Product Description
Key Features
- Exact module identity: SIMATIC S7-300 SM 322 digital output module with 8 isolated relay outputs.
- Relay output capacity: 8 relay outputs; output current for signal "1": 5 A rated value and 5 mA minimum load current.
- Supply and coil voltage: Load voltage: 120 V rated value (DC) and 230 V rated value (AC); relay coil L+ rated supply voltage: 24 V DC.
- Connection and isolation: Required front connector: 40-pin; digital outputs are potential-separated between channels and from the backplane bus by optocoupler.
- Installation limits: Maximum output current is 5 A for horizontal installation up to 60 °C and vertical installation up to 40 °C.
- Lifecycle: Product cancellation.
