TCG140-4E is a remote IO module that connects via a GSM/GPRS mobile Network. It has two digital and 4 analogue inputs, plus 1-wire sensor support for temperature and humidity sensor and up to 8 RS485 Modbus channels. Two relay outputs for remotely switching devices (offering both normally open and normally closed wiring options). The controller can be used as a standalone device or as a part of data acquisition (SCADA) systems.

The TCG140 is a versatile GSM-GPRS remote I/O module designed for distributed monitoring and control via mobile networks. It can operate as a standalone device or integrate into larger SCADA (Supervisory Control and Data Acquisition) systems. This module is equipped with a variety of inputs, including two digital “dry contact” inputs, two analogue inputs configurable for a 0-10V range, and an additional two analogue inputs that can be set via a GUI to either 0-10V or 0-20mA. Furthermore, it supports both 1-Wire and RS485 (Modbus RTU) interfaces, each capable of accommodating up to 8 sensors in total, distributed flexibly between the two. All monitored parameters are recorded in the device’s internal flash memory at predefined time intervals or upon alarm conditions, with log files capable of being periodically uploaded to a dedicated server via HTTP Post.
Beyond data acquisition, the TCG140 offers robust control capabilities. It features four relays with normally open and normally closed contacts, which can be activated remotely via SMS, call, or HTTP API commands, or locally triggered by an alarm state of a monitored parameter. The module can proactively initiate connections to remote servers via HTTP Post, sending an XML file containing current parameter values either periodically or when an alarm occurs. This HTTP Post can also receive an HTTP API command in response, enabling remote relay activation or setting changes. For comprehensive alerting, the TCG140 can send SMS messages and/or emails to up to five recipients in addition to HTTP Post alerts.
