| TCP/IP-IR Extension Board | ||
| Quick plug-in board | ||
| 8 input expansion | ||
| 4 output expansion | ||
| Easy to add to any IC2000, IC4000, or IC1604 controller | ||
| RS485 connection to other controllers | ||
| LED control on 3rd and 4th door on IC4000 | ||

Sensor have developed a superior solution through the use on plug-in extension boards and satellites. Each IC2000 and IC4000 controller can reach a capacity of 16 inputs/64 outputs, and can also be connected to a TCP/IP network.
The Ext TCP/IP-IR has 8 supervised inputs (4 states) and status LEDs, and 4 outputs and status LEDs. There is an additional terminal for the LEDs of readers 3 &4. It also has a TCP/IP-IR interface through 10baseT, RJ45 connector, and an RS485 bus for connecting up to 32 IC controllers to the network.
