  Dimensions: 2.0" x 11.0" x 6.0"   (5.1 cm x 27.9 cm x 15.2 cm)   Weight: 3 lbs 2.1 oz (1.4kg )

The Allen-Bradley 1785-LT4 is one version of the Classic 1785 PLC-5 Programmable Controller modules. The maximum analog I/O of this module is 512 and the program scan time is 2 ms (discrete logic) and 8 ms (typical). To optimize this scan time, divide the I/O rack between multiple channels. Place the most critical I/O on a single channel, and turn off the I/O on other channels. Because all I/O channels are independent, the remote I/O scan on one channel will not affect remote I/O scan on other channels. The Allen-Bradley 1785-LT4 has 1 DH+ port, the remote I/O transmission rate is 57.6 kbps, and the maximum user memory is 6K words. The Allen-Bradley 1785-LT4 is regarded as Industrial Equipment Class 1, Class A in accordance with Publication IEC/CISPR 11. Without appropriate precautions, there may be difficulties in ensuring electromagnetic compatibility in other environments due to conducted and radiated disturbances. The operating temperature of this module is from -25-60 °C (-13-140 °F). The nonoperating temperature of this module is from -40-85 °C (-40-185 °F). The relative humidity of the 1785-LT4 is from 5-95% without condensation. The operating vibration of this module is 2 g at 10-500 Hz. The Allen-Bradley 1785-LT4 has an operating shock of 30 g (3 pulses, 11 ms). The nonoperating shock of this module is 50 g (3 pulses, 11 ms). The 1785-LT4 has an ESD immunity of 4 kV contact discharges and 8 kV air discharges.
