TE Connectivity Entrelec 1SNA031802R1700 BNMS-T24VAC-1 is a compact 24 V AC input optocoupler plug with 2.5 kV galvanic isolation and a maximum 58 V DC / 30 mA output for industrial automation and control signal interfacing.
The TE Connectivity Entrelec BNMS-T24VAC-1, part number 1SNA031802R1700, is a compact 24 V AC input optocoupler plug designed for signal isolation and interfacing in industrial automation and control systems. Part of the Entrelec Interfast MS range, it provides galvanic separation between control inputs and downstream electronic circuits, helping protect sensitive equipment from electrical disturbances.
Designed for a nominal 24 V AC input, the BNMS-T24VAC-1 operates across an input voltage range of 20.4–26.4 V AC with a maximum input current of 8.5 mA. The optocoupler provides an output capability of up to 58 V DC / 30 mA and an input-to-output isolation voltage of 2.5 kV, making it suitable for reliable signal transmission within PLC and industrial control installations.
The module measures only 34.5 × 5 × 38 mm and weighs approximately 0.004 kg, allowing it to be incorporated into densely populated control assemblies. A typical triggering threshold of 13 V AC and switching times of approximately 6 ms / 10 ms provide dependable operation for industrial input signal conditioning and isolation.
Optocouplers transfer electrical signals while maintaining galvanic isolation between their input and output circuits. The TE Connectivity Entrelec BNMS-T24VAC-1 provides 2.5 kV isolation, allowing a 24 V AC control signal to be interfaced with downstream control electronics while reducing the direct electrical connection between the two circuits.
Its compact Interfast MS plug format makes the 1SNA031802R1700 particularly useful for PLC interfaces, machine controls and industrial automation systems where panel space is limited. The defined switching characteristics, wide industrial temperature range and low input current support dependable signal conditioning in demanding control cabinet applications.
