Relay module for controlling of up to 8 heating cartridges
The relay module is a module for controlling up to 8 high voltage relais with 400 V for e.g. heating cartridges. Its housing is designed for saving costs while being mounted in a control cabinet. The device possesses the shortest conversion times and a high process reliability. That makes it the best choice for continuous operation in complex machine networks.
Power supply and relais
Phase L1 is only looped in. L2 and L3 are used for controlling the consumers. There is a current measurement integrated that enables a monitoring of each relay. It is build in 2 blocks with 4 relais each. A key feature of the relay module is its high process reliability. Its RP1 is a semiconductor relay for embedded board assembly with 3 regulated control currents for handling its consumers. Major advantages are both a high surge current and interference resistivity while switching AC loads.
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. The relay module is turned to 250 Kbit as a standard.
There is a powerful ARM7 micro-controller on the module for controlling the relais and the CAN protocol. Additionally, heartbeat is integrated into the device.
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.
