The ValuePoint-M module consists of a Main Board (processor, network interface, power supply, I/O) and an optional I/O expansion board
connected to the Main Board by a ribbon cable. The Main Board only supports a single expansion board. The only type of expansion board
available is the ValuePoint DOX, which provides 4 additional relay outputs.
The ValuePoint-M includes the following I/O points:
•

•
•
12 Analog Inputs (Universal Inputs – 0-10 vdc, 4-20ma, Type 3 10kThermistor, Dry Contact)
2 Analog Outputs (0-20ma, 0-10 vdc)
2 Isolated Digital Inputs
4 Dry Contact Form A relays (expandable to 8)
12/24 vdc (jumper selectable) sensor excitation supply (J7)

ValuePoint-M Product Data (Revision A)
2.0 – Operation
2.1 – Inputs
The 12 analog (or universal) inputs may be configured to sense 0-10 vdc, voltage levels, 4-20 mA current levels, 10k Type 3 thermistors or dry
contact closures. The a/d converter is a v/f converter with at least 12 bits of resolution.
The 2 digital inputs are designed for 24 volt signals, either AC or DC. These inputs use are optically isolated from the rest of the system. These
input channels are not isolated from each other.
2.2 – Outputs
The 2 analog outputs may be independently configured for 0-10 vdc or 4-20 mA outputs using jumper settings. Additionally, moving a jumper
allows the channel to be manually controlled by an onboard potentiometer. Resolution is 8 bits.
The 4 digital outputs are Form A dry contact relays rated for up to 10 amps (resistive). Hand-Off-Auto (HOA) switches allow overriding the
system and manually controlling the relays. The common side of all relay contacts are electrically common to each other. Therefore, the
outputs are not isolated from each other.
2.3 – Service Button / Service LED
The service button found on the ValuePoint-M is used in the installation process to cause the node to transmit its ID. This service button
conforms to all LonWorks standards for implementation of the service button.
The green LED closest to the bottom edge of the board is the service LED. This LED will light any time the service push button is pressed. In
addition, this LED will activate upon power-up of the module.
Upon power-up, the service LED may indicate any of several conditions and serves as a diagnostic tool. Normally, the service LED should flash
only once, then turn off upon power-up. If the LED never lights, stays on indefinitely, or flashes indefinitely, it may indicate a hardware or
software problem.
2.4 – Status LED
The status LED is the green LED just above the service LED at the bottom of the board. The status LED will flash when a KPS Open-3 API
application is running.
2.5 – System Reset
The ValuePoint-M node may be reset by cycling power to the unit or by sending a reset network management command. In either case, the
service and status LED’s will flash as noted above, and all node hardware will be reinitialized (outputs turned off, etc…).

3.4 – Excitation Voltage Selection (J7)
The Excitation voltage output can typically source 100 mA of power at 24 vdc or 200 mA at 12 vdc. Jumper J7 selects whether the excitation is
12 or 24 vdc. Install J7 to select 12 vdc, remove J7 to select 24 vdc.
Note: In order to source 24 vdc the power input must be 27-30 vdc or 24 vac.

4.0 – Connections
4.1 – Field Wiring
The wire terminal blocks on the ValuePoint-M will accommodate solid or stranded wire from 24 gauge down to 14 gauge. Wires should be
stripped at the ends with approximately ¼” (7mm) of bare wire to be inserted into the terminal block.
Wires are attached by inserting the bare end into the terminal and tightening the respective screw with a small screw driver.
4.2 – Network Wiring
The ValuePoint-M uses the Echelon FTT-10A transceiver in each module. These transceivers offer advantages over other technologies,
allowing substantial freedom in the wiring scheme used.
Best results are obtained when specified wire types are used for network communications. The Echelon FTT-10A Transceiver User’s Guide
should be consulted for full details on wire recommendations.
The FTT-10 network requires termination for proper data transmission. A total termination impedance of ~52Ω is needed.
In a free topology network, only one termination is required and may be placed anywhere on the network. The termination should consist of a
single 52.3Ω 1% resistor.
In a doubly terminated buss topology, two terminations are required -- one at each end of the network. Each termination should consist of a
105Ω 1% resistor.
To install the termination, connect the resistor of the proper value across the network terminals of any LonWorks node on the network for free
topology, or across the network terminals of the two nodes that are physically at the ends of the network for doubly terminated buss topology.
Insert the wire leads of the resistor into the terminal block along with the network cable and tighten the terminal screw.
4.3 – Power Supply
The miniature switching power supply found in each ValuePoint-M is designed to operate from a wide range of input values. Either AC or DC
power may be used. If DC power is used, the polarity of the connection must be observed. Reverse polarity DC will not damage the module,
but it will not operate the module either.
The ValuePoint-M will operate on 10-30 vdc or 24 vac.
Minimum Input: 10 vdc regulated, 15 vdc unregulated, 20 vac
Maximum Input: 40 vdc regulated, 25 vdc unregulated, 28 vac

used to select 0-10 vdc input. The “I” position is used to select 4-20 mA input. The “T” position is used to select 10k Type 3 Thermistor, or dry
contact sensing.

4.6 – Digital Inputs
4.6.1 - Configuration Jumper (J5)
Digital input type selection simply determines whether a filter capacitor is applied to the isolated side of the input to slow response. If the input
signal is AC or DC with some noise, select the AC position to add filtering. If the application intends to use these inputs in a pulse counting
manner, the DC position should be used. The left two pins jumpered vertically (J5-L) configure digital input #1 and the right two pins jumpered
vertically (J5-R) configure digital input #2.

4.8.2 – Manual Control of Analog Outputs
Selection of manual override requires moving a jumper (one per channel) as illustrated in the previous section regarding jumper positions
(Selection of Analog Output Type).
Once placed in manual override, the potentiometers near the configuration jumper header may be used to control the analog outputs. The
following diagram illustrates the manual override controls.

Note: The outputs will manually range from 0-10 vdc in voltage output mode. However, in current output mode, outputs will range from 0-20
mA. The standard 4-20 mA output requires that the software properly scale data and apply an offset to the DAC. Since this offset is a function
of software, the offset will not be present in manual override, and thus the output will actually be 0-20 mA in manual override.
