2150EX AV Flow Module - Isco

2150EX Area Velocity Flow System
Section 2 Preparation and Installation
Observe intrinsic safety requirements regarding proximity to
external sources of potential electric or magnetic interference.
Refer to IEC 10079-14 section 12.2.2.5 on installation of cables
and wiring.
If the 2150EX and AV 2150EX sensor are not located in a potentially
explosive atmosphere, the RS232EX isolator cable can be
connected directly to the top of the 2150EX.

2.6.3 Connecting to a 2100
Series Network Device
The 2150EX can be connected to a 2100 Series network device
located in a safe area (with the exception of the 2102 Wireless
module). In order for the 2150EX to communicate with a 2100
Series network device other than the 2194EX, the two must be
connected by an Isco RS485EX Isolator Cable (P/N 60-2004-340).
The hazardous area end, labeled with proper entity parameters,
connects to the EX Network cable.
Observe intrinsic safety requirements regarding proximity to
external sources of potential electric or magnetic interference.
Refer to IEC 10079-14 section 12.2.2.5 on installation of cables
and wiring.
If the 2150EX and AV2150EX sensor are not located in a potentially
explosive atmosphere, the RS485EX isolator cable can be
connected directly to the top of the 2150EX.
A site example using the Field Wizard is shown in Figure 2-2.
