnection detection, over-range/under-range alarm and remote transmitter alarm. Eight red fault indicator lights, eight yellow channel indicator lights and one green power indicator light can display the module and channel status in real time. Customers can identify problems at any time during the usage process to reduce losses. The Allen Bradley 1756-L85ES also supports unipolar and bipolar signal configurations, allowing for independent configuration of the data format, input range and filter parameters for each channel. Compatible with ControlNet and Ethernet/IP communication adapters (models such as 1756-IF16IH are required), supporting ControlNet 5.1 and above versions as well as Ethernet 4.2 and above versions. If technicians find any problems, they can contact Hannit immediately.

Hardware Specifications

Application

Allan Bradley 1756-L85ES is applicable to process control systems in industries such as oil and gas, chemical engineering, energy and water treatment, which require intelligent device monitoring and location analog signal acquisition. The HART protocol enables remote device management and real-time monitoring of process metrics such as pressure, temperature and flow rate. This helps to enhance system automation and maintenance efficiency. If technicians have any questions, please feel free to contact Hanyite at any time.
