Product Description

The X20DO4633, a module from B & R Automation part of X20 Series, is designed for high performance digital output applications that require accurate power control. This module has four digital Triac output channels and each channel has to work on 48 VAC to 240 VAC with maximum working voltage of 264VAC. The triac outputs are rated to deliver a nominal output current of 1 A per channel and hence the total current capability of the four output channels is 4 A.

The X20DO4633 has a weight of approximately 120 grams and is quite small yet it is built to withstand different conditions that are found in industries. Some of the features include a zero-crossing detection which is an important function that helps in the regulation of power by detecting the moment that AC voltage is zero. This function makes it easier to get rid of electrical noise and the strain experienced by the other devices. Besides, the X20DO4633 incorporates the zero-crossing detection and phase-angle control. This enables the control of the power delivery which is very important for most applications that need to control electrical loads to a particular level. The module also has an open circuit detection function that assists in the identification of problems in the system.

The X20DO4633 is provided with a minimum holding current of 15mA, hence it can operate when subjected to different loads. Efforts have been made to minimize the leakage currents and the maximum leakage current achieved is 2mA at 50 Hz and 2.4mA at 60 Hz that plays into the efficiency and reliability of the module. The on-state voltage, or the residual voltage is 1.6 V, which also enhances the capability to manage the connected devices in the right and efficient manner.
