Modbus IOs

Digital Input Module 16DI
Used for integration and signaling of up to 16 messages. This includes operating messages, fault notifications
such as frost, filter, or belt, as well as status messages such as damper positions. DIN rail.

Digital Input/Output Module with 3-Point Relay Outputs 4DI2DO-R-3P
Used for controlling two 3-point actuators (OPEN-STOP-CLOSE). The switching commands for the DOs received via Modbus can be manually overridden using switches. Two switches are provided for each of the two 3-point outputs.

Digital Input/Output Module 4DI/4DO-R
Used for controlling four single-stage actuators and signaling messages. The switching commands for the DOs
received via Modbus can be manually overridden using switches. DIN rail.

Digital Output Module 4DO-R
Used for controlling four lighting circuits or similar applications. The received switching commands for the DOs via Modbus can be manually overridden using pushbuttons, allowing for so-called local priority control (LPC).
DIN rail.

Analog Input Module 8AI
Used for integration and signaling of up to eight analog sensor values. Active signals (0..10V) and various passive sensors (e.g., Pt1000, Ni1000) can be connected. If an input is configured for 0..10V, the input signal is indicated by the channel’s respective status LED using light/dark switching (green). DIN rail.

Analog Output Module 8AO
Used for the output of eight 0..10V control signals, e.g., for controlling heating valves, dampers, frequency converters, or similar devices. The switching commands for the AOs received via Modbus can be manually and continuously overridden using switches and potentiometers, enabling so-called local priority control (LPC).
DIN rail.

Digital Output Module with Relay Outputs 8DO-R
Used for controlling eight single-stage actuators or similar devices. The switching commands for the DOs received via Modbus can be manually overridden using switches, enabling so-called local priority control (LPC).
DIN rail.

Digital Output Module 8DO
Used for controlling eight single-stage actuators or similar devices. The switching commands for the DOs received via Modbus can be manually overridden using switches, enabling so-called local priority control (LPC).
DIN rail.
