TOSHIBA SN321 TOSLINE-S20 Network Station Communications Module

In stock

The TOSHIBA SN321 is a high-density. It provides 64 channels of 24 VDC input with ≤1 ms ON / ≤1.5 ms OFF response, capturing fast sensor pulses, encoder Z-signals, E-Stop hard contacts, and high-speed switch transitions that standard DI cards miss.

🔷Product Overview

The SN321 is built for applications where milliseconds matter. With 64 inputs packed into a single slim card and 8-point common grouping, it delivers both high channel density and clean signal separation.

Each input group is optically isolated, so inverter noise, ground loops, and transient kickbacks from contactors or solenoids are contained. The 1 ms response window makes it suitable for:

High-speed part-presence detection
Encoder/Z-pulse and proximity-switch capture
E-Stop / trip-hardwire acquisition
SOE-adjacent event collection
Packaging, stamping, lithium-battery, and semiconductor indexing

It requires no external 24 V auxiliary for the module logic itself — the field side supplies the 24 V signal, while the card draws 5 V from the backplane.
