Description

The 16- and 32- point relay modules are equipped with four isolated commons, and can switch either AC or DC power at each common. The 8-point module is equipped with 8 isolated commons (one for each point) and can switch either AC or DC power at each point. These modules are less susceptible than other DC-type modules to inductive load transients when the outputs are turned on or off.

The 32- and 16- point modules (PPX:505–4932 and PPX:505–4916) provide normally open (Form-A) contacts, while the 8-point module (PPX:505–4908) provides both normally open and normally closed contacts (Form-C). The PPX:505–5417 and PPX:505–5518 provide both normally open and normally closed contacts (Form-C).

The PPX:505–5518 module provides snubbers on the normally open contacts. This snubber should be used with inductive loads to extend the contact life. The snubber is composed of a series 330 Ω resistor and a 0.1 µf capacitor. If the load requires a “dry contact” relay then the snubber can be disconnected. To connect the snubber, move the shorting plug associated with the output point, to on. For example, for a normally open output 5 the snubber is controlled by E5. See Figure 3-14 for a typical connection.
