Telemetry Module- EXM series CPU is a device which incorporates functions of industrial PLC with integral LCD display, data logger connectivity and Modbus protocol converter which enriching it with robust wireless GSM/GPRS connectivity.  Ethernet and RS232,RS485 ports are optional powerful tools, allows communicating with other devices thus further expanding resources available to be used by user. With compact, robust design, integral GSM modem, attractive technical features and easy to use configuration tools.

It is a ideal device dedicated for remote monitoring, diagnostics and control of objects via short text messages (SMS), CLIP calls or e-mail. Configurable messages send from device with static (text) or 
dynamic (text and measured values) content are a convenient way of passing important information to the monitoring center, or directly to the defined phone numbers. SMS messages sending can be
 triggered by change of binary input state, reaching alarm thresholds, marker state change, counters and clocks. Multiple optional analog signals (0..10V DC) (0…20mA) ,(PT100) inputs built-in the
 module  or  expanded, make it possible to have direct connection of sensors, which lowers the cost of building system.
Hence, it can directly work with humidity sensors, water level sensor, pressure transducers, flow sensors, smoke,gas, motion, shock and noise detectors, etc.

Hence the EXM series module is an optimal solution for demanding wireless telemetry, control, diagnostic, surveillance and alarm systems.
