TM5SMM6D2L Modicon TM5 Mixed I/O Module 4DI 2DO 1AI 1AO

The TM5SMM6D2L is a Modicon TM5 mixed I/O module combining digital and analog signal processing in one compact slice.

It provides four 24 V DC digital inputs, two protected transistor outputs, one analog input and one analog output.

The analog input accepts ±10 V, 0–20 mA or 4–20 mA signals. The analog output can be configured for ±10 V or 0–20 mA.

Its main advantage is mixed-signal flexibility. A small machine section can connect sensors, actuators, one process transmitter and one analog control device without installing four separate I/O modules.

Key Features

• Four digital inputs
• Two transistor outputs
• One analog input
• One analog output
• Voltage and current signal support
• 12-bit analog conversion
• Protected 0.5 A outputs
• Single compact TM5 slice

Typical Applications

• Small process skids
• Packaging stations
• Proportional valve control
• Pump and fan systems
• Standalone machine units

Four Digital Inputs

The module includes four 24 V DC sink inputs for:

• Proximity sensors
• Limit switches
• Push buttons
• Relay contacts
• Machine status signals

The digital inputs provide fast hardware filtering and configurable software filtering.

Two Digital Outputs

The module includes two 24 V DC source transistor outputs.

Maximum Current per Output

0.5 A

Maximum Total Current

1 A

The outputs include:

• Short-circuit protection
• Overload protection
• Thermal protection
• Automatic fault reset
• Reverse-polarity protection

One Analog Input

The analog input can be configured for:

• -10 to +10 V DC
• 0–20 mA
• 4–20 mA

Voltage Resolution

12-Bit Plus Sign

Current Resolution

12-Bit

The selected software range must match the physical transmitter wiring.

One Analog Output

The analog output supports:

• -10 to +10 V DC
• 0–20 mA

It can control compatible devices such as:

• Variable-speed drive references
• Proportional valves
• Analog positioners
• Process setpoints

The output does not provide a separate native 4–20 mA range. A controller program may restrict the command to the 4–20 mA portion when required.
