This document assumes the reader is familiar with the SAE J1939 standard.
Terminology from the standard is used but is not described in this document.
NOTE: When a description is in “double-quotes” and bolded, this refers to the name of
a user configurable setpoint (variable). If it is in ‘single-quotes’ and italicized, it refers to
an option for the associated setpoint.
For example: “Output Type” set to ‘Analog Current’
This product uses the Axiomatic Electronic Assistant to program the setpoints for
application specific requirements. After configuration, the setpoints can be saved in a file
which could then be flashed into other AX1307x0 controllers over the CAN network.

1. OVERVIEW OF CONTROLLER
1.1. Description of CAN to 2 Analog/Digital Signals and 1 Relay Output Converter
This User Manual describes the architecture and functionality of the CAN to 1 Relay and 2 Analog
Outputs Converter (CAN-1RLY-2AOUT). It accepts power supply voltages from 9 to 36 VDC. All
logical function blocks on the unit are inherently independent from one another but can be configured
to interact with each other. All parameters are configurable using Electronic Assistant.
This controller is designed for versatile control of CAN bus to 2 analog/digital outputs and a relay
output. The hardware design allows for the controller to have a wide range of output types. The
control algorithms/function blocks allow the user to configure the controller for a wide range of
applications without the need for custom firmware. The various function blocks supported by this
controller are outlined in the following sections.
The normally open/normally closed relay output can be configured to respond in different types:
Normal Logic, Inverse Logic, Latched Logic, Inverse Latched Logic and Toggle Logic. The relay
outputs are described in more details in section 1.2.
Similarly, the analog output can be configured to different types: Analog Current, Analog Voltage,
Digital PWM, Digital Frequency and Digital ON/OFF. The analog output is described in more details
in section 1.3.

User Manual UMAX1307x0. Version: 2B 7-61
1.2. Relay Output Function Block
The following sub-sections will explain in more detail the functionalities and available
setpoints/parameters.
1.2.1. Relay Output Functionality
The relay output has 2 states: Normally Open and Normally Closed. It has 3 pins associated with it:
Normally Closed (NC), Normally Open (NO), and Common (C). The “Relay Output Type”
parameter allows for flexibility in the response of the output. Table 1 shows the options available
for this parameter.

Table 1: Relay Output Types
By default, ‘Normal Logic’ response is used for the relay outputs. In ‘Normal Logic’ response, the
Common pin is connected to the Normally Closed pin if the source of the respective relay output is
triggered ON, the Common pin is connected to the Normally Open pin.
In the case of ‘Inverse Logic’ response, the Common pin is connected to the Normally Open pin
when the source of the respective relay output is triggered ON. When the source of the respective
relay output is triggered OFF, the Common pin is connected to the Normally Closed pin.
In the case of ‘Latched Logic’ response, the Common pin is toggled between Normally Closed and
Normally Open pins every time the source of the respective relay output goes from OFF to ON.
The ‘Inverse Latched Logic’ response will respond the opposite way.
The ‘Toggle Logic’ lets the relay output toggle between Normally closed and Normally Open pins
for a configured frequency. The time for switching from one state to the other state results the
“Relay Blink Rate” which is in milliseconds and by default 500ms.
1.2.2. Relay Output Control / Enable Sources / Override Source
The relay output can be configured to be commanded and/or enabled by the control sources
listed in Table 2. This table also displays the number associated to the control sources which can
be selected. The default control source is highlighted while the default Enable Source
and Override Source is configured to ‘Control Not Used’.

Table 2: Control Sources
The selected control source in the “Relay Control Source” parameter is the main commanding
source of the relay output based on “Relay Output Type” parameter. A delay can be set for both
output states when “Relay Enable Response Delay” is set to be ‘TRUE’. In case the output state
should turn low after a certain amount of time, the parameter “Relay Delay OFF Time” can be set.
Whereas the “Relay Delay ON Time” can be configured to set a delay before switching from the
OFF-state to ON-state. Both delays are configurable in milliseconds.
1.2.3. Relay Output Enable
The “Relay Enable Source” will determine whether or not the relay output will be commanded by
the “Relay Control Source”. There are six different “Relay Enable Response” in which the
enable signal can be used. These responses are listed in Table 3.
Value
Meaning
0 Enable When ON
1 Enable When OFF
2 Disable When ON
3 Disable When OFF
4 Enable When ON Else Keep State
5 Enable When OFF Else Keep State
Table 3: Relay Enable Response
When the “Relay Enable Response” is set to ‘Enable When ON’ or ‘Disable When OFF’, the
relay output will be commanded according to the combined signal of the “Relay Control Source”
and “Relay Control Number” only when the signal of the “Relay Enable Source” and “Relay
Enable Number” is ON. Otherwise, the relay output is commanded to the OFF state.
Similarly, when the “Relay Enable Response” is set to ‘Enable When OFF’ or ‘Disable When
ON’, the relay output will be commanded according to the “Relay Control Source” and “Relay
Control Number” only when the signal of the “Relay Enable Source” and “Relay Enable
Number” is OFF. Otherwise, the relay output is commanded to the OFF state.

User Manual UMAX1307x0. Version: 2B 9-61
In case the “Relay Enable Response” is ‘Enable When ON Else Keep State’, the relay output will
be commanded according to the signal of the “Relay Control Source” and “Relay Control
Number” only when the signal of the “Relay Enable Source” and “Relay Enable Number” is
ON. If the Enable Signal is OFF, the relay output will keep the previous state.
Likewise, when the “Relay Enable Response” is configured to ‘Enable When OFF Else Keep
State’, the relay output will be commanded according to the “Relay Control Source” and “Relay
Control Number” only when the combined signal of “Relay Enable Source” and “Relay Enable
Number” is OFF. Otherwise, the relay output holds the previous state.
1.2.4. Relay Output Override
The “Relay Override Source” will determine whether or not the relay output will be commanded
by the “Relay Control Source”. This Source has a higher priority than the Enable Source.
There are two different “Relay Override Response” in which the Override signal can be used.
These responses are listed in Table 4.
Value
Meaning
0
Override When
OFF
1
Override When ON
Table 4: Relay Override Response Options
When the “Relay Override Response” is configured to ‘Override When ON’, the relay output will
be commanded according to the signal of the “Relay Control Source” and “Relay Control
Number” by the “Relay Override State” only when the override signal is ON. If the “Relay
Override Response” is set to ‘Override When OFF’, the relay output will be commanded only
according to the signal of the Control Source/Number by the “Relay Override State” only when
the override signal is OFF. Table 5 shows the two possible states for the “Relay Override State”.
In case of ‘Override State OFF’, the relay output switches to Normally Open. If ‘Override State ON’
is configured, the relay output changes to Normally closed.
Value
Meaning
0
Override State OFF
1
Override State ON
Table 5: Relay Override State Options
1.2.5. Unlatch Source
This Source can only be configured if the “Relay Output Type” is set to ‘Latched Logic or ‘Inverse
Latched Logic’ and it can be enabled/disabled by the parameter “Relay Enable Unlatch Source”.
If the signal of the “Relay Unlatch Source” is ON, it turns the output OFF when the “Relay
Output Type” is set to ‘Latched Logic’. If the Unlatch Source state turns OFF afterwards, the
output state stays OFF independent of the output state before. The reverse behavior is applied to
the Inverse Latched Logic.

User Manual UMAX1307x0. Version: 2B 10-61
1.3. Analog Output Function Block
The controller has 2 analog/digital outputs can be configured and they are inherently independent
of each other. The Analog Output Type parameter determines what kind of signal the output
produces. Changing this parameter will update other parameters in the group to match the
selected type. For this reason, it should be the first parameter to be changed. The supported
output types by the controller are listed in Table 5 below:
Value
Meaning
0

2
Analog Voltage
3
Digital PWM
4

Frequency
5

Table 6: Analog Output Type Options
The control signal of the outputs will have associated with it a minimum and maximum values.
Besides type Digital ON/OFF, all the other output types are always responding in a linear fashion
to changes in the control source per the calculation in Figure 1.

Figure 1 - Linear Slope Calculations
X and Y are defined as:
Xmin = Control Input Minimum Ymin = “Output At Minimum Command”
Xmax = Control Input Maximum Ymax = “Output At Maximum Command”
In all cases, while the X-axis has the constraint that Xmin < Xmax, there is no such limitation on the
Y-axis. This allows for a negative slope so that as the control input signal increases, the target output
value decreases. Or it allows output to follow control signal inversely.
The “Fixed Frequency/Duty Cycle” is set to 500.0 [Hz] by default for all the output types except
for ‘Digital Frequency’, the value is set to a default value as 50.0 [%Duty Cycle]. Since both outputs
are connected to independent timers, this parameter can be changed at any time for each output
without affecting the other.
