Video Internet Technologies Company has developed the modules of discrete control and input AVMOD, IO44D, IO44DU. The modules are designed for discrete control with different load and inquiries for status of discrete inputs through the interface RS485 or USB.
FUNCTIONAL CAPABILITIES: 4 groups of contact (relay) and 4 discrete inputs. Maximum commute current and voltage 5А, 240В. Galvanically unbound interfaces RS485 and USB 2.0. The capability to use as interface converter USB-RS485. The capability to plug several devices to a single bus. Standard technical log control ModBus. The means of asynchronous registration of input events. The capability of relay switching for a defined time interval with a single command. Access through a virtual COM-port when plugging to PC with USB. Galvanically unbound inputs with internal tightening resistors or inputs independent from voltage. Reliable and convenient enclosure with opportunity of setting a DIN-rod. Adjustment and testing of a module with help of the software supplied.
