FUNCTIONS
Screw connector functions
3.1

o
The minus contacts are in parallel. One is for the i-LINK and another can be used for
external devices and connections. Plus (+) is for supply voltage.
3.2
Alarm output, AL OUT
o
The AL OUT is activated, when three transmission fails has occurred one after another.
When activated the AL OUT goes to +VDC. Driving current is max. 30 mA.
3.3
+ OUT
o
+ OUT is internally connected to + VDC through an automatic fuse. The supply voltage for
other devices.
o
Connections can be taken from the +OUT.
3.4
Digital Inputs, I1, I2, and Outputs O1, O2
o
Inputs,
o
2 pcs. Activated with + VDC. A transmission is made always when there is a change
in the input (P-to-P). Minimum Voltage for “1”-state triggering is 7 Vdc.

3.6
Indicators
o
ON
o
Power ON/ OFF. Illuminated when +VCD is connected. Blinking, if the device is not
working.
o
O1…O2, PO… PO1
o
Showing the status of the input and output. Illuminated when the consequently
pin is activated.
o
ALARM
