SlotGroup 4 | 1 analog input (±10 V, ±20 mA, 12 bits)
A multi-function analog input is available. Signals either in the range -10/0…+10 V or in the range -20/0/+4…+20 mA can be processed by each channel. The configuration is carried out via SlotGroup 4.
Physically, the voltage and current signals must be connected to different terminal points. The voltage and current input is designed as single-ended. A corresponding channel connection point for the ground reference (AI GND) is also available.
With a technical measuring range of ±107 % of the nominal range, the box also supports commissioning with sensor values in the limit range.

 | Further documentation for I/O components with analog in and outputs Also pay attention to the further documentation: I/O Analog Manual which is available in the Beckhoff Information-System and for download on the Beckhoff website www.beckhoff.com on the respective product pages! The content includes the basics of sensor technology and information on analog measured values. | |
 | Overcurrent protection of the 20 mA inputs The current inputs are protected against damage due to overcurrent by an internal current limiter. Currents > 30 mA can occur. If the error state persists for a longer period of time, the internal current limitation reduces the recorded signal current for thermal reasons, even below 20 mA depending on the ambient conditions. To ensure that the current limiter is not overloaded in the event of a fault, no voltage > 30 V may originate from the source device. Overcurrent is displayed in the process image as "Overrange". Carry out the following steps after an overcurrent has occurred:
