Table 4-1: Connector Description
4.2.2
Power supply
The power supply pins are protected against wrong polarity.
Voltage range: 16V to 52V.
Note
Use inherently limited power sources only!
4.2.3
DIO
The digital Input-Output interface has an optical isolated input and output stage. Driven by the GPIOs 1
(output) and GPIO 3 (input). See the Software User Manual specifications for GPIO functionality.
The output stage is a solid state relais, and gives the possibility to use the output as a simple switcher. The
current is limited to 200mA.
If this interface is used as input, the corresponding output must be set to logically 0. Otherwise the input is
constantly shorted. The maximum LOW input detection voltage is 2V, the minimum HIGH input detection
volte is 5V.
4.2.4
Trigger In
The trigger Input is not optically isolated to minimize the propagation delay. But the input is protected
against 50V clamp voltages. A standard 3.3V TTL signal should be used.
4.2.5
RS485 Mounting Option
For some Applications a RS485 communication could be needed. Therefore the internal hardware could be
modified to route the RS485-A and
–
B signals to the connector in state of DI (RS485-A) and DIGND (RS485-
B).
Ask BECOM BLUETECHNIX for custom modifications.
