| Terminal | Function | | :--- | :--- | | 1, 2 | Power supply (AC or DC) | | 3, 4, 5 | Sensor input (thermocouple/RTD/DC) | | 6, 7 | Control output (relay/voltage/current) | | 8, 9 | Alarm output (optional) | | 10, 11, 12 | RS‑485 communication (＋, －, SG) |

Proper mechanical and electrical installation prevents device failure and reduces electrical noise interference. Panel Mounting Steps

Configure alarm types (e.g., High Limit, Low Limit, Deviation) to protect equipment.

Supports relay contact, voltage pulse (for SSR drive), and current outputs. 2. Hardware Specifications yamatake sdc20 user manual

You can access official and archived versions of the documentation here:

The SDC20 categorizes parameters into distinct operational layers to prevent accidental alterations during production cycles. Mode 1: Operation Mode Accessed directly upon power-up.

Generally, these units operate on a wide range of voltages (e.g., 100-240VAC or 24VDC), detailed on the side label of the device.

: Designed for indoor use at temperatures between 0 to 50 °C and humidity levels of 10 to 90 %RH. Key Operations & Setup
