Description
1. At-A-Glance Executive Brief
- Model: SR1030B62
- Brand: Yokogawa
- Part Type: Digital Indicating Controller / Process Control Module
- Lifecycle Status: Mature / Legacy Support Tier
- Weight: 0.25 kg
- Core Protocol: Standard Analog / Discrete Loop Control
2. Technical Introduction
Process loops driven by legacy indicating controllers often suffer from drift, display fading, or internal component degradation that threatens overall loop stability. Sourcing reliable replacement hardware becomes difficult when dealing with obsolete inventory channels that lack traceability and performance testing. The Yokogawa SR1030B62 drops directly into existing panel cutouts and terminal arrangements, providing precise microprocessor-based PID control and clear process variable visualization without requiring expensive panel modifications or control philosophy redesigns.
3. Core Technical Specifications

- Control Algorithm: PID with auto-tuning
- Display Type: Digital LED/LCD Process Value (PV) and Setpoint (SV)
- Control Output: Analog / Relay configuration per suffix specification
- Mounting Type: Panel Mount / DIN Sized
- Operating Temperature Range: 0°C to +50°C
- Power Supply Requirements: Standard Industrial Control Voltages
- Unit Weight: 0.25 kg
4. Field Engineer’s Tech Notes
- Terminal Mapping & Scaling: Double-check raw signal scaling and input range configuration parameters prior to loop energization. An uncalibrated universal input type setting will instantly skew the PV transmission to the main control system.
- Panel Grounding: Ensure the controller chassis ground terminal ties directly to the cabinet ground bus. High electromagnetic interference (EMI) from nearby variable frequency drives can induce jitter on unshielded analog input loops if grounding is bypassed.
5. Adaptive QA & Testing Protocol
Testing involves bench-powering the unit and applying precision current and resistance signals across the universal input channels to verify analog-to-digital conversion accuracy. Engineers simulate step-changes to validate PID response timing, relay actuation thresholds, and front-panel display legibility under load. Calibration certificates and verification logs are available upon request to establish complete operational pedigree prior to plant installation.
6. Buyer’s FAQ
- What warranty terms apply to this replacement controller?All units include a standard 12-month replacement warranty from the invoice date.
- Are these units shipped with factory configuration profiles loaded?Units ship in standard factory default states; technicians must configure control parameters and scaling to match specific loop requirements.
- Is this hardware verified original OEM surplus?Yes, every module is verified genuine Yokogawa stock with full physical and electrical traceability.
- What is the typical shipping lead time for urgent requirements?In-stock items ship the same business day via priority air couriers to minimize unexpected plant downtime.
