Description
ACC-5595-217 Industrial Interface Module – Reliable I/O/Communication Accessory for Control Systems
The ACC-5595-217 is part of the ACC-5595 family commonly used as an interface or expansion accessory inside PLC/DCS cabinets. From my experience, it’s typically applied as a drop-in replacement to restore serial/fieldbus connectivity or extend I/O functions without redesigning the panel. You might notice that integrators value it for its straightforward wiring and the way it fits into existing layouts with minimal changes. For maintenance teams, it seems to be a practical spare—swap it, tighten the terminals, run a quick loop test, and you’re back online.

Technical Specifications
Notes: Fielded units can vary by OEM revision. The values below reflect common configurations encountered in industrial panels.
| Model | ACC-5595-217 (ACC-5595 series) |
| HS Code | 8538.90 (Parts suitable for electrical control apparatus) |
| Power Requirements | 24 VDC nominal (typ. 18–30 VDC), ≤5 W typical in most deployments |
| Dimensions & Weight | Compact module footprint; commonly DIN-rail sized (approx. 120 × 100 × 25 mm), ~300 g typical |
| Operating Temperature | -20 to +60 °C typical cabinet rating (non-condensing) |
| Signal I/O Types | Typically used for serial/fieldbus interfacing or general-purpose I/O expansion depending on the host system |
| Communication Interfaces | Common variants include RS‑485/RS‑232; some builds may support Ethernet 10/100 (consult the specific revision) |
| Installation Method | DIN‑rail mounting or backplane slot (varies by system integration) |
Application Fields
- PLC/DCS panels in process plants where serial devices (meters, drives, analyzers) need stable integration
- Machine builders adding compact communication or I/O expansion in confined cabinets
- Utilities and water/wastewater sites standardizing on 24 VDC cabinet accessories
- Oil & gas skids, power gen auxiliaries, and OEM service spares for fast like‑for‑like replacement
Advantages & Value
- Reliability in the panel – Stable power behavior and isolation reduce nuisance faults in noisy environments.
- Compatibility-first approach – Form/fit/function alignment with ACC‑5595 series helps avoid expensive rewiring or requalification.
- Procurement simplicity – Standard 24 VDC and common field interfaces streamline stocking and interchangeability.
- Risk reduction – Pre‑shipment checks (power‑on and visual) and a 365‑day warranty keep maintenance risk low.
Installation & Maintenance
- Environment – Mount inside a ventilated control cabinet (typically DIN‑rail). Keep away from heat sources; allow at least 25 mm clearance for airflow.
- Wiring – Use shielded twisted pairs for serial lines; land shields to a single reference point. Verify torque on terminal screws and label conductors clearly.
- ESD & safety – De‑energize the panel before installation. Handle the board by edges and observe ESD precautions.
- Commissioning – Check power polarity, confirm LED status, then perform a loopback or device poll to validate communications.
- Routine care – Quarterly dust removal with dry air, check terminal tightness, and review event logs. Firmware/config updates apply only if your system revision supports them.
Supporting Components (Optional)
- ACC-DR35-CLIP – DIN‑rail mounting clip kit for secure, vibration‑resistant installation.
- CBL-RS485-2M – Shielded RS‑485 cable (2 m) with pre‑tinned leads for quick field termination.
- TB-20S – 20‑position pluggable terminal block for fast module swap‑outs during maintenance.
- SPD-485 – In‑line surge protector for RS‑485 lines in high‑EMI or outdoor conduit runs.
Quality & Certifications
- CE and RoHS compliance typically available for ACC‑5595 series modules
- UL recognition may depend on the specific OEM revision
- Manufactured under ISO 9001 quality systems (supplier dependent)
- Backed by a 365‑day warranty
One thing I appreciate is how quickly teams can get this module into service—most of the time it’s a straightforward replacement with predictable behavior. If you can share your host system and the exact revision you’re replacing, I can validate interface details and lock in the right unit for a first‑time‑right install.
