Product Description
Key Features
- Digital output identity: SIMATIC S7-300 SM 322 digital output module with 16 DO and isolated solid-state relay outputs.
- Supply and output current: Load voltage: 24 V; 24 / 48 DC, with a permissible range of 20.4 V to 57.6 V. Output current for signal "1": 0.5 A rated value.
- Protection and diagnostics: Reverse polarity protection: Yes. Short-circuit protection: No; to be provided externally. Parameterizable diagnostic function and diagnostic alarm are available.
- Isolation and connection: Potential separation is provided between channels, between channels and backplane bus by Optocoupler, and between channels and the power supply of the electronics. Required front connector: 40-pin.
- Physical data: Dimensions: 40 mm width, 125 mm height, and 120 mm depth. Weight, approx.: 260 g.
- Lifecycle status: Product cancellation.
Applications
- Digital input control: The digital outputs can control a digital input.
- Redundant load control: Two outputs can be switched in parallel for redundant control of a load.
