IF30 Powered Input

IF30 Fixed Reader User's Manual
Each of the four inputs is compatible with input signals of 10 to
48 VDC. Both of the high and low signal contacts are exposed
and isolated to 1500V. Input impedance is 1.8K minimum.

In a typical application, the IF30 senses input from an external
control like a switch and then starts a tag read operation.
There are three basic ways to connect input controls to the IF30
input interfaces:
• Supply the input interface with power from the IF30.
• Isolate the IF30 from the input power source.
• Use an open collector solid state drive from a remote device to
control the inputs.
This is the simplest way to connect a control to an IF30 input
interface. If the external control device is a switch, you can
connect one side of the switch to an IF30 +Input pin, and the
other side of the switch to one of the +12 VDC sources, then
ground the corresponding -Input pin.
