RIGOL MC3132 32-Channel Multiplexer Module

Rigol MC3132 32-Channel Multiplexer Module is designed for high-density, high-accuracy signal routing in laboratory automated test systems, suitable for integration with the Rigol M300 series mainframe. The MC3132 supports both 2-wire and 4-wire configurations, facilitating temperature measurement, resistance, voltage, and other electrical parameter testing across multiple channels.

This module features 32 switchable channels, each capable of routing HI and LO inputs, with scanning speeds reaching 60 channels per second and open/close switching up to 200 channels per second. With a maximum input voltage of 300 Vrms, maximum current of 1 Arms, and a power limit of 50 VA per channel, the MC3132 is robust for demanding lab measurement scenarios, while maintaining low initial closed channel resistance (less than 1 Ω) and high isolation (>10 GΩ).

• Features 32 independent channels for versatile signal routing.
• Supports both 2-wire and 4-wire measurement modes for flexible configuration.
• Delivers high isolation (>10 GΩ) and minimal offset voltage of 5 μV.
• Maximum input voltage of 300 Vrms and current up to 1 Arms.
• Rapid scanning (60 Ch/s) and switching (200 Ch/s) capabilities.
• Low initial closed channel resistance (less than 1 Ω) for high accuracy.
• Compatible with MC3065 mainframe for true multi-channel expansion.
• Bandwidth up to 1 MHz for fast and precise signal acquisition.
• Cold junction accuracy of 0.8℃ typical, suitable for temperature measurement.
• Compatible terminal blocks: M3TB32 and M3TB32T.

Typical use cases include laboratory measurement and automation, industrial test benches, and high-channel-count data acquisition. The MC3132 is especially suitable for temperature sensor multiplexing, resistance and voltage scanning, and general automated electrical test requirements.
