Performance Specifications

Power:

24 Vac with a minimum of 20 Vac and a maximum of 30 Vac at either 50 or 60 Hz. The W7761A power consumption is 6 VA maximum at 50 or 60 Hz. The W7761A is a NEC Class 2 rated device. This listing imposes limits on the amount of power the product can consume or directly control to a total of 100 VA (U.S. only).

The individual Triac outputs incorporate an internal common connection with the input power transformer. The Triacs provide a switched path from the hot side (R) of the transformer through the load to the common of the transformer. The W7761A Device design must use the same power transformer for any loads connected to that device; see Fig. 19.

Each individual Triac is rated 500mA at 30 Vac maximum. Under all operating conditions, the maximum load/source power budget for the W7761A Device is 100 VA.
