Relay I/O Module

I/O Module 4 Relays 8 DI

The WP8024 I/O Module comes with a 24V DC DIN rail power supply and connects to the Climkit Gateway via RS485-Modbus (similar to electric meters).

It features 4 relays that can be used to control devices such as water heaters, heat pumps, pool pumps, etc.

Potential-free contacts (e.g., SG-ready from the heat pump) can be directly connected to a relay on the module.

In the case of a water heater, the relays of the module control command relays (contactors) that in turn switch on the water heater.

A three-phase water heating resistor can be connected with an independent relay for each phase to allow staged activation and maximize self-consumption even during low photovoltaic production.

If 4 relays are insufficient, multiple modules can be connected to the Gateway.

It also has 8 digital inputs (DI) which are for example used to detect the signal from a DSO meter for load shedding of charging stations.

Comes with a 24V DC DIN rail power supply.

3-Position Switch

It is recommended to install a 3-position switch between the relay module and the device to be controlled to enable manual activation.

Positions:

  • Up (I): Automatic controlled by the relay module and optimization system
  • Middle (0): Forced Off
  • Down (II): Forced On

Typical Model: Hager SFB116
