Moxa ES-1026 Safety-Reliable Ethernet Switch for Critical Sites

Moxa ES-1026 Safety-Reliable Ethernet Switch for Critical Control Sites

The Moxa ES-1026 is a 26-port unmanaged industrial Ethernet switch engineered for continuous, safety-critical operation in demanding plant environments. Designed to sustain reliable data communication across control loops, safety interlocks, and distributed I/O networks, the ES-1026 delivers deterministic performance where communication failure is not an option. With 24 × 10/100BaseTX ports and 2 × combo Gigabit uplink ports, it provides the bandwidth and port density required for modern industrial control cabinets, DCS architectures, and safety instrumented systems (SIS).

NINERMAS maintains verified stock of the Moxa ES-1026 with full pre-shipment functional testing and a 12-month warranty, ensuring your critical site receives a field-ready unit with zero compromise on reliability.

Control Cabinet Risk Reduction Strategy

In high-density control cabinets serving continuous process plants, a single point of network failure can cascade into unplanned shutdowns, safety system activations, or regulatory non-compliance events. The Moxa ES-1026 is purpose-built to anchor the Ethernet backbone of such cabinets, providing stable, low-latency switching for all connected field devices and controllers.

When integrated alongside a Moxa DR-75-24 DIN-rail power supply, the ES-1026 benefits from a clean, regulated 24 VDC source that eliminates power-line noise — a primary cause of packet loss and switch resets in electrically noisy environments. For applications requiring managed redundancy and ring topology, the Moxa EDS-516A managed Ethernet switch can serve as the backbone aggregation layer, with the ES-1026 handling edge-level device connectivity at lower cost per port.

Serial-to-Ethernet conversion is frequently required in legacy retrofit projects. The Moxa NPort 5110 serial device server bridges RS-232/422/485 instruments — such as older PLCs, flow computers, and protection relays — into the ES-1026’s Ethernet fabric without requiring controller replacement. Similarly, the Moxa ioLogik E1210 remote I/O module connects distributed digital inputs directly over Ethernet, reducing field wiring runs and eliminating signal degradation over long cable distances.

In substations and outdoor switchgear rooms where copper-to-fiber conversion is necessary to defeat ground loop interference and extend communication distances beyond 100 m, the Moxa IMC-101 industrial media converter pairs seamlessly with the ES-1026’s SFP uplink ports. For wireless backhaul in areas where cable routing is impractical, the Moxa AWK-3131A industrial wireless AP/bridge provides IEEE 802.11n connectivity with industrial-grade EMI immunity, feeding securely into the ES-1026 network segment.

Where Gigabit backbone performance is required between control room and field junction boxes, the Moxa EDS-G508E Gigabit managed switch provides the high-throughput uplink, while the ES-1026 distributes 100 Mbps connectivity to individual PLCs, HMIs, and safety controllers at the field level. The Moxa PT-7528 managed Ethernet switch — rated for IEC 61850-3 substation environments — can serve as the ring master in power utility applications, with the ES-1026 acting as a cost-effective access layer switch for non-critical monitoring nodes.

Collectively, this layered architecture — combining the ES-1026 with complementary Moxa components — creates a defense-in-depth network strategy that minimizes the risk of control interruption, signal drift, communication anomalies, and surge-induced damage across the entire control system.

Critical Industrial Safety Applications

Petrochemical & Refinery Plants: In continuous hydrocarbon processing, the ES-1026 supports real-time communication between DCS controllers, emergency shutdown (ESD) panels, and fire-and-gas detection systems. Its dual redundant power inputs and wide operating temperature range ensure network availability even during power fluctuation events common in large motor-start environments.

Electric Power Generation & Transmission: Substations and power plant control rooms demand Ethernet switches that comply with IEC 61000 EMC standards. The ES-1026’s built-in surge and ESD protection safeguards communication integrity during switching transients, lightning-induced surges, and capacitor bank operations — protecting SCADA polling cycles and protection relay coordination.

Mining & Mineral Processing: Underground and surface mining operations expose network equipment to extreme vibration, dust ingress, and humidity. The ES-1026’s metal enclosure, IEC 60068-2-6 vibration compliance, and IP30 protection make it suitable for deployment in mine control rooms, conveyor drive panels, and crusher automation cabinets.

Water & Wastewater Treatment: Municipal and industrial water treatment facilities rely on uninterrupted SCADA communication for pump control, chemical dosing, and alarm management. The ES-1026 provides the stable Ethernet backbone required for 24/7 remote monitoring, with its unmanaged simplicity reducing configuration errors that could disrupt treatment processes.

Metallurgy & Steel Manufacturing: Rolling mills, arc furnaces, and continuous casting lines generate intense electromagnetic interference. The ES-1026’s IEC 61000-4-4/5 compliance — covering electrical fast transients and surge immunity — ensures that PLC-to-HMI and PLC-to-drive communications remain error-free under these extreme electrical conditions.

Port Logistics & Marine Terminals: Crane automation, vessel traffic management, and container tracking systems require reliable Ethernet switching across large outdoor areas. The ES-1026 supports these applications in weatherproof enclosures, maintaining communication between PLCs, VFDs, and operator workstations across the terminal network.

Safety and Quality FAQ

Q1: What warranty does NINERMAS provide for the Moxa ES-1026?
All Moxa ES-1026 units supplied by NINERMAS carry a 12-month warranty covering manufacturing defects and functional failures under normal operating conditions. Warranty claims are processed with priority response to minimize downtime impact on critical production sites.

Q2: What pre-shipment testing is performed on each unit?
Every ES-1026 undergoes a full functional verification prior to dispatch, including power-on self-test, port-by-port link establishment checks, and visual inspection for physical integrity. Units that do not pass all test criteria are quarantined and not shipped. A test confirmation is available upon request.

Q3: Is the Moxa ES-1026 compatible with existing Moxa EDS-series managed switches and third-party PLCs?
Yes. As an IEEE 802.3-compliant unmanaged switch, the ES-1026 is fully interoperable with all Moxa EDS-series managed switches, as well as PLCs, HMIs, drives, and SCADA systems from Siemens, Rockwell Automation, Schneider Electric, ABB, and other major vendors. No configuration is required — plug-and-play deployment is supported in all standard industrial Ethernet topologies.
