4. Product Introduction
The Horner HE693DAC410C is a 4-channel isolated analog output module for the GE Series 90-30 PLC system. It provides high-resolution ±10 V DC outputs with full channel-to-channel and channel-to-ground isolation.
Control engineers select this module for precise analog control of valves, drives, and actuators in industrial processes. The isolation reduces noise and ground loop issues. Confirm rack power budget and output scaling in your PLC program before installation.
