Allen-Bradley 1734-IA4 POINT I/O 120V AC 4-Channel Discrete Input Module

Key Technical Specifications

The 1734-IA4 provides 4 sinking input channels configured as 1 group of 4. It accepts 120 V AC nominal input voltage with an 85-132 V AC range at 47-63 Hz.
On-state voltage ranges from 65 V AC minimum to 132 V AC maximum. On-state current spans 4.0 mA at 65 V AC to 8.5 mA at 132 V AC (60 Hz).
Maximum off-state voltage is 43 V AC with off-state current of 2.7 mA. Nominal input impedance measures 10.6 kΩ for accurate signal detection.
Backplane current draws 75 mA at 5.1 V DC from the POINTBus. Power dissipation reaches 0.50 W at 132 V AC, with thermal dissipation of 1.71 BTU/hour.
Isolation voltage is 240 V AC continuous between field-side and system. The module withstands 3250 V DC for 60 seconds during dielectric testing.
Dimensions are 2.21" x 0.47" x 2.97" (56.0 mm x 12.0 mm x 75.5 mm). It weighs approximately 30.9 g (1.09 oz).

Environmental & Mechanical Specifications

The 1734-IA4 features an open-style enclosure rating. Operating temperature range is -20 °C to 55 °C (-4 °F to 131 °F).
Non-condensing relative humidity tolerance spans 5% to 95%. The module withstands industrial vibration and shock standards.
Wire size accepts 0.25-2.5 mm² or 22-14 AWG copper wire. Terminal screw torque specification is 0.6 Nm (7 lb-in).
