The Hioki U8556 5-Channel Direct Connection Current Module is a current measurement module which features lightning-fast sampling. Up to five channels can be simultaneously measured at a sampling rate of up to one millisecond when five sensors (not included) are connected to a single unit. Due to this fast sampling rate, even momentary changes in current can be captured.

This direct connection module cannot perform measurements by itself and is designed for use with the Hioki LR8450 or LR8450-01 Memory HiLogger (not included).
