Product Description:

This RL40-112-00000-U00 fieldbus coupler from Danaher supports the PROFIBUS DP protocol. The coupler serves as a communication gateway for automation infrastructure. This product enables data acquisition with high accuracy. The device also delivers independent supervision, monitoring, and control in a decentralized automation installation. This unit is used along with the manufacturer’s Rail Line I/O extension module. Its standard 22.5 mm width ensures that it is compact in size. The coupler can be fitted onto a top-hat DIN Rail.

This product is fixed to the DIN rail using spring-clamp connectors or plug-in screw terminals. The device always comprises the data for transmission. This unit and the corresponding I/O modules are connected by an internal bus. It supports float and integer data formats. The coupler uses a twisted two-wire, screened cable as its transfer medium. This product portrays communication according to the master/slave principle. The device meets 89/336/EEC European guidelines. The unit should always be mounted in the supporting enclosure for operation. It should be provided with a power switch or a circuit breaker.

The coupler’s supply voltage must comply with the specification on its type label. This product’s housing contains ventilation slots that should not be covered. The device’s measurement inputs support transient voltage peaks of up to 800 V against the protective earth. This unit needs minimal or no maintenance when it is used properly. Its maintenance and modification are allowed only by skilled personnel. The fieldbus coupler may have exposed electrostatically sensitive or live parts if it is opened. This product’s faulty or improper connection can lead to its destruction. The device delivers no support for installation in explosion-hazardous areas. This unit can energize a maximum of 16 function modules. It doesn’t support a cascade connection for the power supply.
