Industrial Applications

1. Industrial Process Control for Low-Power DC Loads

This relay can be used to switch 60VDC control signals in industrial process control systems, such as activating small solenoids, indicator lights, or motor starters for auxiliary functions. Its 2 C/O (DPDT) contacts allow for flexible control schemes, and the DIN-rail mount simplifies integration into control cabinets.

Problem Solved

Provides reliable, isolated switching of DC control signals from a 60VDC control circuit to power various low-current industrial devices. The reinforced insulation and 5kVrms dielectric strength between control and load circuits ensure robust operation in environments with potential electrical noise.

2. Building Automation for HVAC or Lighting Systems

The Wago 788-314 can serve as an interface relay in building automation systems, particularly for HVAC damper control or lighting circuit switching where 24VDC signals are used to control 250VAC or 24VDC loads. Its compact 15mm width is ideal for dense cabinet installations.

Problem Solved

Enables safe and compact isolation between low-voltage building automation controllers (e.g., BMS) and higher-voltage or higher-current HVAC actuators or lighting contactors. The DPDT contacts can manage multiple states or feedback signals, and the Push-in CAGE CLAMP connections simplify installation in building management panels.

3. Machine Control Panel Interfacing

In machine control panels, this relay can be used to interface 60VDC control logic with 250VAC or 24VDC auxiliary circuits, for example, enabling non-safety-critical indicators, alarms, or small motor drives based on machine status. Its robust mechanical life ensures longevity in frequently operated systems.

Problem Solved

Provides a durable and electrically isolated interface for routing control signals within complex machinery. It allows a 60VDC controller to safely trigger actions on separate voltage domains without direct electrical connection, minimizing risk of signal corruption and ensuring reliable operation for non-safety-critical functions due to high mechanical life (30 million operations) and specified electrical isolation.
