The 85M-1602-T module from the ioPAC 8500/8600 series is a high-performance digital input module with 16 channels, specifically designed for rugged industrial environments. Supporting both sink and source input modes at 24 VDC, it operates reliably across a wide temperature range from -40 to 75°C. With 3 kVDC isolation protection, it ensures safe and stable operation by shielding the control system from surges and electrical noise. Its flexible I/O functionality supports digital input, event counter, or frequency mode for varied applications.

The module accepts both dry and wet contact inputs (NPN or PNP), making it highly adaptable for status monitoring, event logging, and counting operations. With compact dimensions, spring-type Euroblock connectors, and low power consumption, the 85M-1602-T is ideal for space-constrained and energy-efficient automation setups.
