Allen-Bradley 1734-OB4 Digital Output Module - Reliable Switching Control
The Allen-Bradley 1734-OB4 delivers four independent sourcing digital outputs engineered for controlling solenoid valves, indicator lights, relay coils, and motor starters in distributed automation systems. This POINT I/O module converts controller logic into robust switching signals, providing the interface between your control system and field devices requiring discrete on/off commands.
Output Specifications
- Output Channels: 4 independent sourcing outputs
- Voltage Rating: 10-31.2V DC operating range
- Current Capacity: 2A per output (continuous)
- Output Type: Sourcing (positive switching)
- Switching Speed: 1 kHz maximum frequency
- Overload Protection: Electronic current limiting per channel
- Isolation: 50V continuous channel-to-backplane
- Diagnostic Indicators: Per-channel LED status
- Operating Temperature: 0°C to 60°C ambient
Control Applications
Perfect for pneumatic valve control in packaging machinery where rapid cycling is required, the 1734-OB4 handles high-frequency switching without degradation. Deploy it to energize pilot relays in motor control circuits, activate warning beacons and stack lights for operator notification, or command small DC contactors in material handling systems. The 2A current rating per channel supports most industrial solenoids and relay coils directly without external amplification.
System Configuration
Mount the 1734-OB4 on standard 1734-TB terminal bases for removable wiring convenience. Pair with 1734-IB8K input modules to create complete I/O assemblies. Connect to your network via 1734-AENT EtherNet/IP adapters for seamless integration with ControlLogix and CompactLogix platforms.
Installation Best Practices
Wire field devices to removable terminal blocks using 14-22 AWG copper conductors. Observe proper polarity when connecting sourcing outputs—common terminal connects to DC negative, output terminals switch DC positive to loads. Install external fuses or circuit breakers rated at 2A maximum per channel for additional protection. Use shielded cable for outputs controlling inductive loads to minimize electrical noise.
Technical Q&A
Q: What's the difference between sourcing and sinking outputs?
A: Sourcing outputs (like the 1734-OB4) switch positive voltage to the load with common at DC negative. Sinking outputs switch the negative side. Match output type to your field device requirements.
Q: Can I parallel outputs for higher current capacity?
A: No, paralleling outputs is not recommended and may cause unequal current sharing. For loads exceeding 2A, use external relay or contactor amplification.
Q: How do I troubleshoot a faulted output?
A: Check the channel LED—solid red indicates overcurrent or short circuit. Verify load current is below 2A, inspect wiring for shorts, and confirm proper voltage supply to the module.
Warranty & Support
Backed by our 12-month comprehensive warranty covering manufacturing defects and operational failures. Technical support includes wiring assistance, troubleshooting guidance, and application engineering consultation for integration challenges.
