GE HE693ADC409

Product Name: GE HE693ADC409 Millivolt Input Module

Product Description:

The GE HE693ADC409 is a millivolt input module designed for the GE Series 90-30 Programmable Logic Controller (PLC) system. It provides four isolated analog input channels specifically for millivolt signals and strain gauge (load cell) inputs. This module allows the PLC to interface with and read signals from various low-voltage sensors and transducers. Each of the four channels can be individually configured for different input ranges.

Key Features:

• Four isolated analog input channels.
• Specifically designed for millivolt and strain gauge inputs.
• Supports bridged (load cell) strain gauges.
• Individually configurable input ranges: +/-250mV, +/-500mV, and +/-1000mV (1V).
• High input impedance (>20 Mohms).
• Common mode range of +/-12VDC.
• High accuracy.
