Allen-Bradley 1734-OE2V

The Allen-Bradley 1734-OE2V is a POINT I/O Analog Output Module. It has 2 single-ended, non-isolated, voltage output with range of 0-10VDC or +/- 10VDC. It has an integrated analog to Digital converter circuitry with conversion resolution of 14 Bits and absolute accuracy of 0.1% full scale @ 25 °C.

The 1734-OE2V is an analog output module capable of producing Voltage signal with range of 0-10VDC or +/- 10VDC. This module is manufactured by Allen-Bradley for the POINT IO product family of compact emote IO modules.

Analog output modules are used to control modulating devices such as Control Valves, Variable Frequency Drives (VFD) or Variable Speed Drives (VSD), Dampers, Louvers and other converters and actuators.

The analog output comes from the internal conversion of digital data within the Programmable Logic Controller’s (PLC) register. The digital data is converted with the use of Digital to Analog converter circuit that is integral to the module. The digital data being converted may come direct manipulation of a PLC register, a result of a mathematical operation, pre-defined values or output of a Proportional-Integral-Derivative (PID) controller.

Aside from actuators, analog output signals from this module may also be used to interface with remote indicators, data loggers, recorders or even used as a pass through or signal multiplexer.

This module requires a wiring base assembly of 1734-TB, 1734-TBS, 1734-TB3, 1734-TB3S,1734-TOP, or 1734-TOPS wiring base assembly. It has integrated indicators such as 1 green/red for module status, 1 green/red for network status and 2 green/red for output status. This module keyswitch position is No.4. When wiring signal to this module, the recommended wire size are 0.25 to 2.5 sq. mm. or 22 to 14 AWG solid or stranded copper wire rated at 75 °C or 167 °F or greater and max insulation of 1.2 mm or 3/64 in.

The Allen-Bradley 1734-OE2V POINT I/O Analog Output Module with single-ended, non-isolated 2-channels that converts digitally processed data to analog output voltage. The module has a resolution of 14 bits (13 plus sign) 1.28C/cnt in unipolar or bipolar modules. Until the communication is set, it has a 0V output voltage. Its user-configurable output voltage is 0-10V. (-0.0V under, +0.5V over) +10V user configurable (-0.5V under, +0.5V over). The 1734-OE2V operates Uni-polar or Bipolar modules. Its default module mode is 0-10V DC and it has a typical mode of -10 - +10V DC. It has a default scaling point of 0 - 10000. The 1734-OE2V’s absolute accuracy comes with a 0.1% full scale at 25°C. Its accuracy drift with temperature is 5ppm/deg. C.

The Allen-Bradley 1734-OE2V has a current load on the voltage output of 3 mA with a digital to analog conversion type. Its conversion rate is 20’s, it is factory-calibrated, and it has a format of signed integers. Its max point-bus current is 75 mA at 5V DC and it has a max power dissipation of 1W. Its thermal dissipation is 3.4BTU/hr. The 1734-OE2V has an isolation voltage of 50V continuous and the module has been tested to withstand 2200V DC at 60 s. It has a nominal voltage of 24V DC and a voltage range from 10-28.8V DC. Its current supply is 35 mA at 24V DC including outputs of 3mA.

The 1734-OE2V has several indicators: 1 green/red for the module status, 1 green/red for the network status, and 2 green/red for the output status. Its dimensions are 56 x 12 x 75.5 mm. Its wire category is 1 on the signal ports. The model’s wire size is 0.25-2.5 mm2 solid or stranded copper wire rated at 75 deg. C or greater with 1.2mm insulation max. The 1734-OE2V weighs approximately 36g and its terminal base screw torque’s mass is 0.6 Nm. It has an operating temperature of -20-55 deg. C, a maximum air surrounding temperature of 55 deg. C, and a storage temperature of -40-85 deg. C. The 1734-OE2V has a relative humidity of 5-95% non-condensing and a vibration of 5g at 10-500 Hz. Its operational shock is 30g and its non-operational shock is 50g. The 1734-OE2V module produces 0 Volts output before communication is established. Once communication is established, the output voltage is user-configurable anywhere from 0-10 Volts. Additionally, the 1734-OE2V module’s current load on voltage output is 3 mA.
