The Allen-Bradley/Rockwell Automation 440R-M23084 is a type of single-function guardmaster safety relay. It comes with 02 N.O safety outputs. The maximum allowable input resistance on this relay module is 135 Ohms. Twenty-four (24) volts alternating current/direct current (AC/DC) is this device's rated power supply. It is part of the safety relays guardmaster from Allen-Bradley. It is ideal for use in multiple industrial applications. However, it is best suited for particularly machine safeguarding systems. Thanks to its universal housing design, and other advanced configuration options, primarily it is ideal for use in a number of applications.

It supports 4 different configuration options. The configurations include 2 normally closed contacts, and 1 normally closed contact. There is also 2 P&P connections o this safety relay. The P&P connection originates from a light curtain. As mentioned earlier, the Allen-Bradley 440R-M23084 single-function guardmaster safety relay support 3 input options. You can use 2 normally closed contacts, a light curtain, and 1 normally closed contact with this module. It comes with 2 normally open contacts as safety output options.

The Allen-Bradley 440R-M23084 single-function guardmaster safety relay comes equipped with a safety output delayed option. It consists of 2 normally open contacts, and 1 normally closed contact. The power supply voltage rating on this module is 24 volts alternating current and direct current.  0.15 to 3 milliseconds is the standard time delay rating for this module. 99 and 114.5 millimeters are the widths, and height of this module respectively. The depth of this module is 45 millimeters. 4 watts is the power consumption rating for this safety relay module. It comes with an infinite simultaneity rating. 135 ohms is the maximum allowable input resistance rating on this module. Users can monitor the reset options either manually, or automatically.
