• For connection of solenoid valves, DC contactors and<br />

signaling lamps<br />

• With integrated safety func tions for failsafe operation<br />

• Can be used in failsafe mode<br />

- Centrally: with S7-31xF-2 DP<br />

- Distributed in ET 200M: with SIMATIC S7-31xF-2DP,<br />

S7-416F-2 and S7-400F/FH<br />

• Suitable for use in standard operation in the same way as<br />

S7-<strong>300</strong> modules<br />

This module is designed for<br />

• an ambient range of – 25 °C to + 70 °C, condensation<br />

permissible.<br />

• extraordinary medial load (for example by chloric and sulphuric<br />

atmospheres).<br />
