The outputs of the modules TSX DSY 08R5 and TSX DSY 16R5 do not feature any contact protection; it is therefore necessary to take the following precautions.
These relay outputs feature no protective measures, in order to make it possible to control the following:
-
galvanic insulated inputs - at low energy level and requiring zero leakage current,
-
power circuits, whilst eliminating inductive over-voltages at the source.
It is therefore obligatory to mount the following on the pre-actuator coil terminals:
-
an RC circuit or a MOV (ZNO) peak limiter for use with alternating current,
-
a discharge diode for use with direct current.
NOTE: a relay output that has been used with an alternating current load must not be then used with direct current, and vice versa.
