BIOPAC Systems MP35 4 Channel Data Acquisition System

BIOPAC MP35 is a four-channel data acquisition unit designed to capture and condition signals from up to four analog inputs, with one channel configurable as a trigger for synchronized recordings. The MP35 provides four analog input channels plus an MP35 I/O port offering eight TTL inputs and eight TTL outputs for simple signaling and control tasks, and it accepts signals from electrodes, transducers, and other sensors that BIOPAC’s hardware conditions before digitization. It connects to a computer via USB 2.0 full‑speed and is powered from a 12 V DC supply via a mains adapter suitable for 100–250 VAC, 50/60 Hz; the recommended power adapter is the AC300A (12 VDC at up to 1.25 A), with a 40 VA rating. The unit measures about 7 cm wide by 29 cm long by 25 cm high and weighs roughly 1.4 kg, and incorporates a 1.0 A fast-blow fuse for safety. Note: the MP35 is a discontinued product and BIOPAC now offers MP36 four‑channel systems for current use, while MP35 remains part of BIOPAC’s legacy hardware ecosystem.
