Model 1400A: Dual 4-20 mA Network Bridge
Datasheet
XIF File
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.
