Electrical Interfaces & Connectors
Interfaces list, specifications and precautions
System Port
- aggregates following interfaces:
USB 2.0 High speed interface
Expansion for more than one USB device is possible using a standard powered USB hub or system
breakout box. USB Interface and its ground is galvanically connected to the housing.
Y
Maximum DC
load of the USB VCC is 100mA peak. Cable must conform to USB standard both in terms of character-
istic impedance and shielding.
RS-232 Serial Interface
Standard RS-232 serial port for up to 1Mb/s transfer rate. Rx and Tx data only, no hardware hand-
shake signals. RS-232 Interface and its ground is galvanically connected to the housing.
Digital Inputs
Four user configurable, high speed, isolated current mode inputs with one ground common line. Can
by readily used with 5V high side switched sources.
Y
For higher then 5V Vin sources the current
shall be limited to 10mA by adding a serial resistor Rs according to the following equation:
Rs= (Vin-1.5)/0.01-360
Digital Outputs
Four user configurable, high speed, isolated open collector, low side switched outputs with one com-
mon ground line and isolated auxiliary 5V common source.
Y
Maximum current load per switch is
100mA.
Y
Maximum open switch voltage is 24V DC.
Y
No inductive loads are allowed.
Y
Maximum
current load for the 5V digital outputs common source is 60mA.
See the
“Digital I/O interfaces cookbook”
application note at CURRERA online support area.
Power Supply Input
Provides optional power supply feed where PoE is not available. 12-48V DC 7-13.5W, maximum allowed
ripple 200mV.
Y
Power Supply input is isolated towards the device electronics and the housing and
has 200V isolation limitat towards Ethernet signals. Shall your Ethernet wiring require more than
200V isolation, you must use PoE or ensure that your power supply provides required isolation.
Gigabit Ethernet with PoE
1000BASE-T IEEE802.3af compliant Ethernet interface with Power Over Ethernet (PoE) Class 0.
Display output
Analog RGB display output, 75 ohms impedance, VESA compliant with resolution up to 1600x1200
pixels.
