Module Overview
Section 1.1
Before You Begin
This chapter describes the 1734sc-OE2CIH and the conformally coated 1734sc-
OE2CIHK isolated analog current output modules with HART communication
on two channels. Other than the conformal coating, the modules are identical so
all information applicable to the earlier modules applies to the K versions. Each
channel can be configured for current only or current with HART. This module
provides the following functions:
•
Two isolated output channels that convert a digital code to an analog.
output current.
•
Maximum range is 0 to 21 mA into 0- to 750-ohm loads.
•
Configurable scaling.
•
Configurable limits.
•
Alarm latching.
•
HART master on each channel (can be disabled).
•
LEDs for channel, module, and network status.
