OKOS AL8XGTE-3 – Compact 8‑channel I/O Module for PLC/SCADA Expansion

The OKOS AL8XGTE-3 is designed for straightforward expansion of control panels where you need reliable, space‑saving I/O. From my experience, it fits well in brownfield retrofits and quick line upgrades—situations where you don’t want to overhaul the PLC, just add points cleanly. The module typically runs on 24 VDC, mounts on a standard DIN rail, and communicates over a mainstream industrial protocol, making it easy to drop into existing cabinets without drama.

You might notice that its channel density and simple wiring approach reduce panel clutter. One thing I appreciate is the pragmatic design: clear status LEDs, pluggable terminals, and a communication port that most technicians are already familiar with. In many cases, that means faster commissioning and fewer support calls later.

Order Placement Process & Guarantees

• Warranty: 365 days from delivery.
• Lead time: 1 week for in‑stock items; no more than one month at the latest.
• Payment: 50% advance payment; full payment before delivery.
• Express delivery: FedEx, UPS, or DHL, per your preference.

Key Features

• 8-channel I/O density: Ideal for small expansions where a full rack isn’t justified.
• 24 VDC cabinet-friendly power: Typically powered from the control panel’s standard 24 VDC bus.
• DIN-rail installation: Quick mount on EN 60715 rails; tidy cable routing with pluggable terminals.
• Status LEDs per channel: Faster diagnostics during commissioning and maintenance.
• Industrial comms: Generally offered with a common field protocol for PLC/SCADA connectivity (e.g., Modbus RTU over RS‑485 in many cases).
• Ruggedized for panels: Built to handle typical cabinet temperatures and electrical noise found in factory environments.

Technical Specifications

Application Fields

• Packaging lines and pick‑and‑place cells needing incremental I/O without a full PLC upgrade.
• Water/wastewater skids where remote I/O nodes simplify field wiring runs.
• Building services panels (fans, dampers, interlocks) where 24 VDC signals dominate.
• Process OEM equipment retrofits where downtime windows are short and wiring must be intuitive.

A maintenance supervisor at a food plant told us the compact module “saved a whole row of terminals” during a weekend retrofit—exactly the kind of small win that makes Monday start smoother.

Advantages & Value

• Compatibility: Works with common PLC/SCADA platforms via standard industrial protocols, reducing integration risk.
• Cost control: Adds points only where you need them—no oversized racks or unused slots.
• Faster deployment: DIN-rail, labeled terminals, and channel LEDs typically cut commissioning time.
• Spares strategy: A single, compact module is easier to stock and swap, keeping MTTR low.

Installation & Maintenance

• Mount on EN 60715 DIN rail inside a metal enclosure; provide ventilation space and avoid heat sources.
• Power from a regulated 24 VDC supply; leave headroom (typically 20–30%) for inrush and future expansion.
• Use ferrules and proper wire gauges for pluggable terminals; observe polarity and shielding for RS‑485 networks.
• Follow best practices for earthing and segregation from high‑noise cables (VFD outputs, contactor coils).
• Routine checks: verify terminal torque, inspect for dust buildup, and confirm channel status LEDs during walkdowns.
• If the installed variant supports firmware, plan periodic updates during scheduled downtime and back up configuration.

Quality & Certifications

• Compliance typically available: CE and RoHS for industrial control equipment.
• UL/cUL availability may depend on specific production batches or regional variants—please confirm at order.
• Manufacturer quality system commonly aligned with ISO 9001 practices.
• Warranty: 12 months (365 days) from delivery.
