Product Description:

The model S20-DOR-4/2-220-AC is a Four Channel Relay Output Module built for efficient switching in industrial automation systems. It comes in a gray housing and weighs approximately 206 grams. It is designed for flexible mounting positions and meets IP20 protection standards.

This S20-DOR-4/2-220-AC relay module from Bosch Rexroth operates reliably in environments with a contamination degree of 2 and supports overvoltage categories II and

depending on altitude. This module connects using push in technology and is compatible with conductor sizes ranging from 0.2 mm^2 to 1.5 mm^2 or AWG 24 to 16. The required stripping length is 8 mm. The relay output system uses 2 wire connectivity. It operates with a nominal output voltage of 220 V DC or 230 V AC and supports a wide voltage range from 24 V to 220 V DC and 24 V to 230 V AC. The voltage tolerances are - 20 % to + 15 % with AC frequencies of 50/60 Hz. Each channel can handle up to 8 A of current while the entire module can handle a combined current of up to 32 A. The local bus interface connects via a bus base module and supports a transmission speed of 100 MBit/s. This ensures fast and efficient communication with other modules within the automation system.

The S20-DOR-4/2-220-AC relay module uses a 5 V DC UBus supply for logic operations. The maximum current drawn from the UBus is 280 mA with a maximum power consumption of 1.4 W. These values support low power logic operations while maintaining stable performance across extended periods. This relay module's build supports high electrical endurance and reliable operation in standard industrial applications.
