Hioki SW1002 Switch Mainframe

The SW1002 is a high-capacity switch mainframe built to streamline battery cell and module testing across many channels. It accommodates multiplexer modules (such as SW9001 or SW9002) which expand channel connectivity. The system lets a user connect two separate measurement instruments and switch between them dynamically to carry out open-circuit voltage (OCV), internal resistance, or external potential measurements on battery cells or modules. The internal circuitry is engineered to minimize measurement error between channels, making it suitable for precision impedance work. It supports modules up to 60 V DC, and its switching infrastructure includes features like channel scanning, communication command forwarding (so the PC can control measurement instruments through the mainframe), and built-in protection for each channel. The SW1002 is intended for laboratory or production environments where high-channel, reliable battery testing is required.

Features

• Houses multiplexer modules (e.g. SW9001 / SW9002) to expand channel capacity.
• Supports up to 264 channels (2-wire mode) or 72 channels (4-terminal pair mode) in full configuration.
• Can switch between two measurement instruments (e.g. voltmeter + battery tester) during testing.
• Precision design to minimize inter-channel error in impedance measurements (approx. 0.01 % full scale effect).
• Supports battery module testing up to 60 V DC.
• Built-in short-circuit protection fuses on each channel for safety.
• Scan function and channel-list switching support (automated channel sequencing).
• Communication interfaces: LAN, USB, RS-232C, and command forwarding for measurement instruments.
• Accepts signals up to 60 V DC, 30 V AC (RMS) on input.
• Rugged rack-style form factor (~430 mm × 132 mm × 420 mm) and weight around 6.0 kg.
