Product Name
Honeywell SC-UMIX01 51307547-276 ControlEdge RTU Mixed I/O Controller Module
Product Overview
SC-UMIX01 (Part No.51307547-276) is a high-integration mixed analog & digital I/O RTU controller of Honeywell ControlEdge series. Equipped with 28 configurable I/O channels and 32-bit high-performance processor, it complies with IEC 61131-3 international programming standard, supporting local closed-loop control, process data acquisition and interlock protection. With multi-protocol communication capability and offline historical data storage function, it is widely deployed in oil & gas well sites, long-distance pipelines, pump stations, water treatment plants and power auxiliary systems for remote unattended industrial monitoring & control, serving as critical maintenance spare part for legacy Honeywell RTU & SCADA systems.
Core Functions
- 28 flexible mixed I/O channels support AI/AO/DI/DO configuration, compatible with 4-20mA, 0-10V analog signals and 24VDC digital signals, also supports HART smart instrument connection.
- IEC 61131-3 programming enables PID regulation, flow totalization, safety interlock and sequential logic control, the controller keeps running locally to guarantee process safety during communication interruption.
- Dual Ethernet + multi serial ports support Modbus TCP/RTU, DNP3, IEC 104 mainstream telecontrol protocols, realizing seamless data interaction with third-party PLC, DCS and SCADA host systems.
- Onboard large-capacity flash memory stores historical process data & alarm events offline, automatic data backfilling once network connection recovers to prevent key production data loss.
- Channel-level self-diagnosis detects short circuit, open circuit, overvoltage & overcurrent faults, supports remote fault location to greatly shorten on-site troubleshooting time.
