Siemens SIMATIC S7-200 SMART Digital Output Expansion Module

Detailed Description:

• Relay Output: All 8 channels on the module are relay contact outputs (normally open contacts), each capable of independent switching. The relay contacts allow direct control of both alternating current (AC) and direct current (DC) loads, offering great flexibility in load types.

• Load Capacity: Each relay contact is rated for 2.0 A @ 250 V AC or 30 V DC, enabling direct driving of common industrial actuators without the need for additional intermediate relays.

• Electrical Isolation: There is complete electrical isolation between the relay coil side (controlled by the PLC) and the contact side (connected to the field load). This provides excellent noise immunity and safety protection for the PLC system.

• Compact and Plug-and-Play: The module is compact and connects directly to the right side of an S7-200 SMART CPU or the existing expansion module via a standard flat cable, ensuring easy installation. The system automatically recognizes the module and assigns I/O addresses.

• Status Indication: Each output channel has an independent green LED indicator, clearly showing the output status (ON/OFF) of that point, facilitating on-site commissioning and troubleshooting.

• Typical Applications: Widely used in small automated machines, machine control panels, packaging machines, conveyor lines, and other applications requiring control of loads at various voltage levels.
