M8-AD Analog Input Module
4-20mA, 1-5V, 0-20mA, 0-5V
Inputs per Module 8 Channels –Common
Ground
Input Current Range 0-20mA or 4-20mA
Input Voltage Range 0-5V or 1-5V
Input Impedance 250 ohms (current mode)
Resolution 12 bits
Accuracy 0.1%
Linearity 0.1%
Supply Voltage 10-30VDC
Module Power Drain Idle 200mW
Range Selection
The analog input range options are selected via
jumpers J9 and J10, there are 3 possible options,
shown in the table below.
Note: The range selected will apply to all analog input
channels.
The factory default setting is 4-20mA / 1-5V.
Current / Voltage Selection
The analog input channels are configured by means
of J1 through J8, which correspond to the analog
channel numbers. They can be configured for any mix
of current or voltage inputs, but will all be scaled
according to the setting of jumpers J9 and J10.
Jumper settings for each channel (1 to 8)
Jumper: Channel is set to current.
No Jumper: Channel is set to voltage.
Default factory setting is jumpers (1 to 8) installed
such that all channels are configured as current
inputs.

2. Wiring Detail
The expansion modules are driven from the RS485
port on the AD2006+ module, or via an M232-485
converter if using the RS232 port of an AD2000
module.
Any combination of up to 32 expansion modules can
be driven from one AD2006+ module.
Standard RS485 parameters apply to the expansion
module bus and thus the modules do not have to be
located in close proximity to the AD2006+ but can be
can be up to 1.5km from the AD2006+ telemetry
module.
An option to run Modbus on the RS485 bus is
provided. This means that the expansion modules
can be operated in conjunction with third party
Modbus devices on a multi-drop RS485 bus.
Note: The protocol selection in MiriMap must match
the DIP switch settings on the expansion modules.
The other settings selected in software are typically:
•Interface - Expansion Modules
•Polling –Continuous
•RTS during Tx must be checked
•Baud rate - 38.4k (default)
When using an AD2000 RS232 port, you will require
an M232-485 converter connected as shown below.

3. DIP Switch Settings
The DIP Switches located at the top of each
expansion module configure the module settings.
The function of each switch is shown below.
DIP Switch Operation
Set the Baud Rate
Note: Power cycle required for change to take effect.
Set the Status Defaults
In the event of loss of communications, the digital and
analog outputs will either default to a “HOLD
LAST” or “CLEAR ALL” status according to the switch
settings below.
Select the Protocol
DEFAULT/MIRI - The default setting is Miri protocol
which would normally be used when driving only
expansion modules via RS485.
MODBUS - Modbus protocol is usually used where
other third party Modbus devices are also connected
to the RS485 Multi-Drop Network. Please note that
this can only be done at 9600 or 38400 baud, so the
third party MODBUS devices must be capable of one
of these baud rates.
Configure the Polling ID
In an RS485 Multi-Drop network, whether the
protocol is Miri or MODBUS, each Expansion Module
will need a unique ID. The DIP Switch settings above
let you do this.
