Digital I/O module IP-PN-8IA

ProfiNetIO-LinkEthernet

Product Description The IP-PN-8IA is a PROFINET RT slave and IO‑Link master module for industrial automation. It provides 8 M12 A‑code Class A IO‑Link master ports and supports configurable Pin 2 and Pin 4 functions per port, enabling up to 16 configurable digital input/output channels. The module implements PROFINET IO Device protocol with a minimum real‑time cycle of 1 ms and supports IO‑Link V1.1 master protocol. Designed for field use, the unit features an IP67 housing, integrated diagnostics and temperature monitoring, automatic protection mechanisms and online firmware upgrade without disassembly.

Key Benefits

• Simplify industrial networking by combining PROFINET communication and IO‑Link master functionality in a single compact module.
• Improve system flexibility through configurable DI/DO channels (Pin2/Pin4) per port to adapt to varied sensor and actuator requirements.
• Enhance operational reliability with integrated diagnostics and temperature protection to reduce unplanned downtime.
• Reduce maintenance effort thanks to a non‑potting design and online firmware upgrade capability.
