4-channel digital output; 30 VAC/VDC; 2.0 A; Solid-state; isolated

This digital output module transmits control signals from the automation device to the connected actuators. The module has four semiconductor switches with very low on-resistance MOSFETs suitable for both AC and DC voltages. The semiconductor outputs are not permanently short-circuit proof so external fusing is required. The control of the semiconductor outputs is galvanically isolated from the internal system voltage. Furthermore, the output channels of the 750-528 I/O Module are also electrically isolated from each other. The field supply voltage is fed to the right-hand modules via the power contacts. The signal states for controlling the four digital outputs are indicated by status LEDs. Notice: If AC voltages are fed via the power contacts or DC voltages >31.2 V are used, a suitable supply module (e.g., 750-612) must be provided!
