FOXBORO 0 to 20 mA Input Interface Module FBM01

FOXBORO 0 to 20 mA Input Interface Module FBM01
The 0 to 20 mA Input Interface contains eight
20 mA dc analog input channels. Each channel
accepts a 2-wire, analog sensor input such as a 4 to
20 mA transmitter or a self-powered 20 mA source.
The module performs the signal conversion required
to interface the electrical input signals from the field
sensors to the redundant Fieldbus. The module is a
main type, and independently connects to the
redundant Fieldbus.

This module executes the analog Input application
program. The configurable options for this program
are Analog Input Resolution (on a per module basis),
Fieldbus Switching Enable, and Fieldbus Switching
Time.
FUNCTIONAL SPECIFICATIONS
Input
8 isolated and independent channels

Isolation
The module will withstand, without damage, a
potential of 600 V ac applied for one minute between
any channel and earth (ground), or between a given
channel and any other channel.
NOTE
This does not imply that these channels are
intended for permanent connection to
hazardous voltage circuits. Connection of
these channels to voltages greater than
30 V ac or 60 V dc will violate electrical safety
code requirements and may expose users to
electric shock.
