Power Options

Below are the power supply options various RobustDC products support. You must see each specific product data sheet for details of the exact options available for that product.

rdcxxxxx dv 12v & 24v (9 to 36v) DC

Accepts unregulated 9 to 36v DC power supply. Suitable for industrial 24vdc supplies, 12v or 24v battery systems, or supply from any low-cost DC transformer pack. Fully in-rush and surge protected.

rdcxxxxx av 9 to 24v AC or DC

Accepts unregulated 9 to 24v AC power or 9 to 36v DC power supply. Suitable for industrial 24vdc or 24vac supplies, 12v or 24v battery systems, or supply from any low-cost AC or DC transformer pack. Fully in-rush and surge protected. -av power option must be ordered with full optical/galvanic isolation.

rdcxxxxx hv 48v ± 20% (38 to 58v) DC

Accepts unregulated 48v DC power ± 20%. Suitable for industrial +48vdc or -48vdc power supplies. Fully in-rush and surge protected. -hv power option must be ordered with full optical/galvanic isolation. It cannot be supplied with partial isolation.

rdcxxxxx gv 12v 24v & 48v (9 to 48v) DC

Accepts unregulated 9 to 48v DC power supply. Suitable for industrial 24vdc & 48vdc supplies, 12v or 24v battery systems, or supply from any low-cost DC transformer pack. Fully in-rush and surge protected.

rdcxxxxx 1ac - 110 vac mains

Accepts mains 110 vac power supply +/- 10%. Unless otherwise stated in the data sheets, includes a wall-mount transformer pack with 2-blade USA style plug.

rdcxxxxx 2ac - 230 vac mains

Accepts mains 230 vac power supply +/- 10%. Unless otherwise stated in the data sheets, includes a wall-mount transformer pack with 2-blade German style plug.

rdcxxxxx 5v - 5v DC ± 5%

Accepts well-regulated 5v DC +/- 5% power supply. Suitable for OEM or panel use with clean, well-regulated power supplies. (NOT SUITABLE FOR BATTERY POWER!)

rdcxxxxx 12v 12v DC +/- 5%

Accepts well-regulated 12v DC +/- 5% power supply. Suitable for OEM or panel use with clean, well-regulated power supplies. (NOT SUITABLE FOR 12V BATTERY POWER!)

rdcxxxxx 24v 24v DC +/- 5%

Accepts well-regulated 24v DC +/- 5% power supply. Suitable for OEM or panel use with clean, well-regulated power supplies. (NOT SUITABLE FOR 24V BATTERY POWER!)

Isolation Options for Non-Fiber Products

 
Most data comm converter/isolator/repeater products have 3 electrical "ports" - 2 "data ports" and 1 "power port". This means you a total of 3 potential grounds to consider. You must see each specific product data sheet for details of the exact options available for that product.
 

rdcxxxxx 2p - Partial 2 of 3 ground 2500v galvanic/optical isolation

2 of 3 ground isolation 
2 of 3 ground isolation means 1 data ground is 100% isolated from both the other data ground and the power supply ground, while the other data ground is assumed the same as the power supply ground. This assumption is Ok if both the device and RobustDC repeater share the same power supply (and therefore the same ground), but it will cause problems if they have subtly different grounds. Note that virtually all "opto-isolated" data comm products on the market are 2-of-3 ground isolation only.

rdcxxxxx 3p - Full 3 of 3 ground 2500v galvanic/optical isolation

3 of 3 ground isolation 
3 of 3 ground isolation means both data grounds are 100% isolated from each other and the power supply ground. In DC powered systems, this is always the safest design option.

Isolation Options for Fiber Optics
 
Any powered fiber optic to electrical data comm converter has 2 electrical "ports" - 1 "data port" and 1 "power port". This means you a total of 2 potential grounds to consider. You must see each specific product data sheet for details of the exact options available for that product.
 
rdcxxxxx 1p - Non-isolated converter

Non-isolated converter 
Non-isolated means this converter assumes the electrical data comm ground is the same as the power supply ground. This assumption is Ok if both the device and converter share the same power supply (and therefore the same ground), but it will cause problems if they have subtly different grounds.

rdcxxxxx 2p - Full 2 of 2 ground 2500v galvanic/optical isolation

2 of 2 ground isolation 
Full 2 of 2 ground isolation means the electrical data comm ground is 100% isolated from the power supply ground. In DC powered systems, this is always the safest design option.

Connector Options
 
Below are the connector options various RobustDC products support. You must see each specific product data sheet for details of the exact options available for that product.
 
rdcxxxxx dd 9-pin D-sub shell connecter
 
Robust DataComm uses only quality parts from vendors with published specs. We know that all of our 9-pin connectors come with at least 30 micron gold plating rated at 500 insertion cycles. 'Gold-plating' results in a consistant layer and thickness of gold on the contacts.

Most other commercial (and 'industrial' products by commercial suppliers) use lowest-cost parts with 'gold-flash' rated at 30-50 insertion cycles. With 'gold-flash' the quantity of gold on the contacts is unknown; it is a variable of the process. It doesn't take many disconnects during troubleshooting to permanently damage 'gold-flash' parts. Insist on quality 'gold-plating' of 30 micron or better.
 
rdcxxxxx cc - Removeable screw terminals with 2.5mm capacity
 
Robust DataComm uses only quality parts from vendors with published specs. We know that all of our screw terminals have consistent force and spring ratings. They will hold your wires indefinitely without vibrating loose.
 
rdcxxxxx st - ST Bayonet-style fiber optic connector
rdcxxxxx sc - SC Subscriber/Standard fiber optic connector
rdcxxxxx fc - FC Ferrule fiber optic connector
rdcxxxxx sma - SMA screw-style fiber optic connector
