ZigSense model ZS3G-SMS-P2P cellular network controllers
The 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.
Starting or stopping a remote pump and receiving feedback or alarms about the pump’s condition can be done by sending an SMS command straight from a mobile phone to the remote pump. Alternatively, a local PLC can toggle a start/stop output which is wired to the local SMS controller. The local SMS controller then sends a text message to the remote SMS controller (wired to the remote pump), which in turn opens or closes a relay contact associated with the pump.
At the same time, alarm conditions existing at the remote pump site will send a text message back to the local PLC, which will be recognised by the PLC logic and at the same time advise the operators of the alarm condition by issuing SMS messages to their mobile phones.
The two ZS3G-SMS-2 I/O controllers use two different SIM card numbers to communicate over existing 3G/4G cellular networks. Each controller supports two digital inputs (24 VDC max) and two ‘dry’ digital outputs (125 VAC, 3A).
The controller can be powered by a 12–24 VDC supply. Set-up and programming of the ZS3G-SMS controller is achieved by issuing English-language text commands sent to the controller from a standard mobile phone. There is no need for programming software.
