Connector plug for monitored outputs (X4)
The B4-EIO input/output unit is suitable for connecting 8 primary outputs. Every output has its own current-limited output
driver which supplies the connected output with power. The outputs are selectively monitored for short-circuits, wire break-
age and overload. You can adjust the strength of the monitoring current (load range) with jumpers. The output current is
consistently limited to 1.5 A (typically).
Connection:
loads 20
