Teracom TCW260 Energy Monitoring Module (Ethernet)

Description Teracom TCW260 energy monitoring module features galvanically isolated digital inputs, analog inputs, and an RS-485 interface. All four digital inputs are S0 hardware compatible, enabling connection to up to four energy meters with S0 pulse outputs. These inputs can also accommodate general dry contact (ON/OFF) sensors. The analog inputs support both current loop (0/20 mA) and voltage (0/10 V) modes, making them compatible with voltage and current transducers that provide appropriate analog outputs. The RS-485 interface supports MODBUS RTU protocol, allowing communication with up to 24 registers or devices. All primary inputs—digital, analog, and MODBUS RTU registers—can be configured to create up to 24 channels. Channels can be defined as general (e.g., current, voltage, temperature) or cumulative (e.g., energy, volume). Each channel can be monitored numerically or visually through graphs via the standard web browser interface. Each channel also supports up to 24 independent alarms, categorized into four types, with the option to view alarm trends graphically. The module supports M2M communication over Ethernet using SNMP, HTTP API, and MODBUS TCP, enabling seamless integration into larger energy monitoring systems. Features Supports up to 24 channels for voltage, current, or energy monitoring Up to 24 configurable alarms with categorization and flexible setup Graphical visualization of monitored channels and alarms via web browser Four isolated digital inputs compatible with S0 interface (EN62053-31) Digital inputs configurable in ON/OFF or counter mode Six isolated analog inputs supporting 0/20 mA or 0/10 V modes Isolated RS-485 interface supporting up to 24 MODBUS RTU registers Web-based configuration and control with password protection Built-in data logger with capacity for 70,000 records MQTT protocol support Periodic HTTP POST of XML/JSON data for client-server integration HTTP API command support SNMP v2 and v3 support Dynamic DNS support: DynDNS, No-IP, DNS-O-Matic Backup and restore functionality for easy device settings replication Remote firmware updates via the web interface Energy monitoring module TCW260 – User manual  (v1.16) Energy monitoring module TCW260 – Brochure  (v1.3) Energy monitoring module TCW260 – Firmware  (v3.008) Energy monitoring module TCW260 – Firmware change log Energy monitoring module TCW260 – MIB file  (v1.5) TCW discoverer – free utility that finds all TCW controllers in local network, WIN  (v) TCW discoverer – free utility that finds all TCW controllers in local network, iOS  (v1.1) Online demo (admin/admin)
