Relay module
Key Features
- Controlling up to 8 heating cartridges
- Integrated safety functions
- Small dimensions
- Simple top hat rail mounting
Description
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. The relay module is turned to 250 Kbit/s as a standard.
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.
