Power Connections
The unit is powered from 6-32V DC (36V DC peak) by connecting power as shown
below. This transmitter can be optionally powered (or redundantly powered) via
the DIN rail bus when coupled to an optional DIN rail bus connector (Acromag
Model 1005-063) with a bus terminal block (Acromag 1005-220 or 1005-221). This
optional power connection method can allow several modules to share a single
power supply without wiring power to each power terminal block individually.
•
Power connections are isolated from the input and each output. The
supply voltage should be from 6-32V DC. This voltage must never exceed
36V DC peak, or damage to the unit may result.
•
Variations in power supply voltage between the minimum required and
32V maximum, has negligible effect on transmitter accuracy.
•
Note the placement of earth ground at power. The power cable shield and
DC- should ideally be grounded closest to the module. The input and
output circuit commons are capacitively coupled to earth ground at DC-
through high-voltage isolation capacitors, offering some protection if their
circuits happen to float relative to power (not recommended).
