E3EC HENF315125R1 Industrial Control Module
This module serves as a critical interface for industrial automation systems requiring precise relay control and Modbus communication. Commonly deployed in manufacturing lines, HVAC systems, and process control environments, its 6-channel 2A relay output handles moderate electrical loads while maintaining signal integrity through galvanic isolation between circuits.

Application Context
We’ve seen this module perform reliably in applications like conveyor belt sequencing at automotive plants, where its relay contacts switch 24V solenoids with millisecond precision. One customer in chemical processing used it to interface Modbus RTU sensors with their Siemens S7-1200 PLC system, appreciating the built-in optical isolation between channels.
Our inventory includes complementary components like ABB AC500 series PLCs, GE VMIVME modules, and Honeywell DCS interface cards. For example, pairing this E3EC module with our stock 3BHE040375R1023 analog input card creates a complete control solution for temperature regulation systems.
Our Service Commitment
While E3EC offers a 2-year manufacturer warranty, we provide additional 1-year coverage on all our industrial automation parts. With 16 regional warehouses across 6 countries and real-time inventory tracking, we typically ship within 24 hours of order confirmation. For urgent needs, our WhatsApp support line (+86 190-6659-1275) connects directly to live technical support.
For current pricing and availability, please contact our sales team at abbdcs36@gmail.com. We maintain active partnerships with major brands including ABB, GE, and Siemens, allowing us to offer competitive pricing on both standard and obsolete components.
“Personally, I’ve found this module works better than similar offerings from Phoenix Contact in high-vibration environments – the screw terminals hold connections more securely during equipment transport.”
