AO845 AO845A Analog Output Module

Description

Overview

Essential details：DO820 Digital Output Relay 8 ch

The AO845/AO845A Analog Output Module for single or redundant applications has 8 unipolar analog output channels. The module performs self-diagnostic cyclically. Module diagnostics include:

• External Channel Error is reported (only reported on active channels) if the process power supply that supply voltage to output circuitry is too low, or the output current is less than the output set value and the output set value > 1 mA (open circuit).
• Internal Channel Error is reported if the output circuit can not give the right current value. In a redundant pair the module will be commanded to error state by the ModuleBus master.
• Module Error is reported in case of Output Transistor Error, Short Circuit, Checksum Error, Internal Power Supply Error, Status Link Error, Watchdog or Wrong OSP behavior.

Features and benefits

• 8 channels of 4…20 mA
• For single or redundant applications
• 1 group of 8 channels isolated from ground
• Analog inputs are short circuit secured to ZP or +24 V
• HART pass-through communication

The AO845A analog output module is a high-performance analog output module with a compact design that can process analog signals quickly and accurately. The module has eight unipolar analog output channels, each with an independent output set point and an open output function with a set point >1mA.

The AO845A analog output module uses cyclic self-diagnosis technology to detect and report both external channel errors and internal channel errors. When the module bus master detects an error, the command module enters the error state. In addition, the module also has the characteristics of high precision, low noise and low drift, which can provide accurate analog signal output.

In the automation control system, AO845A analog output module is widely used in various occasions requiring analog signal output, such as motor control, sensor signal output, etc. It can be used in conjunction with other sensors, actuators and other devices to achieve precise control and fast response.

In summary, the AO845A analog output module is a powerful and easy to use analog output module, suitable for a variety of automatic control system analog signal output needs. When using the module, users should fully understand its technical specifications and parameters to ensure the stability and reliability of the system.
