Siemens 6ES7155 Series Interface Module, 700mA

This Interface module is designed to mediate signals between control hardware and peripheral devices within industrial automation environments. It operates from a low-voltage supply and is intended for integration into PLC-based control systems where consistent current handling and electrical isolation are required. The unit is built to function reliably across a wide temperature range and conforms to contemporary environmental material restrictions.

• Operates from a 24V supply enabling standard PLC interfacing
• Handles 700 mA to support moderate current I/O loads
• Withstands a test voltage of 707 VDC for enhanced isolation
• Certified to RoHS reducing hazardous substance content
• Rated for use between -30 °C and +60 °C for broad ambient conditions

• Suitable for connecting discrete I/O modules in factory automation racks
• Ideal for signal interfacing in machine control panels
• Used for linking sensors and actuators to PLC I/O networks
• Can be used as a replacement for comparable Interface modules during maintenance

It has a proof test voltage of 707 VDC which demonstrates its capacity to endure high-voltage withstand checks used during verification of isolation integrity.

The module is specified to operate from -30 °C up to +60 °C, accommodating cold storage and warmed enclosure installations without derating.

It is specified to carry up to 700 mA, allowing it to drive moderate field devices or Interface circuitry without external amplifiers.

The product meets RoHS requirements, indicating restricted use of certain hazardous substances in its construction.
