Essential details：1797-ACNR15 Flex Ex ControlNet media adapter
The Allen-Bradley 1797-ACNR15 is a Flex Ex ControlNet media adapter. This module is designed for use with the Flex Ex I/O modules which are specifically compatible for use in hazardous locations that require adherence to a specific level of Intrinsic safety.
The 1797-ACN15 function similarly to a standard ControlNet communication adapter. This module comes with Two (2) ControlNet ports for connection of ControlNet coaxial media cable. It supports linear ControlNet media however, the 1797-ACNR15 is specifically designed for implementation of ControlNet Ex redundant network.
The 1797-ACNR15 supports installation of up to Eight (8) Flex Ex I/O modules. It has IS media type of Ex ib IIB/IIC T4; AEx ib IIC T4; Class I, Division 1 Groups A-G T4 and IS module type of Ex ib IIB/IIC T4, AEx ib IIC T4, Class I Division 1 Groups A-D T4. It supports standard communication rate of 5Mbps with built-in indicators such as Comm A red/grn; Comm B red/grn; Module Status red/grn and Power grn.
The 1797-ACNR15 has a power consumption of 8.5 W, Power dissipation of 8.5 W, Thermal dissipation of 29 BTU/hr. When terminating incoming wires to this module, recommended conductor wire size is 4 mm2 (12 gauge) stranded copper wire with maximum insulation thickness of 1.2 mm (3/64 in.).

1797-ACNR15 Flex Ex ControlNet media adapter
This module is DIN rail mounted device. Only use DIN rail that is made of zinc-plate-yellow-chromate steel DIN rail. It is not recommended to use plastic DIN rails or any other DIN rails made of poor metal conductors or those that are susceptible with oxidation and corrosion. Overtime, DIN rails not made with the recommended material will cause intermittent disconnection of the intrinsic safety ground.
This module provides a simple communication interface between Flex Ex I/O modules and programmable controller processor scanner port along with the I/O communication link. The 1797-ACNR15 has a 24 Volts DC power supply, with 9.5 Watts maximum power consumption, and with an inductance of 120 micro-farads. It has a 5.4 Volts DC of intrinsically safe output, with less than 2.5 Watts output power, and offers Galvanic isolation pathway between the Flexbus and the power supply modules, the Flexbus and the ControlNet modules, ControlNet Ex node and the other node, and the ControlNet Ex and the power supply module.
The 1797-ACNR15 is designed to accommodate a maximum of 8 I/O modules with up to 128 I/O points, and it has a maximum transmission speed of 5 Megabits per second. The 1797-ACNR15 comes in an IP20 rated enclosure with a maximum power dissipation of 8.5 Watts, and an operating temperature range of 20 to 70 degrees Celsius (4 to 158 degrees Fahrenheit). It has fixed LED light indicators which show the communication, module, and power statuses, and it has circuit conductors made of 4.0 millimeters square stranded wire with 1.2 millimeters maximum insulation. The 1797-ACNR15 has an approximate shipping weight of 0.2 kilograms (0.4 pounds), with a total mounting dimension of 94 x 94 x 91 millimeters (3.7 x 3.7 x 3.58 inches), and it is CE, UL, c-UL, IECEx, and FM
