Beckhoff - NL1002 - 2-Channel Digital Input Bus Terminal, 24 V DC 

The Beckhoff NL1002 is a 2-channel digital input bus terminal designed for acquiring binary 24 V DC control signals from the process level and transmitting them, in an electrically isolated form, to the higher-level automation unit. Each channel features a 3 ms input filter to suppress bouncing caused by mechanical switches, ensuring reliable signal acquisition. The terminal indicates its signal state via light-emitting diodes (LEDs) for each channel, facilitating easy status monitoring.
