Description
The Allen-Bradley 1756-OB16IEFS is a high-performance ControlLogix digital output module featuring 16 individually isolated, electronically protected DC output channels. Operating across a flexible 10 to 30 VDC voltage range, it supports sinking and sourcing output configurations alongside scheduled timestamps for high-speed motion control, packaging, and high-precision event execution.
Scheduled Execution and Channel Isolation
Designed for time-critical industrial applications, the module supports scheduled output data execution synchronized with the system CIP Motion or CIP Sync clock. This allows output channels to turn on or off at precise microsecond-level timestamps rather than waiting for controller scan cycles.
Each of the 16 output points features channel-to-channel electrical isolation, preventing ground loops and cross-channel interference. Integrated electronic protection safeguards output channels against overcurrent conditions, short circuits, and thermal overloads without requiring physical inline fuses.
Backplane Integration and Wiring Accessories
The 1756-OB16IEFS installs into any standard ControlLogix 1756 chassis slot, leveraging producer/consumer communications for fast diagnostic status reporting, wire-off detection, and individual point fault messaging back to the controller.
Field signals require a 36-pin Removable Terminal Block (RTB) housing, such as the 1756-TBCH (cage clamp) or 1756-TBS6H (spring clamp). RTBs allow complete wiring harnesses to be disconnected during maintenance without removing individual channel connections.

Frequently Asked Questions
Q: What is the main difference between the 1756-OB16IEFS and standard ControlLogix output modules? A: The 1756-OB16IEFS provides high-speed scheduled output switching tied to precise system timestamps, along with individual channel-to-channel isolation and integrated electronic overcurrent protection.
Q: Can the 1756-OB16IEFS module be wired for both sinking and sourcing loads? A: Yes, the module supports flexible 12/24 VDC sinking and sourcing topologies across its 16 isolated output points depending on field wiring configurations.
Q: Is a removable terminal block included with the 1756-OB16IEFS module? A: No, 36-pin terminal block assemblies such as the 1756-TBCH or 1756-TBS6H must be ordered separately.
