FR01DxDR
RedLink® Fiber Optic Receiver
for Direct High Voltage Switching
Datasheet
FR01DxDR Revision A
1
DESCRIPTION
This Firecomms RedLink® receiver is based on a fully
integrated photodiode with TIA, limiting amplifier
and a MOSFET open drain output to handle
switching of voltages in the range from 3 to 20 V
(e.g. 3.3, 5, 12, 15 V). The part also includes an
optional 1 kΩ pull-up resistor R
L
.
Housed in non-conducting plastic the RedLink®
receiver connector is blue. The housings are
compatible with the Versatile Link style of fibre plug
and are optimized for use with Plastic Optic Fibre
(POF).
The receiver operates over the industrial
temperature range of -40 ⁰C to +85 ⁰C supporting
many industrial applications where reliable
command and control response is required in
electrically harsh environments.
The receiver is typically used at low switching
speeds where 12 V and 15 V power electronic
devices are being switched at kHz speeds but can
operate up to 1 MBd if required.
