Acquisition Logic AL81G – Multi‑Channel Industrial Data Acquisition for Reliable, Networked Measurements

The Acquisition Logic AL81G is built for teams that need stable, multi‑channel signal acquisition in production lines, test benches, and R&D setups. From my experience, the AL81G typically fits best where you want PC‑independent measurements with clean analog front‑ends, solid triggering, and Ethernet connectivity, without overcomplicating the control architecture. You might notice that it balances precision with practicality—signal integrity, straightforward wiring, and manageable software integration matter more than flashy specs in most cases.

In many cases, engineers deploy the AL81G as a compact DAQ node to capture analog voltages alongside digital I/O and a hardware trigger/clock—streaming results over standard Ethernet to a workstation or data server. It seems to be a smart pick for retrofits and expansions where cabinet space and wiring discipline are non‑negotiable.

Key Features

• Multi‑channel analog acquisition – Designed for precision voltage inputs across several channels, typically supporting single‑ended or differential wiring for cleaner measurements.
• Integrated digital I/O and hardware trigger – Discrete lines for start/stop, event flags, and external clock/trigger help synchronize with PLCs, motion systems, or other test instruments.
• Ethernet connectivity – 10/100/1000BASE‑T networking for deterministic data exchange on plant or lab networks; easy to segment via managed switches.
• Rugged, cabinet‑friendly design – Typically DIN‑rail or panel‑mountable with locking connectors and grounded mounting points to curb noise pickup.
• Flexible input ranges – Supports common ±10 V and other standard ranges, so you can standardize probes and wiring across stations.
• Local buffering and stable streaming – Helps ride out short network bursts or latency, reducing the risk of data gaps during long runs.
• Wide DC power tolerance – Works from a typical 24 VDC cabinet supply (wide input range), which simplifies integration in existing panels.
• Serviceable firmware – Field‑updatable firmware for security patches or feature improvements without taking systems offline for long.

Technical Specifications

Application Fields

– End‑of‑line test stands for automotive and electronics assemblies
– Condition monitoring on rotating equipment and fixtures (voltage/logic capture)
– Bench R&D measurements where synchronized analog + digital timing is needed
– Machine retrofits that require Ethernet‑based DAQ without redesigning the PLC layer
– Academic and pilot labs consolidating scattered sensors into a single network node

Advantages & Value

• Reliability under real‑world noise – Shield‑aware input topology and solid grounding make a difference when cabinets sit beside drives or welders.
• Interoperability – Standard Ethernet and common protocol support simplify IT approvals and SCADA/LIMS connections.
• Lower lifecycle cost – Uses your existing 24 VDC power and wiring conventions; firmware updates extend usable life.
• Scalable deployment – Add nodes per machine or per line; data streams centralize nicely on managed switches.
• Technical continuity – From my experience, the AL‑series design philosophy stays consistent, easing spares and training.

Installation & Maintenance

• Cabinet & mounting – Install in a ventilated control cabinet (EN 60715 DIN‑rail or panel). Keep away from high‑EMI sources or use segregated wiring ducts.
• Power & grounding – 24 VDC supply with protective earth; route analog commons to a single star ground point to reduce ground loops.
• Wiring – Use shielded twisted pair for analog lines; land shields at one end only. Separate AI, DI/DO, and power harnesses by at least 100 mm where possible.
• Networking – Place on a managed switch/VLAN for deterministic performance. QoS on measurement ports helps under heavy plant traffic.
• Safety – De‑energize before servicing. Verify input range/jumper settings prior to bringing sensors online.
• Routine maintenance – Quarterly connector inspection and dust cleaning; back up configuration; apply firmware updates after validation; recalibrate to your quality schedule if used for compliance data.

Recommended Accessories & Supporting Components

• 24 VDC industrial power supply – A slim DIN‑rail PSU (for example, 60–120 W) provides clean power headroom for the AL81G and any sensors.
• Shielded analog input cabling – Low‑noise, twisted‑pair cable with drain wire; crimped ferrules improve terminal reliability.
• Terminal breakout/adapter – A DIN‑rail terminal breakout eases field wiring and keeps service loops tidy.
• Industrial Ethernet switch – Managed switch with VLAN/QoS for isolating measurement traffic; choose metal housing for cabinet installations.
• Panel labeling set – Channel ID tags reduce confusion during maintenance and audits.

Quality & Certifications

The AL81G is typically supplied with CE conformity and RoHS compliance; many deployments integrate within ISO 9001 quality systems. UL/CSA considerations usually depend on the final panel assembly and power distribution. Warranty coverage is 365 days from delivery under our standard terms.
