Product Introduction
Remote node units are critical when field I/O is distributed far from the main control cabinet. The is a YOKOGAWA CENTUM CS 3000 / CENTUM VP dual-redundant ER bus remote node unit. The series indicates a dual-redundant remote node, while the full model suffix (e.g., -415, -426, -445) determines the power supply voltage, temperature rating, and explosion protection configuration.
For maintenance and procurement teams, this unit is typically sourced as an OEM replacement for failed or aging remote nodes in CENTUM CS 3000 / CENTUM VP FCS environments. It mounts in a standard 19-inch rack and houses power supply modules (PW481/PW482/PW484) and an ER bus slave interface module (EB501), providing the interface between the FCU and field I/O modules at remote locations. Because the ANR10D has multiple suffix variants, the exact power voltage and configuration must be confirmed against the physical label before ordering.

Suffix reference (based on available documentation): 4 = dual-redundant power; 1/2/4 = 100–120 V AC / 220–240 V AC / 24 V DC; 5/6 = basic / ISA G3 wide-temp; E/F = explosion-proof variants.
Key Selling Points & Differentiators
- Dual-redundant ER bus: Supports redundant communication with the FCU for high availability at remote locations.
- Dual-redundant power supply: Reduces single-point power failure risk at the remote node level.
- 19-inch rack mount: Standard industrial mounting for easy integration into remote I/O cabinets.
- OEM YOKOGAWA remote node: Suitable for CENTUM CS 3000 / CENTUM VP maintenance, replacement, or spare stocking.
- Multiple suffix options: Available in AC and DC power variants, with basic and wide-temperature configurations.
- Not recommended for: Local ESB bus node applications (use ANB10D), single-redundant bus requirements (use ANR10S), or systems without ER bus coupler modules. Always confirm the full suffix before ordering.
Quality Transparency SOP
Remote node units should be verified for both mechanical integrity and bus/power module compatibility.
- Incoming visual QA: Inspect factory sealing, label integrity, rack mounting points, and module slot condition.
- Label verification: Confirm full model (e.g., -415, -426) and suffix match the required configuration.
- Module slot inspection: Check power module and EB501 module slots for bent pins, oxidation, or mechanical damage.
- Power module check: Confirm installed power modules (PW481/PW482/PW484) match the existing node voltage configuration.
- ER interface check: Verify EB501 module presence and connector integrity for dual-redundant ER bus connection.
- Final packing: Record serial/lot information, apply protective packaging, and seal with a condition label.
Technical Risk Avoidance
Confirm the full suffix code. ANR10D has multiple variants (e.g., -415, -426, -445) that differ in power voltage and temperature/explosion ratings. Always match the full model against the existing unit label.
Do not confuse with local nodes. ANR10D is a remote node unit connected via ER bus. Local ESB bus node applications require ANB10D series units.
Verify power voltage compatibility. The suffix determines whether the unit uses 100–120 V AC, 220–240 V AC, or 24 V DC. Installing the wrong voltage can damage the unit.
Check ER bus coupler requirement. The FCU must have an ER bus coupler module to connect to ANR10D remote nodes.
Respect the per-FCU remote node limit. A single FCU supports up to 8 remote nodes via ER bus.
Confirm EB501 module presence. The ER bus slave interface module (EB501) must be installed for communication with the FCU.
Buyer’s FAQ
Is this unit genuine YOKOGAWA?
Yes. The is an OEM YOKOGAWA CENTUM CS 3000 / CENTUM VP ER bus remote node unit. We supply it as new original/new surplus unless otherwise stated.
What does ANR10D do?
It is a dual-redundant ER bus remote node unit that houses power supply modules and an EB501 ER bus slave interface module, providing remote I/O expansion for CENTUM CS 3000 / CENTUM VP FCS.
What is the difference between ANR10D and ANB10D?
ANR10D is a remote node connected via ER bus for distributed I/O locations. ANB10D is a local node connected via ESB bus within the same cabinet as the FCU.
What power voltages are available?
Depending on the suffix: 100–120 V AC (-41x), 220–240 V AC (-42x), or 24 V DC (-44x).
Can I substitute -415 with -426?
Not automatically. The power voltage differs (100–120 V AC vs. 220–240 V AC). Always confirm the full suffix matches the existing installation.
What is the warranty and lead time?
Each unit carries a standard 12-month functional warranty from shipment, excluding damage from incorrect installation, voltage mismatch, or bus configuration errors. In-stock units typically ship within 1–3 business days after payment confirmation.
