Information About 1756-OB16E

The 1756-OB16E is part of the ControlLogix digital output family, engineered for applications requiring protected 24V DC sourcing outputs. Its two electronically fused output groups provide improved load management and automatic shutdown in the event of overload conditions. The module offers fast switching response, minimal delay times, and stable current delivery, making it suitable for actuating solenoids, relays, lamps, and similar field devices. Compatible with all ControlLogix chassis and controllers, it supports flexible installation and provides configurable states for program and fault modes to enhance operational safety.

Key Features:

  • 16-Point DC Output Module: Provides sixteen 10–31.2 VDC sourcing outputs for controlling field devices.
  • Electronically Fused Groups: Two independent groups of eight outputs protect against overload and short-circuit events.
  • Fast Switching Performance: Offers 70 µs typical OFF-to-ON and 360 µs ON-to-OFF delay times for responsive actuation.
  • High Output Capacity: Supports 1 A per channel and 8 A maximum per module at 60°C.
  • Surge Handling: Rated for 2 A surge per point for 10 ms, repeatable every two seconds at 0°C.
  • Wide Chassis Compatibility: Works with any ControlLogix chassis for both local and distributed I/O.
  • Diagnostic Flexibility: Supports configurable states in program and fault modes for safety and troubleshooting.
  • Secure Termination Options: Compatible with 1756-TBNH and 1756-TBSH removable terminal blocks.

The 1756-OB16E delivers the reliability and precision required for industrial DC output control within ControlLogix automation systems.

  • Nominal Output Voltage: 24 V DC
  • Output Type: Electronically fused, 16 points divided into two groups of 8
  • Maximum Output Current: 1 A per point at 60°C; 8 A per module at 60°C
  • Power Dissipation: 4.1 W maximum at 60°C
  • Thermal Dissipation: 13.98 BTU/hr at 60°C
  • Backplane Current Draw: 250 mA at 5.1 V DC; 2 mA at 24 V DC
  • Operating Temperature: 0°C to 60°C (32°F to 140°F)
  • Storage Temperature: -40°C to 85°C (-40°F to 185°F)
  • Relative Humidity: 5% to 95% (non-condensing)
  • Isolation Voltage: 250 V continuous between groups of 8 outputs
  • Mounting: Single-slot wide module compatible with any 1756 ControlLogix chassis

This module is ideal for controlling devices such as relay coils, solenoids, pilot lamps, and sirens in industrial automation systems.

Question: What are the wiring requirements for the 1756-OB16E module?
Date Update:04/06/2025
Answer:

The 1756-OB16E module requires a Removable Terminal Block (RTB) or an Interface Module (IFM) to connect all field-side wiring. Compatible RTBs include:

  • 1756-TBNH: Standard RTB
  • 1756-TBSH: Spring clamp RTB

These RTBs are sold separately and are necessary for proper installation and wiring of the module.

Question: How does the 1756-OB16E module handle output delays?
Date Update:04/06/2025
Answer:

The 1756-OB16E module has the following output delay times:

  • OFF to ON: 70 µs nominal / 1 ms maximum
  • ON to OFF: 360 µs nominal / 1 ms maximum

These fast switching times make the module suitable for high-speed control applications.

Question: What certifications does the 1756-OB16E module have?
Date Update:04/06/2025
Answer:

The 1756-OB16E module is certified for:

  • UL (Underwriters Laboratories): Listed as Industrial Control Equipment (File E65584)
  • CSA (Canadian Standards Association): Certified as Process Control Equipment (File LR54689C)
  • CE (Conformité Européenne): Compliant with European Union 2004/108/IEC EMC Directive

These certifications ensure the module meets international safety and electromagnetic compatibility standards.

Question: What are the recommended accessories for the 1756-OB16E module?
