1746-IV32

1746-IV32 is an SLC 500 32 channel digital input module produced by Allen Bradley. This is a 24V DC current source input module with 32 inputs and 8 fused common points, fixed in any slot of the SLC 500 chassis. Its operating voltage range is 15 to 30V DC at 50 ° C, 15 to 26.4V DC at 60 ° C, and the bottom plate draws a current of 0.05A at 5V DC. 1746-IV32 has a non replaceable electronic fuse with a rated value of 2.5A and provides a 60s 1500V AC test isolation backplane. The maximum delay time of the signal at the input point in the open and closed states is 3 milliseconds, and the maximum closed state current of the module is 1.5 milliamperes. It also has a minimum open state voltage of 15V DC and a maximum closed state voltage of 5V DC. The nominal input current of each point is 5.1mA, and the maximum heat dissipation of each point is 0.2W. The total heat dissipation of the entire module is 6.65W. 1746-IV32 has passed CE, CSA, and UL certifications and provides NEMA standard ICS 2-230 immunity. Its design and testing can withstand 2.5G working vibration at 57-200Hz, with a peak displacement of 0.015 inches during testing, maintaining optimal functionality even under 30G working impact. Its working temperature is between 0 and 60 degrees Celsius, and the relative humidity range is 5-95%.

Alan Bradley 1746-IV32 is a discrete input module and a component module of the SLC 500 product series. This module is a 24V DC source input module, with thirty-two (32) input channels divided into four (4) groups, each with eight (8) channels.

Each channel of this module operates within the voltage range of 15 to 30 volts DC at 50 degrees Celsius and 15 to 26.4 volts DC at 60 degrees Celsius. Its bottom plate current consumption is 0.050 amperes at 5 volts DC, 0 amperes at 24 volts DC, and isolated from the 1500 volt AC bottom plate channel for 1 minute.

The maximum signal delay of the module channel for switching on and off is 3 milliseconds. The minimum on state voltage is 15.0 volts DC, while the maximum off state voltage is 5.0 volts DC, and the maximum off state current is 1.5 milliamperes. At 24 volts DC, the nominal input current of the module is 5.1 milliamperes. Its single channel heat dissipation is 0.20 watts, with a total heat dissipation of 0.25 watts.

1746-IV32 has four (4) series, particularly the A, B, C, and d series. A. Each input common terminal of the B and C series is equipped with a fuse, which means that four (4) internally installed non replaceable fuses are part of the series. The D-series module does not have an internal group fuse.

1746-IV32 can be installed on any SLC 500 chassis. Similarly, it can be used as an input module for any SLC 500 processor. It can also be installed in local I/O racks, expansion racks, and distributed I/O racks.
