The new relay versions are all Single Pole Double Throw (SPDT) configuration with screw clamp termination. The five new options include the following versions: 12 VDC, 24 VDC, 24 VUC, 120 VUC and 230 VUC. The three VUC relay versions accept AC as well as DC input signals for greater application flexibility. This feature enables customers to use fewer relay variations, reducing the number of parts in inventory.

The new MICROSERIES Class 1 Division 2 RC version provides an important safety feature that can reduce overall costs and machine downtime. Inductive kickback protection is provided through an integrated RC circuit at the input. This guarantees a safe switching threshold, eliminating leakage currents on the control side. This important safety feature is integrated into the relay so no additional protective circuit or component is needed.

Weidmuller’s new relays also offer users the ability to reduce their installation costs. These MICROSERIES relays have been approved according to UL 508 as well as CSA C 22.2 for use in hazardous locations in the US and Canada. With their compact design, slim 6.1 mm width and DIN-rail mounting, these relays offer quick and easy installation as well as space savings in the panel.  

All MICROSERIES relays feature integrated polarity protection for quick and safe installation. Integrated LED status indicators provide easy and instant troubleshooting to minimize machine downtimes. Weidmuller also offers time saving plug-in jumpers in various colors and pole counts for bridging inputs and outputs from one module to the next, minimizing wiring time and expense.

Installation of electrical devices in hazardous areas presents a unique challenge. Factors that include the presence of flammable gases, vapors or combustible dusts create a potentially explosive atmosphere when combined with air and a source of ignition. Using the correct equipment is crucial in these efforts. Weidmuller recognizes the challenges customer face when working in these difficult environments, and is committed to the design and manufacture of connection solutions for hazardous applications.

Weidmuller is the leading provider of solutions for the transmission of power, data and control signals in industrial environments. The company develops, produces and sells industrial electronics, network infrastructure components and connectivity solutions such as Industrial Ethernet, Relays, Power Supplies, I/O modules, printed circuit board connectors, terminal blocks and complete DIN Rail assemblies.
