2N3A3620-B
2N3A3620-B Industrial-Grade Discrete Input/Output (I/O) Module (Dedicated for High-Density Discrete Signal Handling, Compatible with Industrial PLC/Scanner Systems like SST-PFB-CLX)
Product Description
The 2N3A3620-B is a rugged, high-density discrete I/O module engineered to collect and transmit discrete signals (on/off, status, trigger) between field devices and centralized control systems—critical for industrial automation scenarios such as manufacturing assembly lines, material handling, and process equipment monitoring. As a key field-level component, it works in tandem with scanner modules like the SST-PFB-CLX to form a “discrete signal acquisition → standardized transmission → control execution” loop:
Field devices (e.g., limit switches, proximity sensors, pushbuttons) send discrete input signals to the 2N3A3620-B, which filters and isolates these signals to eliminate electromagnetic interference (EMI) from industrial environments. The module then transmits the validated signals to the SST-PFB-CLX via compatible industrial protocols (e.g., PROFIBUS DP), enabling the scanner to relay data to upstream PLCs (e.g., Allen-Bradley ControlLogix) for real-time decision-making. When receiving control commands from the PLC (via the SST-PFB-CLX), the 2N3A3620-B drives discrete actuators (e.g., solenoid valves, indicator lights, contactors) via its output channels—with built-in protection to prevent damage from short circuits or overloads.
Its compact, industrial-grade design ensures stable operation in harsh conditions (wide temperature ranges, vibration, humidity), while hot-swap capability minimizes downtime during maintenance. It is ideal for applications requiring high I/O density and reliable discrete signal management, such as automotive manufacturing or packaging machinery.
