Wattmon Modules

Wattmon modules let you extend the functionality of Wattmon easily. All devices are fully Modbus-RTU compatible and operate over RS-485. They can be used with any third party modbus master if required.

Current Sensing

C1002 Dual Channel 100A Bidirectional Current Sensor

The C1002 device measure two separate current channels using hall effect sensors. You simply need to run the wire carrying current through one of the holes and the current will be measured with an accuracy of 300mA. Multiple C1002 devices can co-exist on the same bus provided they have different IDs.

I3O2 Data Input and Output Module

The I3O2 module has 3 digital inputs that operate at 5V DC and 2 relay outputs that can handle up to 8A at 250V AC. This module is ideal for controlling simple setups such as water tanks, or chargers for battery banks. The outputs can be used to control higher power relays or SSRs if required.

IF1 Frequency and Pulse Counter Module

The IF1 module can be used to measure any pulsed input such as an anemometer or a flow meter. It will give you the frequency in Hz and can measure up to 1/10 of a Hz resolution. The counter values will update automatically with every pulse and can be used to measure volumes.

IP1 PWM Output with Voltage Sense Module

The IP1 module can be used to control a high current through an SSR. Frequencies between 1 Hz and 2 kHz can be generated, with duty cycles of 0 to 100 percent. A 12-bit ADC can be used to measure high voltage inputs and an option can be set to automatically control the duty cycle based on measured voltage. This can be used to control a dump load or small wind turbine easily.
