MACH-ProZone™
BACnet® Controller

Small, durable and packed with flexibility, the Reliable Controls® MACH-ProZone™ is a fully programmable BACnet® Building Controller (B-BC) with highly scalable I/O in a very small footprint. The MACH-ProZone is ideal for a wide range of applications that include small to mid-sized roof top and heat pump applications, and small mechanical room applications. The controller features up to 8 universal inputs and up to 8 universal outputs with jumper selectable relay configuration. The MACH-ProZone ships standard with removable terminal blocks and support for 8 SMART devices.

Typical Object Configuration
There are physical limitations to the number of inputs, outputs, and SMART-Sensors that can be connected to a MACH-ProZone controller. For other object types, a maximum number of 128 objects of a single type can be created. The total number of objects (including inputs, outputs, and SMART-Sensors) is limited to 160, and is also limited by the onboard memory. The table below details typical databases that fit in all models.
