Cypress OPTW-100 Wiegand Splitter, Optically Isolated

The Cypress OPTW-100 is a small interface board for Wiegand wiring problems. It splits or shares a Wiegand signal so you can run two readers into one panel input, or feed one reader into two separate panels. It also isolates the data lines between devices, which helps when two pieces of equipment do not agree on voltage or ground.

Key features

• Connect two readers to a single Wiegand port
• Or connect one reader to two access control panels
• Optical isolation of the data signals between devices
• Bridges Wiegand devices that use different data voltages
• Helps with ground potential differences between devices
• Runs on 5 or 12 VDC, so it can share the reader's power and needs no separate supply

• Manufacturer: Cypress
• Part number: OPTW-100

Before you order

Confirm your readers and panel talk Wiegand, not OSDP or RS-485, since this board handles Wiegand only. Check the supply voltage you plan to share. If both of your devices already sit on the same power and ground, a simple parallel wire run may be enough, and this board may not be needed. Questions about a specific panel?
