Suitable accessories


The Expert Net Control 2111 offers various remote control options via GSM or TCP/IP network. The device has 4 individually switchable relay outputs and 12 passive signal inputs for polling NO/NC devices. Each signal input has a 3-fold industrial clamp with ground and 12 V connection, so that additional wiring is not required. In addition to 2 power connectors for redundant power supply, the Expert Net Control 2111-2 can also be supplied via Power-over-Ethernet (PoE).

The Expert Net Control 2111 has an easy-to-read LED display that provides information about sensor values, power supply as well as inputs/outputs and GSM status. Thanks to 4 sensor connectors the device can be expanded with optionally available sensors for environment monitoring (e.g. temperature, humidity, air pressure and leakage). Thanks to the sturdy metal housing and mounting brackets, the device has versatile mounting options.
