This model is no longer manufactured and is replaced by NetControl 4R4S1A.

Introduction

This model is designed for general purpose use for remote control and measuring trough Internet. It is derivate of NetControl 4RU1T1A with no voltage measurment circuit. This allows relay channels to control appliances up to 220VAC/7A.

You can open a comparison table of different models from here.

Input-output channels in NetControl 4R1T1A:

  • switch on-off/reboot (normal close relay contact) of up to 4pcs appliances for up to 7A/22VAC (with ability of automatic reboot on PING lost to on IP address)

  • measurŠµment of rack/cabinet temperature or humidity (with external sensor TDS300 or HDS300)

  • integrated "theremoregulator" mode between temperature sensor and of the relay channels

  • alarm input (for mechanical contact/button) for signalization (SNMP trap) of rack/cabinet burglary

  • plastic case dimensions 118x72x35mm

Basic network function (for more see user manual)

  • 10 BASE-T Ethernet (NO CrossOver Autodetect);

  • Supported protocols ARP/DHCP/ICMP/TCP/IP/SNMP/TFTP client/WEB server

  • 802.1q VLAN support

  • SNMPv1 (ONLY snmpget/snmpset) protocol for access to all parameters and functions;

  • SNMP traps generation on input change;

  • Output signal generation on analog input change;

  • WEB access to all parameters and functions;

  • TFTP client for firmware update

Applications

  • Reboot (automatic on PING lost/manual) of hung home network equipment (ADSL modem, routers, APs)
  • "Internet controlled power socket" for 220VAC

  • general purpose 4 channel relay module with Web/SNMP control
  • IP guarding

  • IP thermometer and thermoregulator; IP humidity meter
