Remote Control and Signal Transmission by EES – Flexible and Reliable Solutions for Remote Sites
EES solutions for signal transmission and telecontrols provide secure and stable communication between remote sites, whether you’re working with analog or digital signals. The products support one-way transmission (using the ZS8A module) or two-way transmission (via ZS16 and MFW modules), with communication distances of up to 15 km over two-wire lines, wireless links, or fiber optics.
The modular architecture of the devices enables easy configuration with up to 8 digital inputs/outputs, as well as analog inputs/outputs – an ideal solution for control, monitoring, and signaling in small to medium-sized facilities. The systems support both point-to-point communication and multi-point networks using the flexible and expandable MFW series.
Signal transmission is carried out via encoded digital telegrams, ensuring reliability and immunity to interference – if any communication error occurs, the receiving module automatically detects and rejects corrupted telegrams.
Key Advantages of EES Remote Control and Signal Transmission Systems:
Communication range up to 15 km
Modules with 8 digital inputs and/or outputs
Modules with analog inputs/outputs
Configuration via DIP switches – quick and easy adaptation to specific applications
Suitable for industrial facilities, energy systems, substations, and isolated installations

MODULAR TELECONTROL SYSTEM MFW
Wired or wireless data transmission
The modular telecontrol system MFW is an universal modular telecontrol platform, which excels in its high modularity and flexibility. The concept of the MFW was designed especially for the connection of far distributed outside facilities to a control centre. The MFW system supports a variety of transmission media and can be extended by a soft PLC for automation tasks. For the reliable transmission and evaluation of data telegrams secured protocols are used.

SIMPLE SIGNAL TRANSMISSION
2-wire Multiplexer
The 2-wire multiplexer are ideal for signal transmission in widely ramified water / wastewater, industrial and railway sites and building engineering. The compact units does not demand on quality of the cable that are used for the transmission and have a high immunity to interference in the transmission of analog current or voltage values as well as digital, static signals and counters. For reliable transmission and analysis of the data telegrams secure protocols are used. Depending on requirements data transmission is unidirectional or bidirectional.
UNIDIRECTIONAL 2-WIRE MULTIPLEXER ZS8A
- Unidirectional transmission on control lines up to 15 km distance
- Transmission of 8 binary values, two of it are configurable as counting values
- Expansion possibilities by 8 additional binary values or one analog value
BIDIRECTIONAL 2-WIRE MULTIPLEXER ZS16
- Bidirectional two-wire transmission up to 15 km
- Transmission of commands, messages, measuring and set values
- Modular system configuration up to 16 binary and 4 analog values
