Output Cable Relay 2 - Signal Light - Honeywell Temaline TKL19 Installation Manual

1.5.6 Output Cable Relay 2 – Signal Light
Output Relay 2 is used for signaling the status of the door (gateway
occupied / free ) and provides both NO and NC contacts.
The external load can be powered directly from AC or DC power, in
accordance with the following limits:
Voltage Working Current
30VDC 0.5 A
30VAC 0.5 A
• Inductive load with direct current:
In this case, it is mandatory to use a repeater relay and a 1N4004 diode
in parallel to the coil for the electrical locking device in order to increase
the life of the relay inside the RTU − see Figure 12.
• Inductive load with alternating current:
In this case, it is mandatory to use a repeater relay and the MOV
(75VAC) in parallel to the coil for the electrical locking device in order to
increase the life of the relay inside the RTU see Figure 13.
• Life: assuming the relay is activated 200 times a day and that the
voltage/current limits of the preceding table are respected, the life is
guaranteed for at least 6 years; if the relay is activated less frequently,
the life of the relay increases proportionally.
• In case of excessive use (> 200 operations / day) it is suggested to use
an external relay.
