ANC-100e: DH+ to Ethernet Bridge for Industrial Automation
A Better Alternative to 1756-DHRIO & ProSoft
The ANC-100e gateway provides seamless Ethernet/IP communication to legacy Allen-Bradley DH+ networks. It connects modern PanelView Plus HMIs, SCADA (Ignition, FactoryTalk, Wonderware), and engineering PCs directly to legacy PLC-5 and SLC 5/04 processors with zero ladder logic changes.
- Hardware Replacement: Replaces obsolete 1756-DHRIO, 1756-ENBT racks, and ProSoft AN-X2 modules for DH+ SLC5/04 and PLC5 processor communications.
- Cost-Effective Gateway: Standalone hardware at $1,195 USD—eliminates the need for separate chassis or expensive surplus modules.
- Smart Auto-Detection: Integrated Auto DH+ Baud Rate (57.6k / 115.2k / 230.4k) and auto-polarity correction.
- Industrial Protection: DIN-rail mountable with 400V continuous isolation and TVS surge protection.
