Connect industrial buses with dual-channel bi-directional optocoupler
The ACSL-7210 is a bi-directional 25 MBd digital optocoupler optimised for bi-directional industrial communication networks using high speed protocols such as PROFIBUS fieldbus and Serial Peripheral Interface (SPI). The ACSL-7210 utilises Avago’s proprietary IC and patented packaging technologies to achieve 3,750 VRMS signal isolation in a low profile SO-8 package while supporting high speed full-duplex data communications with data rates up to 25 Mbd. It supports full duplex communications, data rates down to DC, has a profile of under 2 mm, and has CMOS-level inputs and outputs. Maximum pulse width distortion is 10 nsec and maximum propagation delay is 40 nsec; minimum common-mode rejection is 20kV/μsec at 1 kV VCM. It is IEC/EN/DIN EN 60747-5-5-compliant with VIORM = 567 VPEAK and reinforced insulation. Use it for industrial buses and in particular, Profibus, in noisy industrial environments.
