I/O Module UE20-16DI-N DI module,16 ports, NPN,24VDC
Discover the UE20-16DI-N digital input module with 16 channels, NPN signal type, 2-byte data size, reverse protection, and photoelectric isolation.
Description
- The digital input module has 16 channels, and the width is only 12 mm.
- Support source type input, input NPN type low level effective.
- It can receive field side (such as: sensor, encoder, switch or proximity switch) binary control signal.
- The module adopts Push-in CAGE CLAMP technology, which allows a single strand of wire to be inserted directly.
- Each input channel can be set filtering time.
