The Allen-Bradley 1734-IV4 is a POINT digital DC sourcing input module. It comes with 4 input points and 4 yellow status indicators, 1 red/green module status indicator and 1 red/green network status indicator, all of which are on the logic side of the module. It has an open-type enclosure and can be mounted using a DIN rail. The 1734-IV4’s compact size of 0.47 x 2.21 x 2.97 inches allows it to be mounted horizontally or vertically in limited spaces. Terminal base units compatible with the 1734-IV4 module are the 1734-TBS, 1734-TB. Recommended wire size for terminating input signals to the module are 22 to 14 AWG solid or stranded copper wire. The 1734-IV4 module. Supports removal or insertion under power (RIUP) which means that even when the entire system is running, users can safely remove or insert the module without disrupting the entire system.

The nominal input voltage of the 1734-IV4 is 24 Volts DC and its POINT bus current is 75 mA. Its nominal input impedance is 3.6 kOhms and its maximum input impedance is 4.7 kOhms. The on-state input voltage is 10 to 28.8 Volts DC, while the on-state current is 2 to 5 mA, with a nominal current of 4 mA at 24 Volts DC. The 1734-IV4 module has a maximum power dissipation of 1W at 28.8 Volts DC, a maximum thermal dissipation of 3.4 BTU/hour at 28.8 Volts DC, and an isolation voltage of 50 Volts. This module comes with a non-condensing relative humidity of 5 to 95% and an operating vibration of 5 g at 10 to 500 Hertz. Its operating shock is 30 g while its non-operating shock is 50 g. The input delay time is 0.5 milliseconds hardware plus the user-selectable time, which ranges from 0 to 65 milliseconds. The 1734-IV4 has an operating temperature range of -4 to 131 degrees Fahrenheit and a storage temperature range of -40 to 185 degrees Fahrenheit.

The 1734-IV4 is a sourcing Discrete Input Modules that belongs to the POINT IO family of IO compact IO modules. This input module features Four (4) 24VDC sourcing channels in a single group.

This input module is used with a POINT IO communication adapter. It also requires a terminal base such as 1734-TB or 1734-TBS to enable field connection. Though the 1734-IV4 supports insertion and removal with active power in the bus, the adapter used with this module must not be removed the same way. This may cause unwanted behavior of the system or cause system error.

For s Series C 1734-IV4, only a ProfiBus adapter is compatible as the communication adapter.

The 1734-IV4 generates 1 Byte of data. Wherein, half of the 1 Byte register is occupied by Channels 0, 1, 2 and 3, starting from bit 0, while the remaining bits are unoccupied specifically, bit 4, 5, 6 and 7.

Filter time are useful with known fluctuations to eliminate false triggering on both the positive and negative sides. Configurable filter times include 0.5 hardware plus 0...63 ms that is user selectable. The module’s operating temperature is 20… +55 °C (-4…+131 °F) while operating shock is 30g and operating vibration is 5 g @ 10…500 Hz. The integrated status indicators of the module include 4 yellow – input status indicators, logic side and 1 green/red as Module Status indicator, logic side and 1 green/red for providing feedback of network status, logic side
