NL-8DI-4R Discrete I/O module

Module discrete input-output NL-8DI-4RPurpose:designed for discrete input-outputConnection:8 channels of discrete input with group isolation4 relays with normally open contacts 2A =30V or 0,25A ~220V per relay contact. To each terminal of the module is connected to 2 relay contacts (contacts are connected in parallel), ie the actual current of the terminal of the module is approximately equal to 4A at 30V or 0,5A at 220VDisplay:LED indication of the state of inputs and outputsProtection types:11 types of protection: from overvoltage and current overload on input, output, interface, from overheating, static electricity, etc.Galvanic isolation: galvanic isolation voltage of 2500 VCurrent consumption: reduced current consumption on the inputs (less than 2 mA)Logic zero level: no more than 2 VLogic one level: 3 ... 30 VTemperature: operating temperature range from -40 to +70 SIInterface connection: RS-485 interfaceProtocols: default protocol - DCON (ADAM-compatible...
