[Tweet](https://twitter.com/share) ### Get details and specifications for two newly released *groov* I/O modules: GRV-ODCIHC-12 and GRV-ODCIHV-12. Explore more options for your *groov* EPIC system with the release of two *groov* DC output modules. Do your applications require driving high-current or high-voltage DC loads? Take a closer look at how these new I/O modules can help. ##### [GRV-ODCIHC-12 - Drive larger DC loads without interposing relays](https://www.opto22.com/products/product-container/grv-odcihc-12) [![GRV-ODCIHC-12_p_1600](https://blog.opto22.com/hs-fs/hubfs/GRV-ODCIHC-12_p_1600.png?width=250&height=250&name=GRV-ODCIHC-12_p_1600.png)](https://www.opto22.com/products/product-container/grv-odcihc-12)The **GRV-ODCIHC-12** discrete DC output module provides 12 isolated 0–60 VDC output channels, each switching a separate DC load. This module is ideal for applications that require driving high-current loads of up to 6 A per channel, eliminating the need for interposing relays in DC circuits. Typical applications include: - Large solenoid valves - Contactor coils - Brake coils - Industrial lighting - Large DC relays - DC motors - Magnetic locks - Industrial buzzers and horns Industries that can benefit: - Factory automation - Packaging machinery - Material handling - Food & beverage - Water/wastewater - Oil & gas - Automotive manufacturing - Semiconductor equipment Like all *groov* digital modules, the GRV-ODCIHC-12's hinged cover includes an LED array that indicates status, along with a touch-sensitive pad that triggers the *groov* EPIC processor to display module information, including specifications and a wiring diagram. It provides a full set of features, including: - On/off state - On/off totalization - Output pulsing/TPO See the [GRV-ODCIHC-12 data sheet](https://documents.opto22.com/2238_groov_DC_Output_Modules_Data_Sheet.pdf) for complete product specifications.  [![GRV-ODCIHC-12](https://hubspot-no-cache-na2-prod.s3.amazonaws.com/cta/default/439485/c4addc3e-0c7e-41ce-aed4-86844f00938d.png)](https://hubspot-cta-redirect-na2-prod.s3.amazonaws.com/cta/redirect/439485/c4addc3e-0c7e-41ce-aed4-86844f00938d) ##### [GRV-ODCIHV-12 - Connect to DC control systems up to 150 VDC](https://www.opto22.com/products/product-container/grv-odcihv-12) [![GRV-ODCIHV-12_p_1600](https://blog.opto22.com/hs-fs/hubfs/GRV-ODCIHV-12_p_1600.png?width=250&height=250&name=GRV-ODCIHV-12_p_1600.png)](https://www.opto22.com/products/product-container/grv-odcihv-12)The ****GRV-ODCIHV-12**** discrete DC output module offers 12 channels of 0–150 VDC output, each channel switching a separate DC load. This module is perfect for applications that need to drive higher-voltage loads, which are common when reliability over long distances is important, or legacy standards persist. Typical applications include: - Electrical substations - Power generation - Transmission & distribution - Rail & transit - Mining - Marine & offshore - Petrochemical plants - Legacy industrial plants Again, like all *groov* digital modules, its hinged cover includes an LED array that indicates status, along with a touch-sensitive pad that triggers the *groov* EPIC processor to display module information, including specifications and a wiring diagram. This module includes the full feature set: - On/off state - On/off totalization - Output pulsing/TPO See the [GRV-ODCIHV-12 data sheet](https://documents.opto22.com/2238_groov_DC_Output_Modules_Data_Sheet.pdf) for complete product specifications.  [![GRV-ODCIHV-12](https://hubspot-no-cache-na2-prod.s3.amazonaws.com/cta/default/439485/4ab5d311-abc2-4dd0-84ac-b096dabaee84.png)](https://hubspot-cta-redirect-na2-prod.s3.amazonaws.com/cta/redirect/439485/4ab5d311-abc2-4dd0-84ac-b096dabaee84) Both modules are UL/cUL-listed for Class 1, Div. 2 hazardous locations and carry CE and UKCA marks. Each *groov* I/O module is factory-tested twice before shipment, and most are guaranteed for life.  *More questions about these new products?* Start a live [OptoChat](https://www.opto22.com/) with an Opto engineer, use the [Contact Us](https://www.opto22.com/support/contact-us) form on the website, or drop a question in the comments below.
