Contacts, communications and events
- The four potential-free relay outputs consist of three normally open (NO) contacts and one changeover (CO) contact. This model does not have any digital inputs.
- The contacts are rated for a maximum of 48 V for direct switching. Voltages of 110 V or 230 V can only be controlled using a suitable external isolating relay; the module’s own contacts are not designed for this purpose.
- Web administration uses HTTP/HTTPS. OPC UA, MQTT Publish/Subscribe, REST, Modbus TCP, SNMP V1/V2/V3, TCP/UDP and email messages are available. OPC DA is accessed via a separate OPC server.
- Up to 30 configurable actions allow you, for example, to send an email, an SNMP trap, an HTTP request or to change an output. Box-to-Box mode transfers states between suitably configured devices.
Commissioning and accessories
Before connecting, check the connector type, voltage and load current. Connect the network and PoE or an external 12–48 V DC power supply, then configure the IP address, access rights, communication services and event responses. The power supply and other accessories must be ordered separately.

Frequently Asked Questions
What connections does this model have?
The four potential-free relay outputs consist of three normally open (NO) contacts and one changeover (CO) contact. This model does not have any digital inputs.
Can I switch 230 V directly?
No. The relay contacts themselves are designed for the specified load up to 48 V. For higher voltages, a suitable external isolating relay is required.
Is OPC DA built directly into the device?
Direct communication includes OPC UA. For OPC DA, the manufacturer specifies access via a separate OPC server.
