505-4532 | Siemens 1/2 A DC Output Module

The 505 Discrete Input and Discrete Output modules contain 8-, 16- or 32- input or output circuits and can accept AC or DC voltage, depending on the modelThe 505 Relay Output Modules (see Figure 1-1) may contain 8-, 16- or 32-output points. (See Appendix A for number of points contained in eachmodel.) These modules are particularly valuable for applications where:• A “no leakage” output is mandatory in the off-state condition.• Load currents must be isolated.• A mixture of voltages must be connected to the same module (forexample, 24 VDC and 24 VAC).The 16- and 32- point relay modules are equipped with four isolatedcommons, and can switch either AC or DC power at each common. The8-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 lesssusceptible than other DC-type modules to inductive load transients whenthe outputs are turned on or off
