Frequently Asked Questions

Which controllers can use 1769 Compact I/O modules as local I/O?
The 1769 Compact I/O modules can be used with 1769 CompactLogix controllers, for expansion I/O in a MicroLogix 1500 controller assembly, in an assembly with a 1769-ADN DeviceNet adapter, or in an assembly with a 1769-AENTR Ethernet adapter. The number of supported local I/O modules depends on the specific controller; for example, the 1769-L36ERM supports 30 local modules across 3 separate banks.
What are the operating temperature limits for most 1769 Compact I/O modules?
The operating temperature range for most 1769 Compact I/O modules is 0…60 °C (32…140 °F), tested per IEC 60068-2-1, IEC 60068-2-2, and IEC 60068-2-14. The non-operating storage temperature range is -40…+85 °C (-40…+185 °F). Environmental specifications for the 1769-SM2 module are listed separately in the publication.
How are 1769 Compact I/O modules mounted and connected together?
Modules can be installed on a panel with two mounting screws or on a DIN rail. They mechanically lock together using a tongue-and-groove design, and an integrated communication bus is connected from module to module by a movable bus connector. Once locked together, the system forms a single assembly.
How many expansion cable segments can be used in a 1769 system?
A maximum of two expansion cables (1769-CLLx, 1769-CRRx, or 1769-CRLx) can be used in a 1769 system, which allows for up to three groups or banks of I/O modules. Each bank requires its own power supply. Cables are available in 305 mm (1 ft) and 1 m (3.28 ft) lengths.
What hazardous location rating do the 1769 Compact I/O digital modules carry?
The 1769 Compact I/O digital and contact modules are c-UL-us Listed for Class I, Division 2, Group A, B, C, D Hazardous Locations, certified for the U.S. and Canada under UL File E334470. The 1769-ECR/ECRK end caps also carry ATEX and IECEx Zone 2 certifications.
What is the maximum current output of the 1769-OB8 high-current output module?
The 1769-OB8 solid-state 24V DC source output module provides a maximum of 2.0 A per point and 8.0 A per module at 60 °C (140 °F). It supports a surge current of 4 A for 10 ms, repeatable every 2 s, and operates over a voltage range of 20.4…26.4V DC.
What wire sizes are compatible with 1769 Compact I/O terminal blocks?
Most 1769 Compact I/O modules accept 22…14 AWG solid wire or 22…16 AWG stranded wire. The wire type must be Cu-90 °C (194 °F). Terminal screw torque is 0.68 N•m (6 lb•in) and retaining screw torque is 0.46 N•m (4.1 lb•in).
