The 1769sc-IF8u can reduce system costs replacing dedicated analog I/O modules with one
module. The 1769sc-IF8u module can replace analog input, thermocouple and RTD modules
without compromising performance. Mix and match input types to reduce your analog I/O
module count. Installation is simplified and costs are reduced by using a common I/O within
your system.
• Eight channels of voltage, current and thermocouple or 4 channels of
RTD/resistance input provide a flexible solution for applications
requiring mixed analog input.
• Any combination of input types may be used at one time.
• Features 500 Vdc channel-to-backplane isolation; 500 Vdc channel-tochassis
ground isolation; 10 Vdc channel-to-channel isolation.
• Easily configured by ladder register settings and on-board jumpers.
• Channel selectable filtering for maximum speed with minimum noise.
• Fully auto-calibrating for best possible accuracy.
• Cold junction compensation included for thermocouples.
• Low power consumption.
The broad variety of input types and configuration options provide unsurpassed flexibility and
simplify integration. Features such as input type, open circuit detection, high and low range
alarms are individually programmable for each channel. Accuracy is comparable to dedicated
analog input modules. The module incorporates proprietary Allen-Bradley ASIC technology
insuring operation and performance mirror existing Allen-Bradley products. Configuration is
accomplished using existing programming software.
The Spectrum Controls 1769sc-IF8u is compatible with Allen-Bradley MicroLogix 1500 and
CompactLogix controllers. It offers the functionality of dedicated analog input modules without
compromising performance or price.
