GE IC670ALG310 Analog Output Module

INTRODUCTION

The 8 Point Isolated Analog Voltage-source Output Module (IC670ALG310) accommodates eight voltage outputs in two isolated groups of four. It provides eight channels of analog voltage outputs with user–configurable scaling for each channel.

Supports 8 channels of output voltages ranging from –10V to +10V with 14-bit resolution. 

Output overrange provided for up to approximately 10.25V. 

Uses both word and bit data types. 

Can be field-recalibrated or reset to factory calibration. All calibration data is stored in FLASH memory. 

Individual channel configuration including output range and scaling parameters. 

Reports Under/Overrange faults

LEDs

A single indicator shows module status: 

ON: normal operation 

Intermittent flashing: module fault 

OFF: No backplane power, no user power, or fatal fault

The 8 Point Isolated Analog Voltage-source Output Module provides the following alarms: 

Over/Underrange: if an engineering units value sent by the host has resulted in an output value within approximately 50mV of the module’s maximum or minimum.

Uncalibrated Module

Host Interface

The 8 Point Isolated Analog Voltage-source Output Module uses the following types of data: 

0–8 words of analog output data 

0–3 bytes of discrete input data for module and channel status. 

0–2 bytes of discrete output data for clearing alarms.

Module Features

Channel Active

Each channel can be configured as either active or inactive. If a channel is Inactive, its output is 0V and the analog output data for the channel is not used. Alarm (optional discrete input) data for the channel is not updated for a channel that has been configured as Inactive. If the configuration of a channel is changed from Active to Inactive, the module stops updating its alarm data. Pre-existing alarms can still be cleared using the module’s configured discrete output bits.

Local Output Defaults

In addition to being able to configure data defaults of zero or hold last state for the module’s data in the BIU, local output defaults for the module are also configurable. These module local defaults determine whether the module will set the actual output voltages to zero volts or hold their last values if a module error occurs.

Functional 

Enhanced Diagnostic Functions: Easily detects over-range and under-range conditions, user power failure and uncalibrated modules to ensure stable system operation.

Alarm Functions: With alarm functions that can be set by the user for different events. When the output value does not meet the 50 mV requirement of the module's maximum or minimum output settings, the module will treat the output value as under-range and over-range and trigger an alarm.

Communication Interface: Usually has a communication interface that allows data exchange and communication with the control system or other devices.

Built-in diagnostic and self-test functions: Used to detect module status and performance problems to ensure proper operation of the module.

High reliability and vibration resistance: Designed for use in industrial environments with high reliability and vibration resistance to ensure stable operation under harsh conditions.
