ZigSense model ZS3G-SMS-P2P is a cable replacer matched pair cellular network controller designed to transfer digital ON/OFF commands between two remote sites where no line of sight is available and the distance between the two sites is extremely far.
The two ZS3G-SMS-2 I/O controllers use different SIM card numbers to communicate over existing 3G/4G cellular networks. Digital inputs support 24 VDC and digital ‘dry’ relay outputs support 125 VAC 3 A. The controller can be powered by 12–24 VDC supply.
The SMS controller can be set up and programmed via English language text messages sent to the controller from a standard mobile phone. There is no need for programming software.
