Function

HART protocol support: It supports the HART protocol and enables two-way communication with intelligent devices (such as transmitters) to obtain device status, diagnostic information, etc.

High-resolution input: 16-bit resolution, supporting 0-20 mA and 4-20 mA current signals, suitable for high-precision analog signal acquisition.

Alarm function: Supports over-range, under-range, disconnection detection, local fault and remote fault alarm, enhancing system reliability.

Filter support: Each channel is equipped with a fixed hardware filter and an optional digital filter to optimize signal processing.

Flexible configuration: Supports independent programming for 2 groups (0-3 and 4-7 channels) to meet different application requirements.

No patch cord design: Fully configured through software, no physical patch cords or switches are required.

Modular design: Supports Removal and Insertion Under Power (RIUP), allowing modules to be replaced during system operation.

Compatible communication adapters: Supports ControlNet, EtherNet/IP and Profibus (only 1794-APBDPV1) adapters.

Application scenarios

Process control: It is used in industries such as chemical engineering, petroleum and natural gas, and water treatment to collect analog signals such as pressure, temperature, and flow rate.

Distributed Control System (DCS): Integrated into the PLC system, it monitors and collects data from intelligent devices and supports HART protocol communication.

Factory automation: Applicable to sensor signal acquisition on production lines, such as flowmeters and level gauges.

Energy management: Used for monitoring analog signals in power or public utilities.

Food and beverage: Collect analog signals from packaging or filling equipment to ensure precise control.

Advantage Products:

All items are Distributor Ready-stock Genuine Brand-new Supplying, please inform us if the other conditions are needed, Used, Open-box, Refurbished, etc.
