Alarm through a QUA6 PFTU

A QUA6 PFTU can be used to connect an external alarm through normally open or normally closed contacts of one of its units. The contacts operate under the same conditions as the PFTU, and can support the capacities listed in Table 76.

Table 76

AC capacities

	AC capacities
Maximum switching power	50.0 V A.
Maximum switching voltage	125.0 V rms
Maximum switching current	0.5 A

Figure 70 on page 281 shows an example of the contacts on one unit (PFT1) of the PFTU. Figure 70 shows the contacts in normal operating mode, not in failure mode. Table 77 on page 282 provides the connections for all units on the PFTU.
