MACH-ProPoint Input Expansion Module MACH-ProPoint Input Expansion Module Header
Maximize the monitoring capacity of any Reliable Controls® MACH-ProCom™ or MACH-ProSys™ controller with this all-input expansion module. Each MPP-I features 24 universal inputs and requires 24 VAC/VDC power. MPP-I expansion modules can be mixed with standard MPP expansion modules in any combination on a single I/O-Net trunk. A maximum of 8 expansion modules can be connected to a single MACH-ProCom™. Up to 7 expansion modules can be added to the MACH-ProSys™ controller. Each controller can support a maximum total of 160 I/O points. The maximum number of inputs permitted is 128. The maximum number of outputs permitted is 64.
