1. Introduction
The M-7018Z is a 10-channel universal Analog Input module with an RS-485 interface
that is especially designed for extremely accurate thermocouple measurement and
features automatic cold-junction compensation for each channel to ensure temperature
output consistency and stable temperature output in the field. The innovative design of
the enhanced model ensures that thermocouple measurement is more accurate than
with the earlier design. Besides the thermocouple inputs, the M-7018Z also supports
voltage and current input. The voltage input range can be from +/-15 mV to +/-2.5 V. Up
to 10 different types of Analog Input can be connected to a single module. Overvoltage
protection of up to 240 Vrms is provided. The module also features per-channel open
wire detection for the thermocouple and +4 ~ +20 mA input channels. The M-7018Z
provides additional support for both the Modbus RTU and DCON protocols, which can
be configured via software.

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.
