Description

The Allen-Bradley 1734-IJ is an incremental encoder module that has one input and a wiring category of 1 on it’s signal ports. It has a key switch position of 2 and an open-type enclosure.

The module is compatible with a 1734-TB, 1734-TBS, 1734-TB3, or a 1734-TB3S wiring base and can mount on a DIN rail or panel with a 22 to 14 AWG solid or stranded copper wire. The module’s current state can be monitored via 5 status indicators, including a red/green indicator for module status, another red/green indicator for network status, and 3 yellow indicators for the A, B, and Z inputs. The yellow status indicators flash when the input is toggling on and off, which is unique to this module.

The 1734-IJ module produces 6 or 10 bytes of input data (scanner Rx) and consumes 1 byte of I/O data (scanner Tx). It returns the frequency of a 24-bit binary number ranging from 0 to 16,777,215, expressed in a 32-bit long word. Every counter is associated with a user-selectable preset value and a roller value. The nominal input voltage of the module is 5 Volts DC, while the input current is 19.1 mA at 5 Volts DC and 25.7 mA at 6 Volts DC. The input off-state maximum current is equal to or less than 0.250 mA, and the voltage is equal to or less than 1.25 Volts DC, while the input on-state maximum voltage is +/-6 Volts, the current is more than or equal to 5 mA, and the voltage is greater than or equal to 2.6 Volts DC.

It also has an operating shock of 30 g, a non-operating shock of 50 g, and an operating vibration of 5 g at 10 to 500 Hertz. Its maximum POINTbus current is 160 mA, its maximum power dissipation is 1.1 W at the rated load, and its maximum thermal dissipation is 3.75 BTU/hour. The module does not require any additional external DC power supply to function.

The 1734-IJ has a continuous isolation voltage of 50 Volts from field-side to system and a non-condensing relative humidity of 5 to 95%. The module’s operating temperature range is -4 to 131 degrees Fahrenheit, and its non-operating temperature range is -40 to 185 degrees Fahrenheit.
