Increase Production Capacity & Minimize System Response Time with New I/O Modules

The latest additions to the ControlLogix® I/O family deliver significant performance improvements. When used in combination, these three new high-speed I/O devices provide peer-to-peer I/O control with nominal screw-to-screw speed less than 100µS, independent of the controller.

1756-IB16IF Fast 24v DC Input Module

• Recognizes input transitions in less than 25µS
• Provides per-point CIP Sync time-stamping with ± 4µS accuracy
• Offers input pattern matching to provide more flexibility in triggering event tasks
• Captures input pulses as low as 10µS

1756-OB16IEF Fast 24v DC Output Module

• Responds to system transition commands in less than 25µS
• Provides configurable durations for fault mode output behavior
• Offers integrated per-point pulse width modulation

1756-LSC8xIB8I 24v DC Low-speed Counter

• Provides eight 40KHz counters as an economical solution for applications requiring multiple counters
• Returns accumulated counts, average and instantaneous frequency, and pulse widths
• Provides 8 isolated inputs for general purpose use or for counter control functions
• Includes 2 output windows that you can define in either frequency or counts
