TM5SDO16T Modicon TM5 Digital Output Module 16DO 24V DC 0.5A

The TM5SDO16T is a Modicon TM5 digital output module with sixteen protected 24 V DC transistor outputs.

Each output can switch up to 0.5 A, while the combined current of all active channels must remain within the 8 A module limit.

Its main advantage is high output density. Sixteen low-current actuators can be controlled from one compact TM5 slice, reducing the number of output modules required in centralized machine stations.

The module includes short-circuit, overload and thermal protection, automatic fault reset and optional output monitoring.

Key Features

• Sixteen 24 V DC transistor outputs
• 0.5 A maximum per channel
• 8 A maximum total current
• Compact 1-wire output design
• 300-microsecond switching
• Short-circuit and overload protection
• Thermal protection
• Output fault monitoring

Typical Applications

• Indicator lamps
• Interface relays
• Small solenoid valves
• Pneumatic valve manifolds
• Packaging machinery

High-Density Output Control

TM5SDO16T is designed for machine sections with many low-current 24 V DC loads.

Typical uses include:

• Multiple relay coils
• Valve manifold channels
• Status indicators
• Conveyor control points
• Small pneumatic actuators

Current Limits

Maximum per Output

0.5 A

Maximum Total Module Current

8 A

All sixteen outputs may operate together only when the combined current remains within the approved total-current and temperature limits.

Protected Transistor Outputs

The module provides protection against:

• Short circuit
• Overload
• Excessive internal temperature
• Reverse polarity

After the fault is removed, the affected output can automatically reset.

Output Monitoring

Output monitoring can be enabled or disabled in software.

The monitoring function uses an approximate 10 ms delay and can report a detected output fault to the controller.

This helps identify overloaded, shorted or invalid output circuits.
