ESM-103B
Product Name
TERASAKI ESM-103B Industrial Control Board (Multi-Functional Automation Control & Signal Processing Dedicated)
(Naming convention explanation for TERASAKI control modules:
- “ESM”: Product family identifier, representing “Embedded System Module” — specialized in embedded control with integrated I/O and communication capabilities, distinguishing it from basic I/O expansion cards.
- “103”: Model sequence code: “103” denotes the 3rd generation of the ESM series, optimized for higher processing speed and expanded protocol support compared to predecessors like ESM-102.
- “B”: Hardware revision code: “B” indicates enhanced environmental resistance (conformal coating + reinforced terminals) and compatibility with TERASAKI’s latest T-Connect 3.0 system, vs. “A” for legacy system compatibility.
- Core positioning: Serves as the “control & signal hub” in industrial automation systems (e.g., smart manufacturing lines, building energy management, and process control stations) — bridging field devices, controllers, and HMI platforms to enable closed-loop automation .)
2. Product Description
The ESM-103B is a modular industrial control board engineered by TERASAKI to address integrated automation challenges (e.g., synchronized sensor data processing in assembly lines, multi-device coordination in smart factories). It delivers core value through five key advantages validated by industrial applications :
2.1 Versatile Multi-Signal Handling
Integrates universal I/O interfaces supporting diverse signal types:
- Analog signals: 4-20mA current loops, 0-10V voltage signals (compatible with temperature/pressure transmitters).
- Digital signals: Dry/wet contacts (for limit switches, alarms) and pulse signals (for flow meters, encoders).
This eliminates the need for dedicated signal converters, reducing system complexity by 30% in mixed-signal environments.
2.2 High-Speed Real-Time Processing
Equipped with a 32-bit RISC processor and optimized control algorithms, it achieves:
- Data processing latency: ≤1ms (critical for time-sensitive tasks like emergency shutdowns).
- Support for advanced control logic: PID regulation, sequential logic, and counter/timer functions — enabling precision control of processes (e.g., temperature stability ±0.5°C in heating systems).
2.3 Industrial-Grade Communication Compatibility
Native support for mainstream automation protocols:
- Fieldbuses: Modbus RTU/TCP, Profibus DP.
- Industrial Ethernet: EtherNet/IP.
This ensures seamless integration with PLCs (e.g., Siemens S7-1200), HMI panels, and cloud platforms — enabling real-time data sharing across the entire automation hierarchy .
2.4 Flexible Modular Expansion
Adopts a plug-and-play modular design:
- Supports daisy-chaining of up to 8 ESM-103B boards for scalable I/O capacity (from 16 to 128 channels).
- Compatible with TERASAKI’s ESM series expansion modules (e.g., ESM-201A analog output card) — adapting to evolving system requirements without hardware overhauls.
2.5 Rugged Reliability for Harsh Environments
Constructed to withstand industrial stressors:
- Component grade: High-temperature capacitors (125°C rating) and gold-plated terminals for corrosion resistance.
- Protection mechanisms: Overcurrent, overvoltage, and overtemperature safeguards — preventing damage from power surges or sensor short circuits.
