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.
This chapter includes the following information:
•General description.
•Output types.
•Data formats.
•Configurable scaling.
•Configurable limits.
•Alarm latching.
•HART master on each channel (can be disabled).
•System overview and module operation.

User’s Manual Pub. 0300272-03 Rev. B
Section 1.2
General
Description The 1734sc-OE2CIH module provides two isolated output channels with HART
communication to each channel. Each output channel can be configured
individually via software for HART. The module communicates with a 1734
PointBus physical backplane on the main controller.
•You can run up to 19 1734sc-OE2CIH modules when using an Ethernet
adapter.
•You can run up to 9 1734sc-OE2CIH modules when using a ControlNet
adapter.
NOTE
All Spectrum Controls 1734sc modules also function normally when
attached to 1769-L1xprocessors. These processors allow 1734sc modules
to be attached directly to the side and become local IO.
Section 1.3
Output Types The OE2CIH module supports two, user-selectable, current outputs of 4 to 20
mA and 0 to 20 mA.
Section 1.4
Data Formats User-defined scaling is provided that allows you to scale any data sent to the
module to any 16-bit number.
Section 1.5
Hardware
Features The module contains a DeviceNet communications bus that uses a Controller
Area Network (CAN) that connects to an Ethernet adapter for communication
with an external PLC that uses RSLogix 5000. Channels are wired as current
outputs.
Module configuration is done via the controller’s programming software. The
module configuration is stored in the memory of the controller. Refer to your
controller’s user manual for more information.
