3.10.1
Binary Inputs
The BC50R supports two isolated digital inputs. These inputs work with an input
voltage range from 0 V up to 154 V. This input voltage range is independent of the
power supply input voltage. The GPI maximum voltage is the power input voltage.
The BC50R works with a maximum input signal frequency of 10 Hz.
• GPI low level detection is < 6V @ IGPI < 5mA
• GPI high level detection is > 12V @ IGPI > 5mA
3.10.2
Photocouplers
The BC50R provides 2 photocouplers used as shutters (see
Figure 10,
Photocouplers (shutters) - 2 lines
). The shutters are open by default. The outputs are
overcurrent protected and support a maximum output current of 200mA.
