TCW260 - energy monitoring module with galvanically isolated ports and Ethernet connectivity.

The TCW260 energy monitoring module supports galvanically isolated digital inputs, analog inputs, and RS-485 interface.
All 4 digital inputs are S0 hardware compatible. They can be used to support up to 4 energy meters with S0 pulse outputs. The digital inputs can also support dry contact (ON/OFF) output sensors.

The analog inputs can be used in current loop (0/20mA) or voltage (0/10V) mode. They can be connected to voltage and current transducers with suitable analog outputs.

The MODBUS RTU protocol is implemented via the RS-485 hardware interface. The energy monitoring module supports up to 24 registers/devices.

All primary parameters (digital and analog inputs and MODBUS RTU registers) can be used to organize up to 24 channels. Channels can be specified as general (current, voltage, temperature, etc.) or cumulative (energy, volume, etc.). All channels can be monitored as digits and graphs directly in a standard browser via the WEB interface.
All channels can be used to organize up to 24 independent alarms. Four categories are available for each alarm. Alarms can also be monitored as graphs.

The module supports M2M protocols over Ethernet: SNMP, HTTP API, and MODBUS TCP. Thanks to them, the device can be used as part of energy monitoring systems.
