PLC Controller with Wifi


EXM-12DC-DA-RT-WIFI-HMI plc controller with WIFI

Product Description:
Incorporates a wide range of CPUs, expansions, various accessories and software, specially designed for GSM/GPRS wireless systems being used for remote measurements, data logging, control, diagnostics and object via short text messages (SMS) or CLIP calls. Configurable messages sending 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 or Call out can be triggered by change of binary input state, reaching alarm thresholds, marker state change, counters and clocks.
