Module Specifications
NOTE: A re-designed F2-08AD-1 with a single circuit board design was released in 2009. The jumper link location is different. See
Setting the Module Jumpers on page 4-6. Also, some specifications were changed on page 4-3. Otherwise, the re-designed module
functions the same as the prior design.
The F2-08AD-1 Analog Input module provides several
hardware features:
• Analog inputs are optically isolated from the PLC logic.
• On-board 250 ohm, 1/2 watt precision resistors provide
substantial over-current-protection for 4-20mA current
loops.
• The module has a removable terminal block so the
module can be easily removed or changed without
disconnecting the wiring.
• With a DL240, DL250-1 and DL260 CPU, you can read
all channels in one scan.
Firmware Requirements:
To use this module with a D2-230 CPU the CPU must have
firmware version 1.6 or later. To use the pointer method of
writing values, D2-240 CPUs require firmware version 2.2
or later. All versions of the D2-250-1 and D2-260 CPU’s
firmware support this module and the pointer method.

Analog Input Configuration Requirements
The F2-08AD-1 appears as a 16-point discrete input module and can be installed in any
slot of a DL205 system. The available power budget and discrete I/O points are the limiting
factors. For more information regarding power budget and number of local, local expansion
or remote I/O points, check the user manual for the particular CPU model and I/O base
being used
