Product Description
The Teracom TCW260 is an Ethernet-connected energy monitoring module designed for industrial energy management, SCADA data acquisition, and building management systems. It combines analog and digital I/O with MODBUS RTU expansion and multi-protocol M2M communication in a single DIN-rail-mountable unit.
What I/O options does the TCW260 provide?
The module features 6 galvanically isolated analog inputs (individually configurable for 0–20 mA current loop or 0–10 V voltage mode, 12-bit resolution, ±1% accuracy) and 4 galvanically isolated digital inputs supporting dry-contact status detection and S0-pulse counting per EN 62053-31. An RS-485 interface with RJ-45 connector adds MODBUS RTU master capability for up to 24 external registers, enabling the TCW260 to aggregate data from third-party sensors, meters, and transducers.
How does the TCW260 integrate with SCADA and IoT platforms?
Beyond MODBUS TCP/IP, the TCW260 supports MQTT 3.1.1, SNMP v2 and v3, and an HTTP API with periodic XML/JSON status posting. This multi-protocol stack allows direct integration with SCADA systems, IoT cloud platforms, and custom monitoring dashboards without intermediate protocol converters. SMTP with SSL/TLS (TLS 1.0–1.2) enables email alerting on alarm conditions, and Dynamic DNS support simplifies remote access over changing public IP addresses.
What data logging capabilities are built in?
An onboard circular logger stores up to 70,000 records across 24 configurable monitoring channels, with data viewable as real-time graphs directly through the integrated web interface. Up to 24 independent alarm channels with 5-state logic provide threshold monitoring per channel. Monitoring channels support both instantaneous values (current, voltage, temperature) and cumulative totals (energy, volume, flow) for comprehensive consumption tracking.
