Relay module for controlling up to eight heating cartridges with 400 V The relay module enables the control of eight heating cartridges with 400 V. It is designed in the open con­struc­tion typical for the Light family and impresses with its very good price-performance ratio. With its ex­treme­ly short conversion times for signal proces­sing and high process re­lia­bil­ity, this module is also ideally suited for con­ti­nuous operation in complex machine networks. Power supply and relay Phase L1 is only looped through in the relay module. The other two phases L2 and L3 are used to control the loads. Furthermore, a current measurement is integrated on the re­lay module, which enables a cyclic current meas­ure­ment of each relay. The meas­ure­ment is divided into two blocks of four relays each. The RP1 is a solid state relay for PCB mounting and has three regulated control vol­tages for the control of consumers. The high surge current capability and noise immunity there­fore make switching AC loads extremely safe. LEDs and switches Several status LEDs allow to visualise different operating modes and warning messages from its safety functions like heartbeat telegrams. Con­fi­gu­ration of the module address and baud rate can be done via HEX switches and braze jumpers. Signal processing There is a powerful ARM7 microcontroller on the module for controlling the relais and the CAN protocol. Additionally, heartbeat is in­te­gra­ted into the device. CAN interface The integrated CAN interface is designed in accordance to DS 301 and 401 for a flexible use in different places and tasks in the CAN bus network. All Sontheim CAN interfaces comply to ISO 11898.
