TCG140-4_R1.0 - February, 2021
1. General
TCG140-4 is a 4G LTE Cat.1 universal I/O module. It supports also 3G and 2G wireless
communication and provides data connectivity on LTE-FDD, DC-HSDPA, HSPA+, HSDPA, HSUPA,
WCDMA, EDGE, and GPRS networks.
It has 2 digital inputs, 4 analog inputs, digital interfaces for external sensors, and 4 relays. Two
of the analog inputs can be switched either in a current loop (0-20mA) or voltage modes. The relays
can be activated either remotely (via SMS or HTTP API command) or locally - from the status of the
monitored parameter.
TCG140-4 supports all digital sensors of Teracom.
All monitored parameters and status of relays can be periodically saved in the embedded data
logger. It is possible to arrange records on any alarm condition.
The module supports HTTP API for M2M communication.

3. Powering
TCG140-4 is designed to be supplied by adapter SYS1308-2412-W2E (12V/2.0A) or similar,
intended for use in the conditions of overvoltage category II, and priorly assessed for compliance
with safety requirements. The power supply equipment shall be resistant to short circuit and
overload in a secondary circuit. When in use do not position the equipment so that it is difficult to
disconnect the device from the power supply.
