The Allen-Bradley 1764-24AWA is part of the MicroLogix 1500 Programmable Controllers line. This series features controllers for industry whose parts are: base units, processors and accessories. This model is a base unit. The purpose of the base unit is the handle the power supply of the overall controller and it has a set of integrated I/Os. This model provides the user a set 24 I/Os (12 inputs and 12 outputs). The 12 inputs are used to read 120 volts or 240 volts AC signals and the input circuits do not allow adjustable filters, since they have maximum turn-on and turn-off times of 20 milliseconds. The 12 outputs are relay-based (2 per set of outputs). This models does not support high speed I/O. The nominal supply voltage of this base unit is either 120 or 240 volts (may range from 85 to 265 volts) at the frequency of 50 hertz (may range from 47 to 63 hertz). This base unit will work properly in an environment that does not exceed the temperature range going from 0 °C to 55 °C and can be maintained in a storage at temperatures ranging from -40 Celsius degrees to + 85 Celsius degrees. The device can withstand vibrations in the range of frequency going from 10 to 500 hertz, if the intensity of the vibrations is lower than 5 g. If the output relays are operating, aforesaid limit becomes 2 g. The impulse shock that the system can withstand while it is running is 5 g.

The Allen-Bradley 1764-24AWA comes with a line power requirement of 85-265 VAC. When it comes to connectivity, this advanced base unit comes with twelve relay outputs and twelve 120 volts AC discrete inputs. For device communication, this base unit comes with integrated RS-232 communication ports. The Allen-Bradley 1764-24AWA comes with 512 I/O expansion. This advanced MicroLogix 1500 programmable controller is equipped with a bulletin 1764 processor. This replaceable part comes with the following specifications: a power supply, a communication port, and several embedded input and output ports. This base unit was designed to work with compact I/O expansion units. It provides additional I/O to plant facilities. The Allen-Bradley 1764-24AWA is ideal for those who want to reduce their costs of stocking inventory and maximize their option for the embedded I/O. When it comes to power, this base unit requires 120-240 volts AC. Its maximum load power is 16 watts, and its power usage is 70 VA. It requires a line power of 85-265 volts AC at 47 to 63 Hz. When it comes to relays, the Allen-Bradley 1764-24AWA comes with two isolated relays per unit and 12 relay outputs in total. For smooth functioning, an 8 A continuous current is required. Also, for optimal performance, this base unit’s load control should be minimized to 1440 VA. There is a total of 12 inputs with power requirements of 120 volts AC. Unlike other base units in the market, the Allen-Bradley 1764-24AWA comes with a maximum turn-on and turn-off time of 20 milliseconds.
