The TCW260 energy monitoring module includes analog inputs, galvanically separated digital inputs, and an RS-485 interface.
The four digital inputs can all be used with S0 devices. Up to 4 energy meters with S0 pulse outputs can be supported by them. Additionally, generic dry contact output (ON/OFF) sensors can be supported by the digital inputs.
You can use the analog inputs in voltage (0/10V) or current loop (0/20mA) modes. They can be coupled to analog output-compatible voltage and current transducers.
The RS-485 hardware interface is used to implement the MODBUS RTU protocol. Up to 24 registers or devices can be supported by the energy monitoring module.
Up to 24 channels can be configured using all primary parameters (digital and analog inputs, as well as MODBUS RTU registers). The channels can be chosen as follows:
