Allen-Bradley 1769-OF4CI

The Allen-Bradley 1769-OF4CI compact current analogue individually-isolated module contains 4 differential isolated outputs each supports a voltage rating of 30 volts AC/30 volts DC with multiple output current ranges starting from 0 milliamps to 20 milliamps. The 1769-OF4CI provides a resolution of 16 bits. This module converts and digitally saves analogue data current which can be employed by controllers such as the CompactLogix controller or the MicroLogix 1500 controller. The 1769-OF4CI module can be employed in several applications mainly in the industrial field. For example, the 1769-OF4CI module can be assembled with a 1769-ADN DeviceNet adapter or with a 1769-AENTR Ethernet adapter. The 1769-OF4CI module offers the flexibility during the installation and mounting steps with two mounting M4 or #8 panhead screws for well-grounded panel mounting or on a DIN rail. The 1769-OF4CI output module dissipates an electrical power of 2.68 watts. The 1769-OF4CI module has an OK status LED indicator which indicates that this module has power, has run internal diagnostics, and can communicate over the network. This Allen-Bradley 1769-OF4CI current analogue individually-isolated output module can be supplied through 1769 Compact I/O power supplies such as 1769-PA2, 1769-PB2, 1769-PA4, 1769-PB4 which are Class 2-rated power supplies except when connected to a MicroLogix 1500 base with a current consumption of 145 milliamps. The normal impedance of the 1769-OF4CI module is 1 mega-ohm. This 1769-OF4CI module supports shielded or twisted-pair Belden 8761 wire or equivalent wires. The Allen-Bradley 1769-OF4CI output module can be connected easily to either the controller or to an adjacent I/O module before or after mounting. The data of the 1769-OF4CI module can be configured as engineering parameters in milliamps or volts, percent of range, for PID, raw /proportional data for high resolution. The 1769-OF4CI analogue module is intended for use in a mainly industrial environment that is clean and dry. This Allen-Bradley module weighs approximately 270 grams (0.6 pounds) while shipping. This Allen-Bradley module works properly at 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit).

The 1769-OF4CI, which is a product that was manufactured by the Allen-Bradley company, is an analog output module. Belonging to the 1769 Compact I/O system product line of Allen-Bradley, this module was designed to be compatible with numerous controllers, such as the CompactLogix and MicroLogix 1500. This module offers support with the Belden 8761 shielded cable.

The output current signals of this Allen-Bradley device are zero to twenty (0 to 20) milliamperes and four to twenty (4 to 20) milliamperes, with a full analog current range of zero to twenty-one (0 to 21) milliamperes and three-point-two to twenty-one (3.2 to 21) milliamperes, respectively. The heat dissipation rating of this unit is 2.68 total watts. The maximum conversion rate for all channels is one hundred and ten (110) milliseconds (ms). The step response time until the module gets to 63% of its full range is less than two-point-nine (2.9) milliseconds. The resistive load on current output for this unit is zero (0) to five hundred (500) ohms (this includes wire resistance). Additionally, this unit's maximum inductive load comes in at 0.1 millihenry.
