Siemens 6ES7326-1BK02-0AB0 Digital I/O Module

The Siemens 6ES7326-1BK02-0AB0 digital input module provides 24 digital input channels for SIMATIC S7-300 PLC systems, enabling reliable sensing from sensors and automation equipment. It operates with 24 V DC inputs that are sink/source compatible, with galvanic isolation between channels and groups and a configurable input delay typically 0.1–20 ms. The module draws approximately 80–120 mA of local current and about 60 mA from the backplane, includes per-channel status LEDs, and mounts on a DIN rail within an S7-300 rack with IP20 protection. Its compact footprint is about 125 × 40 × 120 mm, weighs roughly 0.25 kg, and is commonly used in manufacturing plants, automated production lines, and robotics systems for high-speed digital input signal acquisition and sequencing.
