Modbus and CANbus to Analog IO wiring diagram
What is the MCM260X-5AD?

The MCM260X-5AD is a compact analog I/O converter that bridges sensors to Modbus or CANopen networks. It provides four analog input channels and two analog outputs in a DIN rail–mounted module.

How many analog inputs does it have and what signals are supported?

The module has 4 analog inputs selectable for thermocouples, RTDs, thermistors, current (0–20 mA, 4–20 mA,), voltage (0–1 V, 0–5 V, 0–10 V, 0-60mV), and potentiometers.

Which thermocouple and RTD types are supported?

Supported thermocouples include K, J, S, and R. Supported RTDs include Pt100, Pt500, Pt1000, and Ni100K. Thermistor types include NTC and PTC.

What analog output options are available?

The MCM260X-5AD provides 2 analog outputs selectable between 4–20 mA and 0–10 V for retransmission or control.

Which communication protocols and speeds are supported?

The device operates as a Modbus slave (up to 57,600 baud) or as a CANopen device (up to 1 Mbit/s).

How do I switch between Modbus and CANopen?

Protocol selection is performed via on-board DIP switches—no special tools are required. You can purchase for one protocol and later switch if needed.

How is the MCM260X-5AD installed?

The unit is small in size and designed for standard DIN rail mounting, enabling high-density panel installations.

Where is the MCM260X-5AD typically used?

Common applications include PLC/SCADA expansions, mixed-signal acquisition and retransmission, and systems requiring protocol flexibility between Modbus and CANopen.
