1760-L18BWB-EX

The Allen-Bradley 1760-L18BWB-EX is a Pico Controller with Eighteen (18) I/O signals, suitable for use with expansion modules. This Pico controller is equipped with Twelve (12) digital inputs (at 24 Volts DC) and Six (6) relay outputs. Additional features of this compact controller include a real time clock, Two (2) analog inputs (at 0 to 10 Volts DC), 4 high-speed counters, and a display with a keypad. Its input line power is 24 Volts DC. The 1760-L18BWB-EX is engineered to perform simple logic, counting, timing, and real-time clock operations. It is frequently used during replacement of relays in old applications. This 1760 Pico series controller allows the additional input and output modules to be connected in order to obtain an increase in I/O capacity. An expansion module can be connected to the 1760-L18BWB-EX controller using an expansion module connector (part number 1760-RPLCONN). An advantage of the 1760 Pico series is that the controller and the expansion module can be paired, even when they have different voltage ratings.

The interface of this controller has a status LED, a number of buttons (Alt, Esc, OK, Del, and cursor), an LCD display, and a socket for a memory module or a PC interface cable. The 1760-L18BWB-EX Pico controllers have and operating modes. In Run mode, a stored program is continuously processed until the option is selected or the power is disconnected. In the event of a power failure diagrams, parameters, and settings are retained. This module’s circuit diagram entry is available only when the device is in Stop mode. This Pico controller supports password protection (for a circuit diagram, function relay settings, and system parameters) with a password that consists of a value between 0001 and 9999. The 1760-L18BWB-EX requires fuse wiring protection 1A (slow). Its dimensions are 107.5 millimeters (4.24 inches) x 90 millimeters (3.55 inches) x 56.5 millimeters (2.08 inches). The product’s weight is 0.3 kilograms (10.6 ounces) and operates in a temperature range of -25 to 55 degrees Celsius (-13 to 131 degrees Fahrenheit). This module’s enclosure type is IP20.

The 1760-L18BWB-EX is a Programmable relay that features Twelve (12) 24VDC discrete inputs, Six (6) relay outputs and Two (2) 0 - 10 VDC analog inputs. This product is a Pico Controller manufactured by Allen-Bradley for use in migrating conventional relay logic system to a programmable and modular relay ladder. This controller is capable of implementing discrete controls for actuating motors, valves, contactors, starter, Pilot lamps, annunciators and indicators.

The 1760-L18BWB-EX is incoming line power specifications inlude an input voltage range of 20.4 to 28.8V dc with nominal input voltage of 24VDC and rated input Current of Nominal 140 mA at 24V dc. Allowable voltage dips must be within 10 ms, according to the International Electro-Technical Commission (IEC) EN 61131-2. This controller has a nominal Power Dissipation of 3.5W.

Compatible expansion modules for this controller includes 1760-IA12XOW6I that has Twelve (12) 100-240VAC inputs and Six (6) Relay; 1760-IA12XOW4 which has Twelve (12) 100-240VAC inputs and Four (4) relay; 1760-IB12XOW6I that has Twelve (12) 24V dc and Six (6) Relay; 1760-IB12XOB8 with Twelve (12) 24V dc and Eight (8) Transistor outputs and 1760-OW2 with Two (2) relay outputs. This expansion modules have different line power inputs of 100 to 240VAC and 24VDC. The Pico controller may use this expansion module with different input line voltages.

This Pico controller is capable of replacing conventional relay logic systems and provides an economical way of migrating the hardware relay systems to programmable and modular version. With the use of Pico controller, relays, timers and counters may be eliminated thus reducing panel size.
