Power:
7-32VDC, SELV, 30mA Max. Class 2
Output Power Supply:
7-32V DC SELV (Safety Extra Low Voltage),
30mA maximum. The supply voltage across the transmitter must not
exceed 36V, even with a shorted load. The supply voltage level must
be chosen to provide a minimum of full-scale current to the load
(0.020*R typical), plus 7V minimum to the transmitter terminals, plus
any line drop. Reverse polarity protection is included, as output
terminals are bridge coupled and not polarized. The ± output polarity
labels on the enclosure are for reference only.
CAUTION:
Do not exceed 36VDC peak to avoid damage to the unit.
Terminal voltage at or above 7V minimum must be maintained across
the unit during operation.
Input to Output Response Time:

Response Time
(Typical)
None
<8 mS

Medium
550 mS
High
800 mS
For a step change in input signal, the output reaches 98% of final value
with a 250
load.
Power Supply Effect:
Less than
0.05% of output span effect per volt
DC change.
USB Interface
Includes a USB socket for temporary connection to a PC or laptop for the
purpose of setup and reconfiguration. During reconfiguration and
calibration, the transmitter receives power from both the USB port and
the output loop--both power sources must be present to calibrate the
unit.
CAUTION:
Do not attempt to connect USB in a hazardous environment.
Transmitter should be setup and configured in a safe environment only.
Data Rate:
USB v1.1 full-speed only, at 12Mbps. Up to 32K commands
per second. USB 2.0 compatible. Consult factory for a low speed
(1.5Mbps) version if required.
Transient Protection:
Unit includes transient voltage suppression on
USB power and data lines.
USB Connector:
5-pin, Mini USB B-type socket, Molex #5000751517.
