GE Fanuc IC697ALG320 Analog Output Module

The IC697ALG3 high-level Analog Output system for the Programmable Logic Controller (PLC) accepts digital data from the CPU or other controllers accessing the PLC backplane. This output data is converted by a Digital to Analog (D/A) converter to analog outputs of up to 10 volts full scale, or 0 to 22.5 milliamp current loop signals.

The basic converter is 16-bit resolution (1 part in 65536) with 14-bit monotonicity. Outputs are isolated from the backplane and are protected against transient and steady-state overvoltage conditions.

Analog outputs use %AQ references in the PLC. A maximum of 8K words of %AQ memory is available in the PLC. Each output channel uses one word (16 bits) of %AQ memory.

IC697ALG320 Features:

High-level analog voltage and current outputs on one module

The output module has four outputs, individually configurable for voltage or current

Provides unipolar or bipolar Analog voltage outputs up to Ç 10 volts full scale

Provides 0 to 22.5 milliamp current loop signals

Individual user scaling on each output channel

Fast update rate

No jumpers or DIP switches for the ser to configure

Calibrated at the factory with factory calibration data stored in non-volatile EEPROM memory

Removing an I/O Module IC697ALG320：

The instructions below should be followed when removing an I/O module from its slot in a rack.

Grasp the board firmly at the top and bottom of the board cover with your thumbs on the front of the cover and your fingers on the plastic clips on the back of the cover.

Squeeze the rack clips on the back of the cover with your fingers to disengage the clip from the rack rail and pull the board firmly to remove it from the backplane connector

Slide the board along the card guide and remove it from the rack.

Analog Output Diagnostics：

Diagnostic capabilities for the analog high-level output module include:

LED on modules for system status indication

Monitoring the health of the module

Detection of configuration errors

Overrange detection

Underrange detection

Open wire detection

Module LED：

There is one LED on the Analog Output module. This LED, labeled BOARD OK, flashes when the module has powered up, passed its diagnostic tests, and has configuration data for the CPU. The Board OK LED is turned on if the configurator data from the CPU is OK. It is turned off if there is a configuration error, and a fault is logged in the CPU I/O Fault Table.
