Information About 1732E-OB8M8SR

The 1732E-OB8M8SR module combines compact, IP-rated industrial design with powerful EtherNet/IP communication capabilities to support distributed I/O architectures across a wide range of automation equipment. It operates within a voltage range of 12–30 VDC and delivers up to 0.5 A per output, with a total module capacity of 4 A, ensuring dependable actuation of field devices. Built-in LED indicators provide clear feedback for module, network, link, power, and I/O states, simplifying field diagnostics. With separate circuits for module and auxiliary power, surge tolerance of 1.2 A, and isolation protection tested at 707 VDC, the module ensures safe, stable operation even under demanding industrial conditions. Its M8 connector interface and EtherNet/IP networking at 10/100 Mbps make integration straightforward in decentralized machine designs.

Key Features:

  • Eight 24 VDC sourcing outputs: each output supports up to 0.5 A, with the full module capable of delivering up to 4 A total for controlling multiple actuators simultaneously.
  • Wide supply voltage range (12–30 VDC): supports diverse power environments while maintaining stable output switching with minimal leakage current.
  • Surge and overload capability: handles surge currents up to 1.2 A for 10 ms every 2 seconds, offering reliable performance with inductive and dynamic loads.
  • Rugged ArmorBlock construction: designed for harsh environments with machine-mounted installation and resistance to shock, vibration, and industrial contaminants.
  • Integrated EtherNet/IP networking: supports 10/100 Mbps communication, full or half-duplex, and up to 100 m cable segments for flexible deployment.
  • Clear status visualization: module, network, link, power, and output LEDs provide immediate diagnostic feedback to reduce troubleshooting time.
  • Dedicated module and auxiliary power circuits: 300 mA module power input and up to 4 A auxiliary power capacity enable isolated and reliable power distribution.
  • High electrical isolation: type-tested at 707 VDC for 60 seconds, ensuring separation between communication, power, and output circuits to protect equipment.
  • Compact footprint: small form factor (179 × 37 × 27 mm) minimizes panel space and supports dense distributed I/O installations.

The 1732E-OB8M8SR delivers the reliability and precision required for high-performance distributed digital output control in modern EtherNet/IP automation systems.

Frequently Asked Questions about 1732E-OB8M8SR
Question: What is the 1732E‑OB8M8SR?
Date Update:19/06/2025
Answer:

It’s a compact, on-machine ArmorBlock I/O module providing 8 sourcing (PNP) 24 V DC outputs, with EtherNet/IP dual-port and scheduled output capabilities. Ideal for protecting networked I/O in harsh environments close to field devices

Question: How do I wire power, I/O, and network connections?
Date Update:19/06/2025
Answer:
  • Use sealed M12 (D-code) connectors for dual EtherNet/IP ports (“Link1/Link2”).
  • I/O cables connect via 3-pin sealed M8 connectors; pin 1 = +24 V, pin 3 = return, pin 4 = output.
  • Power supplied through micro-style 4-pin input/output connectors; supports power daisy-chaining between modules.
Question: What type of outputs does the 1732E-OB8M8SR provide?
Date Update:19/06/2025
Answer:

This module provides 8 sourcing (PNP) discrete DC outputs, each supporting:

  • 12–30 V DC operating range
  • 0.5 A max per channel
  • Short-circuit protection
  • Electronic overcurrent shutdown and recovery

The outputs are designed for resistive or inductive loads (e.g., solenoids, contactors, lights). Output states are restored automatically after fault conditions if wiring and load recover.

Question: How do I configure this module in Studio 5000?
Date Update:19/06/2025
Answer:
  • Add the module to your I/O tree using either:
    An EDS file from Rockwell’s website
    The built-in ArmorBlock catalog in Studio 5000
  • Assign IP address and subnet (use BootP/DHCP tool or port-based assignment)
  • Configure RPI (Requested Packet Interval) for cyclic data exchange
  • Enable Scheduled Output if needed for synchronized CIP Sync operations

All parameters can be adjusted under the module's properties dialog in Studio 5000 Logix Designer.

Question: Can the module operate in extreme or wet environments?
Date Update:19/06/2025
Answer:

Yes. The IP65/IP67/IP69K ratings allow for:

  • Direct mounting without enclosure
  • Operation in washdown areas or dusty environments
  • Temperature range: –20 °C to +60 °C
  • Withstands exposure to water jets, cleaning agents, and mechanical vibration (5 g to 500 Hz, 30 g shock)
  • Use sealed M8/M12 cables and observe installation guidelines for proper sealing.
