Information About 1734-IA4
The Allen-Bradley 1734-IA4 is a discrete input module from Allen-Bradley. This module is specifically part of the 1734 POINT I/O system, typically used for implementing distributed I/O applications. This module features Four (4) 120 VAC, non-isolated, sinking input channels and designed to be mounted to a terminal base. The compatible terminal bases for use with this module are 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS wiring base assembly. The 1734-IA4 requires an external power supply to operate. It must be wired to an 85-132 VAC supply source with a frequency of 47-63 Hz while the nominal supply voltage is 120 VAC. It has an isolation voltage rating of 240V, continuous, type-tested @ 3250V DC for 60 s duration. Isolation is between the field-side to the system. The module’s minimum ON-state voltage range is 65 VAC while the maximum On-state voltage range is 132 VAC. It also has a minimum On-state current of 4.0 mA @ 65V AC at 60 Hz; maximum On-state current of 8.5 mA @ 132V AC at 60 Hz. Conversely, the module’s maximum Off-state voltage is 43 VAC, and the maximum Off-state current of 2.7 mA at 43 VAC. This module comes with built-in Module status, Network status, and I/O status indicators. Each I/O channel is provided with an individual LED that replicates the energization status of the module’s channels. An active LED IO indicates an energized input channel otherwise, the channel is de-activated. There is no exact module installation limit, the number of instances is dictated by the supported I/O capacity of the host processor.
The 1734-IA4 is a POINT I/O 120 Volts AC input module in the Allen-Bradley PLC 1734 series. The weight of this digital module is approximately 1.09 ounces. In addition, it has an open-style enclosure type rating and measures 2.21 x 0.47 x 2.97 inches in dimensions. The module’s compact design makes installation easy and makes it possible to mount it horizontally or vertically. The 1734-IA4 has Four (4) 120 Volts AC input with key switch position of Eight (8).
The 1734-IA4 works at a POINT Bus current of 75 mA at 5 Volts DC maximum. It has a power dissipation of 0.50 W at 132 Volts AC and a thermal dissipation of 1.71 BTU/hour at 132 Volts AC and a nominal input impedance of 10.6 kiloohms. The external or input AC power supply voltage of this digital module is 120 Volts AC nominal at a 60 Hertz frequency. Thus, the 1734-IA4 can be utilized at 85 to 132 Volts AC voltage and 47 to 63 Hertz frequency.
