The IFM DP3603 is a two-channel field relay adapter with normally open outputs designed for reliable switching in industrial automation applications. It provides electrical separation between input and output circuits and uses M12 connection technology for practical field installation. Its IP69K protection makes it suitable for demanding environments, while semiconductor relay technology enables durable, bounce-free switching.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The DP3603 provides a convenient way to install relay switching functions directly in the field rather than routing every switching signal back to a control cabinet. It features two digital inputs and two relay outputs with normally open functionality. This makes it useful where higher-current switching or electrical separation is required near the machine.
The unit uses two semiconductor relay channels for switching external loads. The outputs are electrically separated from the input side, allowing an input control signal to switch an independent output voltage. The relay outputs are normally open, making the module suitable for controlled switching applications in industrial equipment.
M12 connection technology allows the DP3603 to be installed close to sensors, actuators and other machine components. This can reduce control-cabinet wiring and simplify installation. Its compact construction supports decentralised automation architectures where switching functions are distributed throughout the machine.
The DP3603 is designed for harsh industrial environments and provides IP67 and IP69K protection. According to IFM technical data, it operates from 18...30 V DC, with 24 V DC nominal voltage, and supports two digital inputs and two relay outputs. Each output supports up to 1000 mA under specified conditions.
