The Allen-Bradley 1734-IM4 is a POINT digital AC input module. It comes with 4 non-isolated sink inputs in a group and with a key switch position of 8. Status indicators let users see the current network status, module status, and the status of the inputs. It has an open-style enclosure and can be mounted using a DIN rail. The 1734-IM4 module can only use a 22 to 14 AWG solid or stranded copper wire. It has a total measurement of 2.21 x 0.47 x 2.97 inches and a weight of 30.9 g or 1.09 ounces.

The 1734-IM4’s on-state voltage ranges from 159 to 264 Volts AC with a nominal voltage of 220 Volts AC at 60 Hertz. The on-state current ranges from a minimum of 6.2 mA at 159 Volts AC and 60 Hertz to a maximum of 10.2 mA at 264 Volts AC and 60 Hertz. The 1734-IM4 module also has a maximum POINTbus current of 75 mA at 5 Volts DC. The delay time of the 1734-IM4 for both ON to OFF and OFF to ON is 20 milliseconds hardware filter, plus a 1-65.535 milliseconds digital filter, which is programmable in increments of 1 millisecond. It comes with a nominal input impedance of 22.3 kiloohms, a maximum power dissipation of 0.80 Watts at 264 Volts AC, and a maximum thermal dissipation of 2.73 BTU/hour at 264 Volts AC. The 1734-IM4 also has a continuous isolation voltage of 240 Volts from the field-side to the system.
