221-1BH50 - DI 16xDC 24V NPN with UB4x
DI 16xDC 24V NPN VIPA 221-1BH50
The digital input module accepts binary control signals from the process
and provides an electrically isolated interface to the central bus system.
The input becomes active when it is connected to ground.
This module requires an UB4x-converter. It has 16 channels that indicate
the respective status via LEDs on the UB4x. The module has to be
connected to the converter module (DEA-UB4x) by means of a flattened
round cable (DEA-KB91C).
• 16 inputs, isolated from the backplane bus
• Active low input (signal level "1" when input is at ground)
• DC 24V nominal input voltage
• Suitable for standard switches and proximity switches
• Status indicator for each channel by means of a LED located on the
conversion module UB4x
