Figure 2-13: Analog Output Wiring
The KFD2-STC4-EX1 analog isolated barrier produced by P&F (certificate numbers: IECEx BAS
04.0016X; BAS 99 ATEX 7060X) has been verified and can be connected directly with the
IND256x intrinsically safe analog 4-20 mA option, and then connected to a PLC or DCS system in
the safe area.
2.7.5. Wireless Communication
IND256x wireless communication option board is installed on the mainboard with other option
boards, and is not connected with peripherals. The option should be configured as described in
Chapter 3, section 3.8.4. A strong WiFi signal is required to achieve wireless communication with
peripherals.
The IND256x supports a single WiFi option.
This option cannot be used together with the intrinsically safe analog 4-20 mA output option.
