The O-57419- unit is a 5-24 VDC Input Module that was made by Reliance Electric for the AutoMax series of PLCs. If you find yourself in need of this product, then AX Control is the place for you. We typically have this product in stock even though it is no longer being shipped out by Reliance Electric.
The O-57419- Input Module is designed to accept up to 32 low-level DC input signals, which can range from 5 to 24 volts. These inputs can either be NPN open collector outputs or contact closures. Both of these configurations demand the use of an external power supply. Four of the inputs on the O-57419- Input Module have the ability to be programmed along with latch pulses of 0.7 milliseconds or longer. These same inputs also have the ability to be used to generate an interrupt. In addition to all of that, the O-57419- Input Module contains eight isolated commons, which means that there is one common for reach group of four inputs.
In most cases, the O-57419- Input Module will be used to control the power of certain low level DC devices. Examples of these such devices include: relay contacts, thumbwheel switches, push buttons, limit switches, buffered high speed CMOS, buffered LSTTL, and open collector TTL.
The O-57419- Input Module’s faceplate has a total of 32 status indicator LEDs that show the status of each input. These input signals will be taken to the module by the use of a multi-conductor cable, which has the module number O-57375-. The faceplate is also home to a female connector socket. On the back of the O-57419- Input Module, you will find two edge connectors that are used to attach the module to the system backplane.
