TE Connectivity 1SNA020265R0400 EM16D is a 16-way industrial diode module with sixteen pass-through diodes and screw-clamp connections for control, automation and interface circuits.
£119.65
The TE Connectivity EM16D, manufacturer part number 1SNA020265R0400, is an industrial 16-way diode module from the Entrelec Interfast Series 20.000 electronic interface range. Designed for control-panel and automation applications, it integrates sixteen pass-through diodes into a single rail-mounted module, providing a convenient alternative to installing and wiring multiple discrete diodes.
The EM16D uses 16 individual pass-through diode channels and has a module spacing of approximately 101.6 mm. The diode arrangement is suitable for functions such as signal steering, circuit isolation and prevention of unwanted reverse-current paths in compatible industrial control circuits.
With its screw-clamp connection technology and modular open-module construction, the 1SNA020265R0400 is designed for integration into industrial terminal and interface assemblies. It is particularly useful for PLC interfaces, machine controls, relay circuits and process automation systems requiring multiple diode functions within an organised panel layout.
Diodes permit current flow primarily in one direction and are widely used within industrial electrical systems for signal steering, isolation and preventing undesirable reverse-current paths. Where many circuits require this functionality, installing individual discrete diodes can increase component count and wiring complexity.
The TE Connectivity EM16D consolidates sixteen pass-through diodes into a single industrial interface module. This arrangement helps panel builders create cleaner and more serviceable control systems while providing convenient screw-clamp connections for each associated circuit.
