MCR-SL-PT100 temperature transducers offer a simple, convenient and exceptionally cost-effective method of interfacing Pt100 temperature transducers with instruments and control systems.
If data is to be continually acquired, GPRS is priced according to the volume of data and not the connection time.
The IP connection automatically adopts the modem when started or after dialing via a GSM dial connection.
It does not matter where the system or controller is - the process data is available at any place via a secure VPN connection.
The device has a fully integrated TCP/IP stack so that even simple controllers with serial communications ports can be connected to the modem without special driver implementation.
Two integrated switch entries are particularly helpful for the remote system monitoring.
They allow the automatic transmission of alarm signals via SMS or e-mail.
The extended temperature range from -25 to 60C and the supply voltage range from 10 to 30V enable universal use.
The implemented GSM quad-band technology enables the industry modem, which is designed for rail-mounted assembly, to be used worldwide.
