Description
The Siemens SIMATIC S7-300 SM 322; DO 32xDC 24 V/0.5 A provides 32 digital transistor outputs for controlling 24 V DC loads in industrial automation applications. The outputs are electrically isolated from the backplane bus and from each other in four groups of eight, providing greater flexibility when connecting field devices. Each output can handle up to 0.5 A, while the total current per output group is limited to 4 A at up to 40°C and 3 A at up to 60°C for horizontal installation. The module supports control of digital inputs and includes inductive shutdown-voltage limitation to L+ (−53 V) to help protect the output circuitry when switching inductive loads.
The module is intended for applications that require a high number of discrete output signals from an S7-300 controller. It supports shielded field cables up to 1,000 m and unshielded cables up to 600 m, with a switching frequency of up to 100 Hz for resistive loads and 0.5 Hz for inductive loads. Siemens specifies 500 V DC isolation testing, a 40-pin front connector, and individual green output-status indication for the channels. The SM 322 provides a compact high-density output solution for machine automation, actuator control, conveyor systems, production equipment, and other S7-300-based industrial control applications.
