TE Connectivity BNMS-P48VDC-3 1SNA031811R0700 is a compact 48 V DC transistor output optocoupler plug with a 100 mA output and 2.5 kV input/output isolation for industrial automation and control signal interfacing.
The TE Connectivity BNMS-P48VDC-3, part number 1SNA031811R0700, is a compact 48 V DC transistor output optocoupler plug designed for industrial control and automation signal interfacing. Part of the established Entrelec Interfast MS range, it provides galvanic isolation between input and output circuits while allowing electronic control signals to be transferred without a mechanical switching contact.
Designed for a nominal 48 V DC input, the BNMS-P48VDC-3 operates across an input voltage range of 40.8–57.6 V DC and has a maximum input current of 3.9 mA. Its semiconductor output is rated up to 58 V DC / 100 mA, making it suitable for interfacing compatible PLC, controller and industrial electronic circuits.
The optocoupler provides 2.5 kV input/output isolation and fast semiconductor switching, with specified switching times of 20 µs / 1.3 ms. Measuring only 5 mm wide, the plug is particularly useful where reliable signal isolation is required without consuming unnecessary control-panel space.
Optocouplers transfer electrical control signals while maintaining galvanic separation between their input and output circuits. This isolation can help protect sensitive PLC and controller electronics from electrical potential differences and unwanted interaction between control circuits while providing fast, contactless semiconductor switching.
The TE Connectivity BNMS-P48VDC-3 combines a 48 V DC input, 100 mA transistor output and 2.5 kV isolation in a compact plug format. It is therefore particularly suitable for industrial automation systems requiring reliable electronic isolation and switching between control signals and compatible output circuits.
