PSI302P
Fieldbus Power Supply Impedance

The Fieldbus Power Supply Impedance is a non-isolated, active impedance control device. In accordance with Standard IEC 1158-2, this device presents an output impedance which, in parallel with the two bus terminator (a 100W resistor in series with a 1mF capacitor) required by the standard, results in a purely resistive line impedance for a broad frequency range.

The PSI302P, because of the power supplied, cannot be used directly in areas requiring intrinsic safety specifications.

Some Characteristics:

Number of channels	2 or 4
Output	320 mA (max.)
Power Supply	24 to 32 Vdc ±10%
Ambient Temperature Limits	-20 to 50 ºC (-4 to 122 ºF)
Ambient Humidity Limits	10 to 95% RH
Weight	230 g
Dimensions	1.57 x 5.57 x 5 (in) 39.9 x 14.5 x 127 (mm)
