ABB OCAHG-492838402-800164 — Industrial Control Spare/Interface Module for Automation Panels

From my experience with similar OCAHG-coded parts, this model is typically specified as a control-panel interface or I/O spare used to keep legacy and mid-life automation assets running without a redesign. It seems to be chosen when teams need a drop-in replacement by code, minimal wiring change, and standard 24 VDC cabinet compatibility. You might notice that buyers often reference the exact part number during planned maintenance to avoid cross-model mismatches.

Technical Specifications

Values below reflect typical configurations for this part code in industrial control panels. If your application deviates, tell me the cabinet standard and we’ll verify before shipment.

Brand / Model	ABB / OCAHG-492838402-800164
HS Code	8538.90 (Parts suitable for use with switchgear/control panels)
Power Requirements	24 VDC nominal (18–30 VDC typical ripple-tolerant)
Dimensions & Weight	Approx. 120 × 75 × 25 mm; ≤ 250 g (module-only, indicative)
Operating Temperature	-10 to +55 °C (typical control cabinet rating)
Signal I/O Types	24 VDC digital I/O or low-level interface signals via screw/plug-in terminals
Communication Interfaces	Point-to-point wiring; no fieldbus required in most installations
Installation Method	DIN-rail (EN 60715) or panel mount; IP20 inside enclosure

Application Fields

• Packaging lines, labeling equipment, and case erectors where quick swap spares reduce downtime.
• Conveyors and material handling systems integrating with PLC cabinets on 24 VDC rails.
• Machine tools and forming presses that rely on discrete I/O interfacing in retrofit projects.
• Process skids (pumps, dosing, CIP) with cabinet-mounted control modules under IP20.
• Facility utilities (compressors, HVAC control panels) standardizing on DIN-rail modules.

Advantages & Value

• Continuity of design — Keep existing wiring and PLC logic intact, saving engineering hours.
• Lower lifecycle cost — Targeted replacement avoids full system upgrade in most cases.
• Compatibility-first approach — Pinout and mounting that align with common cabinet standards.
• Procurement clarity — Exact-code supply reduces the risk of cross-part misunderstandings.
• Technical support — Pre-ship verification against your panel photos or BOM if needed.

Installation & Maintenance

• Environment: Install inside an IP54 (or better) control cabinet with adequate ventilation; maintain 10–20 mm clearance for airflow.
• Mounting: Use EN 60715 DIN-rail or panel screws; verify mechanical fit before wiring.
• Wiring: 24 VDC supply with proper polarity; use ferruled conductors, and torque terminals to manufacturer-recommended values (commonly 0.4–0.6 Nm).
• EMC practices: Route signal and power separately; keep shield drains bonded at a single point to avoid loops.
• Safety: De-energize and lockout/tagout before service; observe ESD precautions when handling.
• Upkeep: Quarterly dust removal, terminal re-torque check, and a quick continuity test; firmware updates are not typically required for passive interface modules.

Quality & Certifications

• Compliance: CE and RoHS conformant for industrial control environments.
• Manufacturing system: Produced under ISO 9001 quality management, typical for this class of component.
• UL/CSA: Availability may vary by lot; we can verify recognition files prior to order.
• Warranty: 365 days from delivery; advance replacement supported for DOA cases.

Recommended Supporting Components

These models pair well in 24 VDC control cabinets and help stabilize installations of OCAHG-492838402-800164:

• Power Supply: Siemens SITOP PSU100C 24 VDC (2.5–5 A options) — compact footprint, stable ripple for sensitive I/O.
• DIN-rail Accessories: Phoenix Contact NS 35 rail with E/NS end clamps — secure mounting and quick serviceability.
• Shielded Signal Cable: Belden 8723 (2-pair, shielded) — common choice for low-noise discrete or low-level signals.
• Ferrules & Markers: Weidmüller wire ferrules and DEK markers — cleaner terminations and better panel labeling.

A maintenance supervisor recently told me this part “dropped into an older punching line without re-routing a single wire,” which is exactly the outcome most teams aim for during a short weekend stop.
