→ Water & Wastewater Treatment
Monitor pump motor status, valve actuator positions, and equipment operational states in treatment facilities. The module's extended temperature range and humidity tolerance ensure reliable operation in challenging environmental conditions typical of water treatment applications.

Technical Specifications & Selection Guide

Selection Criteria: Choose the IC694MDL240 when your application requires monitoring of AC voltage states (on/off detection) rather than precise voltage measurement. For analog voltage measurement applications, consider the IC695ALG series analog input modules. When monitoring DC voltage signals, select the IC694MDL series DC input modules instead.

Extended System Integration Capabilities

RX3i Platform Compatibility: The IC694MDL240 integrates seamlessly with all GE PACSystems RX3i CPU modules including the IC695CPU310, IC695CPU320, and IC695CPE400 processors. Configuration is performed through Proficy Machine Edition software, enabling rapid parameter setup and diagnostic access.

Distributed I/O Architecture: Deploy the module on local or remote I/O racks using IC694CHS series backplanes and IC695LRE expansion interfaces. This flexibility supports both centralized and distributed control architectures based on application requirements and wiring economics.

Network Integration: Combine with IC695ETM001 Ethernet modules or IC695PBM300 Profibus interfaces to enable remote monitoring, SCADA integration, and enterprise-level data collection from distributed voltage monitoring points.

Complementary Modules: Pair with IC694MDL series discrete output modules for complete control loops, IC695ALG analog modules for process variable measurement, and IC694PWR power supply modules for robust system power distribution.

Frequently Asked Questions

Can this module monitor both 120V and 240V circuits simultaneously on different channels?
Yes, the IC694MDL240 supports mixed-voltage monitoring with each channel independently handling any voltage within the 0-264 VAC range. No configuration changes are required when connecting different voltage levels to separate channels.

What is the minimum voltage required for reliable input state detection?
The module's ON-state threshold is typically 79 VAC minimum for 120V nominal operation and 158 VAC for 240V operation. Consult the technical datasheet for precise threshold specifications and hysteresis characteristics.

Does the IC694MDL240 require external power supplies for input sensing?
No external power is required. The module draws all necessary operating power (120 mA maximum) from the RX3i backplane 5 VDC supply. Input sensing is performed directly from the monitored AC voltage sources.

How many IC694MDL240 modules can be installed in a single RX3i rack?
Module quantity depends on backplane slot availability and total power budget. A standard 10-slot IC694CHS392 backplane can typically support 6-8 input modules depending on CPU selection and other installed modules. Consult the RX3i system planning manual for specific configurations.

Is the module compatible with legacy GE Series 90-30 control systems?
No, the IC694MDL240 is designed exclusively for PACSystems RX3i platforms and is not backward-compatible with 90-30 systems. For 90-30 applications, consider the IC693MDL series AC input modules.

What diagnostic information does the module provide to the CPU?
The module reports channel status, module health, and fault conditions to the RX3i CPU through standard I/O diagnostics. This information is accessible through Proficy Machine Edition for predictive maintenance and system monitoring applications.
