15 Product description
2.1.7 TC/TS connector
N. 10 Rear panel (DB25 type - female)
Signals compatible with standard IEC 60864-1.
As reported here applies both to the signals TC/TS that for the signals PROFILES.
• Digital I/O
• Polarity N
• Maximum voltage range: 0 to +30 V
• Operating voltage: b0.5 and +5 .. +24 V
• Input Current : 5mA (controlled in parallel)
• Output current : 50mA max. Of the open drain type, can be connected in parallel
(or wired, with the exception of the fault signal that is reversed polarity). Can drive
inductive loads, in which case it is recommended to clamp diode in parallel with
the load (cathode power supply).
• The inputs are supplied on board (pull up = 1 kOhm, +5 V) with EMI filter series and
diode. This allows the command in parallel. Are considered active when they are
shorted to ground (active between 0 and +0.5 V). Are considered inactive if open or
input voltage> = +4 V. Some are for command to state, for other command pulse,
the pulse duration must be> = 0.5 seconds.
• The output signal is active (mos) with the circuit breaker closed. One exception is
the default output, which is reversed polarity to ensure the signaling in the absence
of power. The parallel connection of multiple fault lines does not cause electrical
problems, but the primary message is meaningless.
• The analog outputs are between 0 and +4.5 V, Z = 470 ohms. Are protected against
short circuit to ground or the voltage fed up to a maximum of +5 V.
