About 1794-L34

The Allen-Bradley 1794-L34 is a FlexLogix controller. It has a non-volatile 512-KB user memory available and it supports Logix instructions from the RSLogix 5000 programming software. The 1794-L34 controller also comes with a 1788 communication daughtercard that lets the controller communicate via standard-based DeviceNet, ControlNet, and EtherNet/IP networks. Up to two daughtercards can be installed on this controller. An RS-232 serial port is also available on this controller. Users can install the controller either horizontally or vertically via a panel mount or DIN rail (particularly a 35 x 7.55 millimeters steel DIN rail). The 1794-L34 can handle up to 8 tasks but only 1 can be continuous. This controller supports event tasks, which are consumed tag trigger as well as EVENT instructions. Aside from DeviceNet, EtherNet/IP, and ControlNet communications, the 1794-L34 can also communicate using serial communication, DH-485, and Modbus via ladder routine. 32 connections each can be made over EtherNet/IP and ControlNet.

This controller has a nominal input voltage rating of 24 Volts DC and a range of 19.2 to 31.2 Volts DC that already includes the 5% AC ripple. Its input current is a maximum of 1.33 Amps at 19.2 Volts DC and a maximum of 0.85 Amps at 24 Volts DC. The Flexbus current has a maximum of 653 mA at 5.1 Volts DC and a maximum power dissipation is 25.5 Watts at 19.2 Volts DC and 20.4 Watts at 24 Volts DC. It also has a thermal dissipation of 87 BTU/hour at 19.2 Volts and a non-condensing relative humidity of 5 to 95%. This controller has a non-operating temperature of -40 to 85 degrees Celsius and an operating temperature of 0 to 60 degrees Celsius. The operating vibration of the 1794-L34 controller is 5G at 10 to 500 Hertz and it also has a shock of 30G and 50G, operating and non-operating respectively.
