Allen-Bradley 1747-SDN Power Supply Module
Know this little workhorse? It’s the 1747-SDN from Allen-Bradley. We’ve seen it keep production lines humming through voltage spikes that would trip other modules. One customer in automotive manufacturing told us it survived 3 consecutive power surges during a factory expansion. Not bad for a 25-year-old design.
| Technical Specifications | |
|---|---|
| Model | 1747-SDN |
| Manufacturer | Allen-Bradley (Rockwell Automation) |
| Type | DC Power Supply Module |
| Dimensions | 2.6″ W × 4.58″ H × 1.1″ D |
| Operating Temp | 0°C to 60°C |
| Input Voltage | 7-30 VDC |
| Current Rating | 250 mA |
| Communication Rates | 1200-38400 BPS |
| Shock Resistance | 30G operating / 50G non-operating |
| Compliance | CE, UL, RoHS |
Still running in legacy PLC-5 systems across multiple industries. We see it most often in:
- Packaging lines (particularly with 1785-L20E controllers)
- Material handling systems
- Legacy batch processing setups
- Older SLC 500 installations needing 24VDC rails
Comes with standard 1746 series backplane interface. Works with most AB communication modules as power source for network interfaces.
Our Advantage:
We’ve got 12 in stock right now (2024Q3). One-year warranty included – not just the 90-day some others offer. Need a different voltage rating? We’ve got modified units available with 24VDC fixed output.
Check availability via WhatsApp or email 2645963284@qq.com. Got a system retrofit? We’ll help match modules to your existing setup.
PS: This isn’t the “program storage device” confusion you see elsewhere – that’s the 1747-PST module. Technical support available 8-5 MST.
