Introduction

This is another model in a DIN rail mounting housing, but with a "double-decker" configuration with an increased number of I/O terminals. This is the first model with inputs for temperature sensors type NTC (TNS010) - up to 4 pieces. Another novelty is the two ports for connection to Wiegand readers (for chips, cards, barcodes, etc.). The standard 8 alarm (analog) inputs and 8 pcs. relay outputs are also available. All input-output circuits are led out on screw terminals.

The model supports "Passive PoE In" - it can be powered with (11-15)VDC through the free pairs of the UTP cable: 4/5='+', 7/8='-'

Input-output channels in NetControl 8R4NT2WG8A

• switch on-off/reboot (relay 2xN.O + 6xSPDT) of up to 8 appliances for up to 7A/240VAC (with ability of automatic reboot on PING lost to 8 IP addressеs)
• 4 pcs. input for NTC temperature sensor (TNS010)
• 2 pcs. Wiegand 26/34 input for data transfer from card/chip readers over MQTT (no built-in module for processing interface information)
• 8 alarm inputs for mechanical contact/button or AC voltage detector VDS300 for signalization (SNMP trap,MQTT, SPC Cloud) of events. Other sensors also possible to connect here, as inputs are analog type.
• Housing made of light gray ABS V0 (self-extinguishing); dimensions 105x65x90mm

Applications

• "House/Room Controller" for hotels, guest houses, etc.
• Access control systems with remote control/access over IP
  
• 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 8 channel relay module with Web/SNMP/MQTT/SPC Cloud/ModbusTCP control
• Remote temperature monitoring systems
