PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1734-IA4 is a discrete input module in the POINT I/O series. This unit provides four 120 VAC non-isolated sinking input channels. The nominal input operating voltage is 120 VAC at 60 Hz. Field supply voltage operates between 85 and 132 VAC at 47 to 63 Hz. The module exhibits a minimum on-state voltage of 65 VAC. Maximum on-state voltage reaches 132 VAC during operation.
The open-style module mounts onto a compatible POINT I/O terminal base. Compatible wiring base assemblies include the 1734-TB, 1734-TBS, 1734-TOP, and 1734-TOPS. It draws 75 mA of POINTBus backplane current at 5V DC. Continuous isolation voltage between the field side and system measures 240V. The system isolation is type-tested at 3250V DC for 60 seconds. Status LEDs indicate conditions for the module, network, and four individual channels.
