About 1794-ACNR

The Allen-Bradley 1794-ACNR is a ControlNet FLEX I/O redundant media adapter module. It has an 8 I/O module capacity and a communication rate of 5 Mbits/s. Including a 5% AC ripple, the module has an input voltage range of 19.2 to 31.2 Volts DC and a nominal input voltage rating of 24 Volts DC. This module’s power consumption is 400 mA when using a 24 Volt external power supply. The maximum Flexbus output current is 640 mA at 5 Volts DC. The module’s maximum power dissipation is 4.6 Watts at 19.2 Volts DC and the thermal dissipation is 15.7 BTU/hour at 19.2 Volts DC. The 1794-ACNR module’s operating temperature is -20 to 55 degrees Celsius and its non-operating temperature is -40 to 85 degrees Celsius. It has a maximum ambient air temperature of 55 degrees Celsius and a non-condensing relative humidity of 5 to 95%. This module also has an operating vibration of 5 G at 10 to 500 Hertz, an operating shock of 30 G, and a non-operating shock of 50 G.

Red and green indicators are present with this module, particularly 1 status indicator and 2 communication indicators. The module can be mounted with a DIN rail mount or a panel mount. The 1794-ACNR module has an open-type enclosure and measures 3.7 x 3.6 x 3.4 inches. The ControlNet protocol is v1.25 and 2 ControlNet BNC ports are present with this module. It can connect to up to 8 terminal base units that have FLEX I/O modules installed, making a FLEX I/O system of up to 8 slots. The power supply used with this module should have a Safety Extra Low Voltage (SELV) or a Protected Extra Low Voltage (PELV) to comply with the CE Low Voltage Directives (LVD).
