SECU-DATA 500M
SECU-DATA 500C / 1500C
Functionality:
The status of the relay contacts Re1 and Re2 connected to the inputs of the
SECU-DATA 500M, is detected and sent per RF-connection to the receiver
module SECU-DATA 500C / 1500C.
Note: There is a current limited voltage present on the inputs for testing the
relay contact status. Therefore the contacts have to be potential free and
insulated, terminals 4 and 6 are internally connected within the SECU-
DATA 500M. The contact statu
relay contact status. Therefore the contacts have to be potential free and
insulated, terminals 4 and 6 are internally connected within the SECU-
DATA 500M. The contact statu
s (“open“ or “closed“) is reproduced on the
relay outputs Re1 and Re2 on the SECU-DATA 500C / 1500C. The contact
function, make or break, can be configured. The rated switching capacity is
30 V / 500 mA.
Important application note: SECU-DATA maintains the last valid value on
the receiver outputs in case of connection problems. To ensure that the
connected controlled device is turned off (very important for overfill preven-
tion systems!) the make contact of relay Re1 has to be connected in series
to the „RF-status“ contact (blue line in the connection diagram).
