1. Introduction
The M-7026 is a Modbus RTU based multifunction module with 6 analog inputs, 2
analog outputs, 3 digital inputs, and 3 digital outputs . It provides a programmable input
range on all analog inputs (+/-150 mV, +/-500 mV, +/-1 V, +/-5 V, +/-10 V, +/-20 mA or 0
~ +20 mA). The analog outputs are 12-bit at +/-5 V, +/-10 V, 0 ~ +20 mA or +4 ~ +20
mA. All digital outputs can be set as alarm outputs. Each analog input can be
configured for an individual range and provides a high overvoltage protection of 240
Vrms. Voltage and current inputs/outputs are jumper selectable.

5. Configuration
To install the module, follow the steps below:
1. Connect the thermistor analog input.
2. Connect the module to the RS-485 network using the DATA+ and DATA- terminals. If
the host is only equipped with an RS-232 interface, then an RS-232 to RS-485
converter will be required.
3. Connect the module to the power supply using the +Vs and GND terminals. Note that
the voltage supplied should be in the range of +10 to +30V DC.

7. For M-7000 modules using the Modbus RTU protocol, configure the module using the
following functions.
・ Sub-function 04h of Function 46h, see user manual Section 3.3.2
・ Sub-function 06h of Function 46h, see user manual Section 3.3.4
・ Sub-function 08h of Function 46h, see user manual Section 3.3.6
For M-7000 modules using the Modbus RTU protocol, use Function 04h to read the
data from the input channels. See user manual Section 3.2 for details.
