6.2.3 Module RS-232 with two relay outputs
The optional module RS-232 with two relay outputs allows the connection of the integrator Super-
cal 531 to a control system, a system processor, a modem or a PC.
Thus, it is possible to readout the data of the heat meter and to transmit them via RS-232 inter-
faces.
The module RS-232 with two relay outputs combines the advantages of the communication with a
control system (or any other controllers and remote readout systems) over RS-232 with the trans-
mission of status messages, alarm and/or errors as relay output.
The communication is based on the M-Bus protocol acc. to EN 1434-3 and IEC 870-5.
The transmission rates are freely selectable between 300 and 38'400 baud. The readout can be
done with a M-Bus read-out software. If equipped with a module RS-232 with two relay outputs, the
Supercal 531 must always be mains voltage supplied.
Each relay output is galvanically isolated and features two switching contacts.
6.2.4 Module RS-232
Application identical to point 6.2.3
The module RS-232 features the advantages of the communication over RS-232 with a control
system or any kind of controllers, control or remote readout systems.
The communication is based on the M-Bus protocol in accordance with EN 1434-3 and IEC 870-5.
The transmission rates are freely selectable between 300 and 9'600 baud. The readout can be
done with a M-Bus readout-software. In case of continuous communication of more than once a
day, we always recommend mains voltage supply.
