1734sc-OE2CIH
2 Channel HART Protocol Analog Output Module
for Allen-Bradley Point I/O
• Two channels of isolated current and HART protocol output provide a
flexible solution for process applications
• 4 to 20mA current output, 16 bit resolution, 2/4 wire support
• Auto-scanning of HART variables (PV,SV,TV,FV)
• HART Modem per channel
• HART Pass-Through Messaging
• Open circuit detection
• Fault reporting
• 24V Fault Protection
• Removal and insertion under power (RIUP)
• DTM and CONNECTS support allowing interface to your asset
management software
Reduce System Costs
The 1734sc-OE2CIH module maximizes your system performance by combining real-time
HART data acquisition in conjunction with standard analog acquisition and control—at a fraction
of the cost. Simplify commissioning, operation and maintenance. The data may be used as the
foundation for your asset management system.
State-of-the-Art Features
The 1734sc-OE2CIH Analog Output Module provides remote I/O with full analog capability and
the benefit of HART (highway addressable remote transducer) protocol in an I/O module.
The module offers two channels of isolated analog output, each easily configured for current or
current plus HART signals. The 1734sc-OE2CIH also acts as a HART master, allowing communication with HART field devices. HART data is available directly on the Point I/O network.
The Spectrum Controls 1734sc-OE2CIH is compatible with Allen-Bradley Point I/O (EtherNet
and ControlNet) communication adapters. It offers the functionality of dedicated analog output
modules without compromising performance or price.
