| 摘要 | To enable a safe monitoring with a small cabling effort of a modular safety relay circuit, a modular safety relay circuit for the safe control of at least one machine is provided comprising a safety relay unit that has at least one forcibly guided relay for the safe switching on and off of the machine and that generates output signals in dependence on input signals, wherein the input signals are provided by at least one connected signal transmitter and the output signals are communicated to the at least one machine; and at least one expansion relay unit for providing additional output connectors so that additional machines can be connected; wherein the expansion relay unit has at least one respective forcibly guided relay for the safe switching on and off of the machine and is monitored by means of a monitoring relay. | ||||||
