Modules of discrete control and input
|
 The modules are designed for discrete control of different loads and inquiries for status of discrete inputs through the interface RS485 or USB.
FUNCTIONAL CAPABILITIES: - 4 groups of contacts (relay) and 4 discreet inputs
- Maximum switching current is up to 5 A and voltage is up to 240 V
- Galvanically decoupled RS485 and USB 2.0 interfaces
- Can be used as USB to RS485 converter
- Ability to connect a number of devices to one bus
- Control via industry standard ModBus protocol
- Asynchronous registration of input events
- Relays can be flipped for a defined time interval by one command
- Access trough the virtual COM-port when connected to the PC by USB
- Galvanically decoupled inputs can be configured for dry contacts or as voltage inputs
- Reliable and practical enclosure that can be installed on DIN-rail
- Setting and test software for module is supplied
