Interface RS232-SCR(IEC)
Product categories
Remote meter readout
System technology
Your benefits
- Interface converter between GWFcoder® meters and RS232 communication devices:
Easy integration into remote meter reading systems - Transparent mode of operation:
Unchanged transfer of read-out data to the communication device - Clearly marked connection terminals:
Easy on-site installation
Applications
- The interface is used for the addressed readout of water and gas meters with GWFcoder® registers via an RS232 connection
Properties
- Compatible with RS232 standard interface
- Addressed readout in accordance with IEC 62056-21 mode A
- Data transfer up to max. 150 m between GWFcoder® meter and interface
- Polarity independent connection of GWFcoder® meter to the interface
- DIN rail mounting
- The interface can be used to connect the GWFcoder® meter with SCR(IEC) interface to a communication device with an RS232 interface. The interface serves as a converter between the meter and communication device.
- The interface is mounted near to the communication device.
In combination with remote meter readout, it is possible to read out the register readings directly from a control centre via a modem. The remote meter readout software must support the GWFcoder® data set.
