PS-6244 Description
Controller & Keypad
PS-6244 Series Programmable Limit Switches consist of two main components: the
controller and the keypad/display. The controller houses the microprocessor, associat-
ed circuitry, and all of the I/O circuits. This eliminates the need for external I/O racks.
A separate 1/4 DIN keypad/display provides a complete user interface from which ev-
ery aspect of the controller’s operation can be monitored and programmed. Multiple
keypads can be connected to a single controller. In addition, when interfaced to a PLC
or other computer, the controller can be used without a keypad/display. When properly
mounted with the gasket provided, the keypad/display meets NEMA 4X standards. A
clear silicon rubber boot assembly is available to provide protection for installations
where harsh washdown chemicals are used.
The PS-6244 Series is available in two models: the PS-6244-24-M17 and the PS-6244-
24-X16M09 Both are described in Figure 3.
Figure 3—PS-6244 Models
PS-6244-24-N16M09 Controller—Up to 25 Outputs
PS-6244-24-M17 Controller—Up to 17 Outputs
The PS-6244-24-M17 has 17 total outputs:
• Outputs 1 through 15 can accept AC or DC output
modules for driving “real world” devices such as
solenoids, valves, or glue guns.
• Output 16 will accept an AC or DC module, or an
analog module that generates a control signal
proportional to RPM.
• Output 17 is dedicated to analog output.
The PS-6244-24-N16M09 has 25 total outputs:
• 16 transistor outputs are built into the controller.
• Outputs 17 through 23 can accept AC or DC output
modules for driving “real world” devices such as
solenoids, valves, or glue guns.
• Output 24 will accept an AC or DC module, or an
analog module that generates a control signal
proportional to RPM.
• Output 25 is dedicated to analog output.
