With a wide range of connectivityoptions, a lot of protection is integrated into a PLC whichin turn controls, for example, one or more safe outputs ina qualified manner without risking a dangerous situation.Using an expansion relay, such as BT50, the number ofsafe outputs in Pluto can be expanded. The connectionwill then be made as shown in the figure. If IDFIX PROG isused for single-Pluto, there is the option of copying a PLCprogram via the identification circuit over to Pluto withouthaving to connect a computer.A1X424VDCType: BT50Connection example of a contactexpansion with Pluto2:8ABB
