The Yamatake SDC20 (often branded under the Azbil Group) is a reliable, compact digital indicating controller designed for precise process control in industrial environments. Whether you are a system designer or a maintenance engineer, the SDC20/21 User Manual (CP-UM-1470E) is your primary resource for installation and troubleshooting. 1. Key Technical Specifications

The SDC20 series is built to handle standard industrial power supplies and varied environmental conditions:

Power Supply: 100 to 240 V AC (operating range: 85 to 264 V AC). Frequency: 50/60 Hz. Ambient Temperature: 0 to 50°C during operation. Humidity: 10% to 90% RH (non-condensing). Accuracy: ±0.5% FS.

Compact Design: Depth of 60mm with a slim 2mm front panel mask. 2. Installation and Safety Guidelines

Proper installation is critical for both device longevity and personnel safety.

Panel Mounting: The unit must be mounted into a control panel to prevent accidental contact with the rear terminals.

Safety First: Always turn the main power OFF before connecting or disconnecting any wiring to avoid electric shock.

Grounding: Ensure the controller is connected to an earth ground according to local standards.

Environment: Do not operate the SDC20 in the presence of flammable vapors or liquids, as this poses a significant explosion risk. 3. Operational Features

The SDC20 supports multiple control modes and input types to fit various process needs:

Input Types: Supports multi-range inputs including thermocouples, RTDs, and linear DC voltage/current. yamatake sdc20 user manual

Control Methods: Options include standard PID control, ON/OFF control, and advanced "RationaLOOP PID (Ra-PID)" combined with self-tuning for minimized overshoot.

Event Outputs: Can be configured for heat/cool control using a combination of control and event output points.

Interface: Features a console with a PARA key, ENT key, and a Loader connector for easy parameter adjustment. 4. Wiring and Communication

For integrated systems, the SDC20 offers robust communication options:

Serial Communication: RS-485 or RS-232C interfaces are available for connecting to PLCs or other external devices.

Shielding: When using long communication cables (up to 15m for RS-232C), always connect the shield line to the FG (frame ground) terminal to minimize signal noise.

Protection: Using a surge protector (like Yamatake's "SurgeNon") is recommended if the unit is installed in areas prone to lightning strikes. SDC20/21 User Manual Overview | PDF | Power Supply - Scribd
