Johnson Controls M4-XPM series I/O expansion modules

XPM Series Expansion Modules

The M4-XPM series I/O expansion modules can serve

in one of two capacities depending on where they are

installed in the Metasys system. When installed on

the Sensor/Actuator (SA) Bus of a Metasys equipment

controller, an XPM expands the input and output

interfaces that can be used with that equipment

controller. When installed on the Field Controller (FC) Bus

of a Metasys network engine, an XPM can be used as I/O

point multiplexors to support monitoring and control from

a Metasys network engine. The point multiplexor can also

be useful for sharing points between other equipment

controllers on the FC Bus using peer-to-peer connectivity.

Features and benefits

Sleek and modern packaging and styling

Provides a modern, aesthetically pleasing industrial

design.

Standard hardware and software platform

Uses a common hardware design throughout the

family line to support standardized wiring practices and

installation workflows. Also uses a common software

design to support use of a single tool for control

applications, commissioning, and troubleshooting to

minimize technical training.

High memory capacity and fast processing power

Provides application engineers with the horsepower to

meet sophisticated control requirements.

Auto-Tuned Control Loops

Reduce commissioning time, eliminate change-of

season re-commissioning, and reduce wear and tear on

mechanical devices.

Patented Proportional Adaptive Control (P-Adaptive)

and PRAC

Provides continuous loop tuning.

Standard BACnet protocol

Provides interoperability with other Building Automation

System (BAS) products that use the widely accepted

BACnet standard.

Models to support both BACnet MS/TP and N2. with

auto-detection of the communications protocols

Controller auto-detects the BACnet MS/TP or N2 protocol

that is connected to it, which enables the same controller

to support multiple communication protocols without

the need to purchase a special model per protocol, and

without extra manual setup.

BACnet Testing Laboratories (BTL) listed and certified

Ensures openness and interoperability with other BTL

listed devices. BTL is a third-party agency, which validates

that BAS vendor products meet the BACnet industry

standard protocol.

BACnet automatic discovery

Supports easy controller integration into a Metasys BAS.

Wireless ZFR and ZFR Pro support

Provides a wireless alternative to hard-wired MS/TP

networking, offering application flexibility and mobility

with minimal disruption to building occupants, and also

simplifies and speeds up replacements.

Integral real-time clock

An integral real-time clock, which enables the controllers

to monitor and control schedules, calendars, and trends,

and operate for extended periods of time as stand-alone

controllers when offline from the Metasys system network.

Pluggable screw terminal blocks

Pluggable input/output wiring terminal blocks provide

electrical installers and field technicians the ability to

quickly and easily install and service a controller without

the need to disconnect and reconnect the input/output

wiring.

Decimal MS/TP address set with three rotary switches

Easy-to-use rotary switches set the MS/TP address in

decimal format.

Universal Inputs and Configurable Outputs

Allows multiple signal options to provide input/output

flexibility.

End-of-Line (EOL) switch in MS/TP devices

Enables equipment controllers and I/O expansion

modules to be terminating devices on the

communications bus.

Default state for equipment controller Input/Output

wiring validation

Enables validation of the input and output terminals’

wiring prior to download of an application file.

Background transfer coupled with enable/disable logic

options in Controller Configuration Tool (CCT)

Saves field technicians’ time, enables productivity and

minimizes equipment disruption, since the controllers are

operating while file updates take place in the background

and the application can be left disabled until the system is

ready to run.

SA Bus commissioning improvements

Saves field technicians time when commissioning SA Bus

devices by enabling an equipment controller to transfer

and apply firmware files to all the SA Bus devices (XPM,

IOM, NS8000) connected to it at the same time.
