Switching Box

Switching Box ISW-50G

This is a switching box with a built-in A/D converter (ADC) developed to expand the number of measuring channels combined with a data logger TDS-540, TDS-630, or TDS-530.
Combined use with a data logger TDS-540 and 20 switching boxes ISW-50G allows high-speed scanning of 1000 channels in 3 seconds.
