Siemens 6ES7155 Series Interface Module, 700mA

This Interface module provides a Compact connection point for control and signalling circuits in industrial automation. It operates on low-voltage systems and is intended for integration into PLC-based setups where stable current delivery and predictable thermal performance are required. The unit is manufactured to fit standard mounting arrangements and complies with common environmental handling requirements for electronic assemblies.

• 24V supply capability supporting common control voltages and compatibility
• 700mA rated current to maintain steady peripheral power delivery
• Operable down to -30°C for low-temperature installations
• Horizontal use allowed up to +60°C for constrained ventilation areas
• 700mA DIN-rail compatibility simplifies retrofit and panel installations

• Suitable for signalling interfaces in factory automation racks
• Ideal for auxiliary power feeding of sensors and small actuators
• Used with PLC cabinets requiring space-efficient modules
• Can be used for maintenance spares in industrial control rooms

The unit is designed with a slim profile measuring 50mm in width and 138mm in length to suit narrow module slots and optimise panel real estate.

When installed horizontally it can withstand ambient temperatures up to +60°C, which supports use in warmer cabinet zones with limited airflow.

The device requires a 24V supply and will deliver up to 700 mA to connected circuits under specified conditions.

In vertical orientation the maximum recommended ambient temperature is +50°C to maintain thermal margins.
