About 1734-OB4E

The 1734-OB4E is a POINT I/O Discrete Output module. This module belongs to the Allen-Bradley products for use with Programmable Logic Controller (PLC) and Programmable Automation Controllers (PAC). It is especially compatible with Logix family of controllers such as ControlLogix and CompactLogix automation systems as I/O expansion modules or for implementing distributed I/O systems. The 1734-OB4E features Four (4) Protected output channels, that is capable of providing a 24VDC, within 10-28.8 VDC voltage range with a continuous current rating of 1.0 A per output, not to exceed 3.0 A max per module. This module has internal protection for surge current with maximum rating of 2 A for 10 ms that is repeatable for every 3s. This module has Four (4) yellow output status, Four (4) red output fault status, Two (2) green/red status indicators, each for module and network status reporting. It also has terminals such as Terminal 0 for Output 0, Terminal 1 for Output 1, Terminal 2 for Output 2, and Terminal 3 for Output 3. It also has Four (4) common terminals. The 1734-OB4E may be used to implement automatic and manual control of Final Control Elements (FCE) to carry out control commands, according to the result of logic execution. Compatible FCE devices for this module are ON/OFF devices particularly Motorized and solenoid actuators, Relays and indicating devices such as Pilot Lamps, annunciators and similar devices. Install the module to a mounting base with keyswitch aligned at position 1. Compatible mounting base or terminal base assemblies for this module are 1734-TB or 1734-TBS wiring base assembly. The module assembly is then installed to a DIN rail to form the POINT I/O rack. the 1734-OB4E is compatible for use with all communication adapters with certain rules to follow for compatibility. The module is capable of detecting external short circuit and open loop or wire off conditions. It provides feedback via the provided LED indicators and may also be configured to alert the master controller to be included in the diagnostic buffer for centralized error reporting. Additionally, the provided LED indicators may report the moduleÕs operational status such as additional configuration required, recoverable and non-recoverable fault. The Network status LED may report the moduleÕs state of data communication. The 1734-OB4E including the entire POINT I/O rack must be installed inside an enclosure that provides adequate protection from water drops and jets, dust, heat and other damaging foreign materials. The module is also designed to operate at an operating environment with temperature range of -20...+55 ¡C (-4...+131 ¡F) and maximum surrounding air temperature pf 55 Deg. Celsius. Install an appropriate climate control device temperature with consideration to the moduleÕs Thermal Dissipation of 4.1 BTU/hr. Mechanical disturbances must also be considered such as vibration and shock with operating values of 5 g @ 10...500 Hz and 30 g respectively.
The Allen-Bradley 1734-OB4E is a POINT I/O Discrete Output module. This module has Four (4) Protected source output channels, operating at 10-28.8VDC voltage range. It is compatible with any POINT I/O communication adapters.

F.A.Q for 1734-OB4E

Q: 1. Do I need an external power supply to power the 1734-OBE?A: No. The external power supply required for this module is used to provide power to the output channels. The module is powered up via the POINTBus connection.
Q: 2. What is the moduleÕs POINTBus current rating?A: The module requires 75mA POINTBus current.
Q: 3. How many 1734-OBE modules can I install?A: Install as many as required by the system. Simply follow the 63 module limit of a POINT I/O rack and power extension requirement.

PDFsupply Tech

The 1734-OB4E is a POINT I/O Discrete output module with protected output channels. This output module has Four (4) channels compared to the 1734-OB4 with internal channel protection included. This output module is practical for use in applications with old wiring and presence of electrical noises is confirmed. It is also ideal to be used in applications with higher count of output devices.
