TM5SDO4T Modicon TM5 Digital Output Module 4DO 24V DC 0.5A

The TM5SDO4T is a Modicon TM5 digital output module with four protected 24 V DC transistor outputs.

Each channel can switch up to 0.5 A, with a maximum combined output current of 2 A. It is suitable for indicator lamps, interface relays, small solenoid valves and other low-current DC loads.

The module provides fast 300-microsecond switching together with short-circuit, overload and thermal protection. After the fault is removed, the affected output can reset automatically.

Unlike the TM5SDO4TA, this model is intended for lower-current loads rather than 2 A actuators.

Key Features

• Four 24 V DC transistor outputs
• 0.5 A maximum per channel
• 2 A maximum total current
• 300-microsecond switching
• Short-circuit and overload protection
• Thermal protection
• Automatic fault reset
• Reverse-polarity protection

Typical Applications

• Indicator lamps
• Interface relays
• Small solenoid valves
• Contactor interface circuits
• Packaging machinery

Output Current Limits

Maximum per Channel

0.5 A

Maximum for Four Channels

2 A

The total current of all active outputs must remain within the 2 A module limit.

Protected Transistor Outputs

The module includes electronic protection against:

• Short circuit
• Excessive load current
• Internal overheating
• Reverse supply polarity

Repeated fault resetting indicates a wiring or load problem that must be corrected.
