4-20 mA Network Bridge

Description
The Model 1400A is a dual 4-20 mA input network bridge. It
bridges industry standard analog 4-20 mA transmitters with LONWORKS network
devices. While the functionality of the Model 1400A is not new, its packaging
allows it to essentially become part of the wiring conduit. One side simply
fastens directly into most standard 4-20 mA transmitters via their 1/2” NPT
wiring entry. The other side of the Model 1400A is a 3/4” NPT that allows
attachment of any standard electrical conduit box. This approach greatly
reduces the amount of wiring and space required for interfacing 4-20 mA sensors
to a LonWorks network.
Although it is very compact, the Model 1400A electronics
include a central processing unit, precision sense resistors, a high-resolution
analog to digital converter, and a network communication interface. The
communication interface is the FTT-10 transceiver. This architecture allows
multiple sensors to be used over a simple four-wire bus installation. Two wires
are used for power, the other are used for digital communication.
