YOKOGAWA ER5*B — Multi-Channel RTD Input Module | CENTUM VP / CS 3000 DCS Platform
Engineering Background
The ER5*B is a field-proven resistance temperature detector (RTD) input module designed for Yokogawa’s CENTUM VP and CS 3000 distributed control systems. Deployed across petrochemical, power generation, and pharmaceutical process plants worldwide, it delivers high-accuracy temperature measurement with channel-to-channel isolation and universal RTD range compatibility — critical requirements for safety-instrumented and continuous-process environments.
Product Positioning
For procurement engineers sourcing DCS I/O cards, the ER5*B represents a direct OEM replacement or capacity-expansion module for existing CENTUM VP / CS 3000 architectures. Konmask supplies both new-surplus and factory-refurbished units with full traceability documentation, enabling fast MRO turnaround without extended lead times from the OEM channel.

Proven Application Environments
- Petrochemical & Refining: Reactor temperature monitoring, distillation column profiling, heat-exchanger control loops
- Power Generation: Turbine bearing temperature, boiler drum temperature, steam-line monitoring
- Pharmaceutical / Life Sciences: Autoclave and bioreactor temperature validation (21 CFR Part 11 compatible DCS environments)
- Pulp & Paper: Digester and dryer section temperature control
- Water & Wastewater: Process temperature monitoring in SCADA-integrated CENTUM VP installations
- Food & Beverage: CIP/SIP temperature verification loops
Engineering Advantages
- Universal RTD Compatibility: Supports Pt100, JPt100, Cu10, Ni100, and Ni120 — eliminates the need for separate module SKUs per sensor type
- Channel-to-Channel Isolation: Prevents ground-loop interference in multi-point temperature networks, reducing measurement noise in electrically noisy plant environments
- Hot-Swap Design: Modules can be inserted and removed under power without shutting down the I/O nest, minimising process downtime during maintenance
- High-Density I/O: 16 channels per slot maximises cabinet space utilisation in brownfield expansions
- Seamless CENTUM VP Integration: Auto-recognised by the CENTUM VP engineering environment (CAMS for HIS); no manual address configuration required
- Low Drift: Precision ADC with on-board cold-junction compensation ensures long-term measurement stability between calibration intervals
System Architecture & Signal Flow
The ER5*B resides in a standard CENTUM VP I/O nest and communicates with the Field Control Station (FCS) via the V-net/IP or ESB bus, depending on the FCS generation. Each RTD sensor connects to the module’s terminal block using 3-wire or 4-wire configurations. The module performs on-board A/D conversion and transmits engineering-unit values directly to the FCS tag database, where they are available to control function blocks (PID, ratio, cascade) without additional signal conditioning hardware.
Signal path: RTD Sensor → Field Terminal Block → ER5*B A/D Converter → ESB/V-net Bus → FCS Tag Database → HMI / Historian
Sourcing & Quality Verification
- All units are inspected upon receipt against YOKOGAWA part-number markings and firmware revision labels

- Refurbished units include a Konmask inspection certificate with technician sign-off and test date
- Traceability documentation (test report, photos) available upon request for regulated-industry procurement
- RoHS compliance status confirmed per YOKOGAWA product declaration
Procurement Process
- Step 1 — Confirm Compatibility: Verify your FCS generation (CENTUM VP R5.x / R6.x or CS 3000) and I/O nest model before ordering. Contact our engineering team if unsure.
- Step 2 — Request a Quote: For volume orders (>3 units) or urgent MRO requirements, email [email protected] for lead time and pricing confirmation.
- Step 3 — Place Order: Add to cart and complete checkout. We accept T/T bank transfer, PayPal, and major credit cards.
- Step 4 — Shipment: Orders ship within 1–3 business days from Xiamen, China. DHL Express, FedEx, and sea-freight options available. Export documentation (commercial invoice, packing list, CO) included.
- Step 5 — After-Sales Support: 90-day warranty on all units. Technical support available via email and WhatsApp (+0086 19859288691).
Technical FAQ
- Q: Is the ER5*B compatible with CENTUM VP R6.x?
- A: Yes. The ER5*B is backward-compatible across CENTUM VP R4.x through R6.x and CS 3000 R3.x. Confirm your I/O nest model (ANB10D / ANB11D) for physical slot compatibility.
- Q: Can I mix Pt100 and JPt100 sensors on the same module?
- A: RTD type is configured per-channel in the CENTUM VP engineering environment, so yes — different RTD types can be assigned to individual channels on the same ER5*B module.
- Q: What is the difference between ER5*B and ER5*A?
- A: The ER5*B is the current production revision with enhanced EMC performance and extended RTD type support. The ER5*A is an earlier revision; both are physically interchangeable in the same I/O nest slot.
- Q: Do you provide calibration certificates?
- A: Konmask provides functional test reports. NIST-traceable calibration certificates can be arranged through a third-party calibration lab upon request (additional lead time and cost apply).
- Q: What is the minimum order quantity?
- A: MOQ is 1 unit. Volume pricing is available for orders of 3 units or more.
- Q: Can you supply the matching terminal block / field terminal assembly?
- A: Yes. Please contact us with your I/O nest model and we will confirm the compatible field terminal assembly (FTA) part number.
