GE IC693ALG390C Analog Output Module

This analog output module converts digital values into proportional voltage or current signals. It controls actuators, valves, and drives in a Series 90-30 system. You will install this module in any I/O slot of the main rack.

Key Technical Specifications

The IC693ALG390C provides four analog output channels with 12-bit resolution. Each channel operates as either voltage or current output. The module also includes individual channel configuration for flexible field applications.

Hardware Architecture and Signal Conversion

The IC693ALG390C uses a 12-bit digital-to-analog converter for each output channel. Thirty-six precision resistors set gain and offset for all four channels. Eighteen filtering capacitors remove ripple from each analog output. The module also includes a voltage reference with ±0.1% stability.

Interface and Connectivity

One 20-position removable terminal block connects analog wiring to field devices. Each output channel includes dedicated positive and common terminals. A 24-pin backplane interface receives digital values from the CPU. The module requires an external 24V DC supply for the analog circuits.

Practical Installation Notes

Install this output module in any I/O slot of a Series 90-30 rack. The IC693ALG390C needs DIP switch configuration for range selection. Always use shielded twisted-pair cable for 4-20 mA current loops. Verify the load impedance matches the selected output range for proper operation.
