Allen-Bradley 1769-IF4I

The Allen-Bradley 1769-IF4I compact voltage/current analogue individually-isolated input module has 4 differential isolated inputs each supports an input voltage rating of 30 volts AC/30 volts DC with different input voltage and current ranges starting from -10 volts DC to 10 volts DC and from 0 milliamps to 20 milliamps respectively. The 1769-IF4I has a resolution of 16 bits. This module converts and digitally stores analogue data voltage or current which can be employed by controllers such as the CompactLogix controller or the MicroLogix 1500 controller. The 1769-IF4I module can be employed in several applications mainly in the industrial field. The 1769-IF4I module can be assembled with a 1769-ADN DeviceNet adapter or with a 1769-AENTR Ethernet adapter. The 1769-IF4I module can be mounted on well-grounded panels using two mounting M4 or #8 screws or on either EN 50 022 - 35 x 7.5 or EN 50 022 - 35 x 15 DIN rails. The 1769-IF4I input module dissipates an electrical power of 3 watts. The 1769-IF4I module has an OK status indicator which indicates that this terminal has power, has run internal diagnostics and can communicate over the network. This Allen-Bradley 1769-IF4I employs a digital programmable filter which provides noise rejection for the input signals. This Allen-Bradley 1769-IF4I voltage/current analogue individually-isolated input 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 that match the input transmitter specifications except when connected to a MicroLogix 1500 base with a current consumption of 140 milliamps. The normal impedance of the 1769-IF4I module is 1 mega-ohm for the voltage input and 249 ohms for the current input. This 1769-IF4I module supports shielded or twisted-pair Belden 8761 wire or equivalent wires. The 1769-IF4I Allen-Bradley 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-IF4I module can be configured as engineering parameters in milliamps or volts, percent of range, for PID, raw /proportional data for high resolution. The 1769-IF4I analogue module is intended for use in a mainly industrial environment that is clean and dry. This module weighs approximately 300 grams (0.65 pounds) while shipping. This Allen-Bradley module works properly at 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit).

The 1769-IF4I is an analog current/voltage isolated input module by Allen-Bradley in the 5370-controller lineup. This module converts analog data and stores it digitally for use by CompactLogix and MicroLogix 1500 controllers. This unit features an LED to indicate faults and can check for errors in configuration, open circuit, under and over range faults. It has removable terminal blocks to allow easy installation. Four (4) individually isolated input channels are provided.

Belden 8761 shielded cable or equivalent are recommended for this module. This module receives 5 volts direct current (DC) and 24 volts direct current from the bus interface. It accepts 0 to 20 milliamperes and 4 to 20 milliamperes of current input and voltage inputs of +/-10 volts direct current, 1 to 5 volts DC, 0 to 5 volts direct current, and 0 to 10 volts direct current are supported. Since the inputs are isolated, mixed types of inputs are supported. Differential signal wiring is supported.

The module uses a Delta-Sigma converter to process data and converts it to a 16-bit integer. The processed data is configurable and can be interpreted as scaled for PID, engineering units, raw data, and the percent range. This module has a power supply distance rating of 8 and is rated for heat dissipation of 3 watts. It may be panel mounted or mounted using a DIN-rail. It has an open enclosure measuring 4.65 inches x 3.43 inches x 1.38 inches.
