Input-output channels in NetControl 4R6I2O

  • 4 normally open relay outputs for load up to 6A/220VAC (12A/24VDC)
  • 6pcs. analog 0 - 10V inputs with 12-bit ADC. Input resistance> 5kOhm. It is permissible to connect the input to the supply voltage (24V) to use the input as an "alarm" (for security this can be done through a series resistor of 5-10k).
  • 2 pcs. analog outputs 0 - 10V (50mV / step, 200 steps) with short-circuit protection. Minimum load resistance 2.2kOhm. at the output (I <12mA).
  • Power supply: 24VDC (18-28VDC), consumption <100mA
  • Housing made of light gray ABS V0 (self-extinguishing); dimensions 105x65x90mm


Basic functions and network protocols supported

  • 10/100 BASE-T Ethernet (Auto MDI/MDIX) with differential overvoltage surge protections
  • Supported protocols ARP/DHCP/ICMP/TCP/IP/SNTP/SNMP/TFTP client/WEB server/MQTT/SPC Cloud
  • 802.1q VLAN support
  • SNMPv1 (ONLY snmpget/snmpset) protocol for access to all parameters and functions
  • SNMP traps and MQTT events generation on input change
  • Flexible user-defined system of sequences of actions (Macros)
  • Start of macros on analog input change (Automation)
  • Start of Macros on PING lost to IP addresses (PING monitor)
  • Real-time software clock (RTC) with the ability to start Macros at user-defined time
  • WEB access to all parameters and functions
  • TFTP client for firmware update

  • Access and control of sensors / drivers with 0-10V interface via Internet
  • Automation systems with remote access via the Internet
  • IP alarm system, such as panic buttons in hotels or security of telecommunication cabinets
  • restart (automatically in case of PING loss / manually) of network equipment (routers, ADSL modems, servers, etc.)
  • general purpose 4 channel relay module with Web/SNMP/MQTT/SPC Cloud control
