Product Brief - ISOFACE™ ISO2H823V Digital Output Switch with 10-fold Diagnostics

Product Brief
ISOFACE™
Galvanic Isolated 8-Channel High-Side Switch with 10-fold Diagnostics
The ISO2H823V establishes a new standard in diagnostics for industrial control applications.
For example, in industrial plants with capital intensive single-tool equipment at work or with time
critical chemical processes running, obtaining in real-time differentiated feedback from the factory
floor enables both, preventive maintenance and drastic reduction of the time to fix a problem.
This is why the ISO2H823V is a highly desirable system solution. System designers benefit from the
ISO2H823V through short time to market, reduced PCB area and uncompromised product reliability.
Application Examples
„„ Programmable Logic Controllers (PLCs)
„„ Distributed Control Systems
„„ Robotics
„„ General Control Equipment
The ISO2H823V integrates
„„ Robust 2.5kV galvanic isolation
–– UL508 and CSA C22.2 No. 14 certified
–– To protect the 3.3V control domain of an industrial control system
from the harsh 24V process side
–– Exceeding the IEC 61131-2 requirements for reinforced isolation
„„ 8-channel high-side power-switching capabilities
–– Of up to 0.6A per channel
–– With active current limitation and overtemperature protection
„„ 10-fold diagnostic feedback
–– 5 types of feedback which are available individually for each of the eight outputs
–– 5 types of IC-level feedback
The ISO2H823V enables product designs which meet the stringent EMI requirements of the
IEC 61131-2 norm (zone C) applicable for Programmable Logical Controllers (PLC).
