Product Short Description
The GE HE693ADC410 is a high-performance, 4-channel isolated analog input module designed for the GE Series 90-30 PLC system (Horner APG product line). It converts ±10VDC analog signals from field sensors into high-resolution digital values for the PLC CPU, ensuring accurate and reliable data acquisition in electrically noisy industrial environments. The module provides 2000VDC galvanic isolation between channels and to ground, protecting the control system from voltage spikes, ground loops, and EMI/RFI interference. It integrates on-board filtering, fault detection, and programmable alarm setpoints, making it ideal for precision process monitoring and control applications.

Key Features
- High-Isolation Design: Delivers 2000VDC galvanic isolation between all channels and ground, eliminating ground loops and protecting the PLC from high-voltage transients and electrical noise.
- 14-Bit High Resolution: Provides precise analog-to-digital conversion with 14-bit resolution, ensuring accurate measurement of low-level sensor signals for tight process control.
- ±10VDC Universal Input: Compatible with a wide range of industrial sensors (pressure, temperature, flow, level) that output standard ±10VDC analog signals.
- Programmable Alarm Setpoints: Each channel features a user-configurable setpoint (via PLC %AQ registers). When the input exceeds the setpoint, a corresponding discrete %I alarm bit activates for immediate fault notification.
- Dual Filtering System: Combines hardware Bessel filtering (1kHz) and programmable digital filtering (1–128 samples) to suppress electrical noise and stabilize fluctuating sensor signals.
