Internal Design and Analog Conversion

This analog output module uses four independent 12-bit DACs for precision control. Voltage-to-current converters allow each channel to output current or voltage. The GE IC693ALG392B stores the latest digital value for each channel in onboard buffers. Four 10 µF capacitors filter output signals for smooth analog response. The module updates all four channels every 10 milliseconds. Consequently, this unit delivers accurate analog control for valves and actuators.

Installation and Wiring Guide

First, mount this module into any Series 90-30 rack slot. Next, connect a 24 V DC field supply to the designated terminals. Then, wire your load devices to the output terminals (channels 1-4). Configure each channel’s output type using software settings. Use shielded twisted-pair cables for long cable runs over 30 meters. The module provides LED indicators for module status and field power. This analog output module works with all Series 90-30 CPU models including 311, 331, 341, 363, and 364. Always verify the load resistance matches your selected output mode before operation.
