What does this optocoupler interface module do?
It provides galvanic isolation between a mains AC control signal on the input side and a low-voltage DC switching output on the load side, using an optocoupler and a transistor output stage. This helps separate high-voltage control circuits from 5–48 VDC control loads.
What input voltage range is required to switch it on?
The input switches ON in the range 90…250 VAC. Below this it will not reliably switch on.
What input voltage range is considered off?
The input is specified OFF at 0…40 VAC, which helps avoid unintended switching at low AC voltages.
How much current does the input side draw?
The control current is specified as 7 mA on the input side.
What type of output does it provide?
It provides a transistor DC output designed for switching DC loads within a 5…48 VDC switching voltage range.
What is the maximum output current it can switch?
The switching current per output is specified from 0.1 mA up to 0.5 A maximum.
What is the output leakage current when it is off?
With the output open (off state), leakage current is specified at a maximum of 0.3 mA. For very small loads, this leakage may be noticeable, so verify the load’s off-state requirements.
What is the voltage drop across the output when it is on?
The saturation voltage across the output is specified as a maximum of 1.2 VDC, which can be used to estimate the voltage available to the load at the chosen current.
How fast does it switch on and off?
Typical switching times are 55 ms ON and 15 ms OFF, making it suitable for many control and signalling tasks rather than high-speed switching.
What switching frequency can it handle?
Maximum switching frequency is specified as up to 500 Hz for resistive loads and up to 30 Hz for inductive loads.
Is there electrical isolation between input and output?
Yes. The module’s test isolation voltage is specified as 3.75 kV, providing strong separation between the AC input and DC output circuits.
How is it mounted in a control cabinet?
It is DIN-rail mountable in accordance with EN 60715, allowing quick installation alongside other control components.
What terminal type does it use for wiring?
It uses spring clamp terminals, which are designed for fast, reliable connections without screw tightening.
Does it have a status indicator?
Yes. A yellow LED display indicates the switching status.
What are the operating temperature limits?
The specified operating temperature range is -20…+60 °C.
How much space does it take on the DIN rail?
Its dimensions are 78 × 6.2 × 70 mm (H × W × D). The 6.2 mm width makes it suitable for high-density cabinet layouts.
Can it be used to interface a 230 VAC signal to a 24 VDC load?
Yes, that is a common use case: a mains AC input (within 90…250 VAC) can switch a DC load powered at 24 VDC, provided the load current remains within the 0.5 A maximum and the application tolerates the specified switching times and leakage current.
What housing material is used?
It is supplied in a black, flame-retardant plastic housing.
Is this a single-channel module?
It is specified as a single optocoupler interface module with one input and one transistor output (commonly referenced by the article 6652507 in documentation).
- Converting a high-voltage AC control signal (90–250 VAC) into a low-voltage DC switching output (5–48 VDC) for interfacing between field devices and control circuits
- Providing galvanic isolation between mains-voltage inputs and sensitive DC loads to help reduce the impact of electrical noise and transients
- Switching DC loads up to 0.5 A from an AC control source in panel-based automation systems
- Retrofitting legacy 230 VAC control outputs to operate modern 24 VDC input devices without redesigning the upstream control wiring
- Implementing compact, DIN-rail mounted signal conversion where space is limited (6.2 mm width)
- Isolating and adapting AC status signals from contactors, relays, or auxiliary contacts to feed DC monitoring and indication circuits
- Creating an optically isolated interface for splitting and conditioning control signals across different voltage domains within a cabinet
- Adding visual status indication of input state via the built-in LED for quick panel diagnostics and commissioning checks
- Switching resistive and inductive DC loads at practical industrial frequencies where solid-state switching is preferred over mechanical contacts
- Building modular I/O or marshalling arrangements using spring-clamp terminals for fast, tool-efficient wiring in control panels
