Product Brief
ISOFACE™
Galvanically Isolated 8-Channel Digital Input IC
The ISO1I81xT digital input product family is a intelligent system solution offering robust galvanic isolation
between the µC on the “control side” and the 24V factory floor environment, frequently referred to as the
“process side”.
Industrial Control Applications:
„„ Programmable Logic Controllers (PLC)
„„ Distributed Control Systems
„„ Industrial PCs
„„ General Control Equipment
„„ Sensor Input Modules
Benefits of the integrated galvanic isolation of the IS01I81xT digital input product family:
„„ Temperature range up to +135°C tjunction
¢ Ideal for highly compact industrial applications
„„ Low temperature drift
¢ Robust over operational life-time
„„ Superior EMI robustness
¢ Secure data transfer under very harsh conditions
