The [**SNAP-OMR6T-C**](http://www.opto22.com/site/pr_details.aspx?cid=1&item=SNAP-OMR6T-C) is SPDT (Form C): each of the four mechanical contacts can be used as normally open or normally closed. Your choice. Features: - Four channels per module, each switching AC or DC power - Channel-to-channel isolation and optical isolation - Integrated transient suppression while maintaining minimal leakage current - Each channel can carry 6 amps, and there's no reduction in power when multiple channels are on. Mount the mechanical power relay module on a [SNAP PAC rack](http://www.opto22.com/site/pr_selector.aspx?cid=1&qs=100310111044) alongside other analog, digital, and serial I/O modules. Use a [SNAP PAC brain](http://www.opto22.com/site/pr_selector.aspx?cid=1&qs=100310061044) or [rack-mounted controller](http://www.opto22.com/site/pr_selector.aspx?cid=1&qs=100210241055) for communications and I/O processing. Or you can use this module with legacy SNAP brains—SNAP Ultimate, SNAP Ethernet, SNAP Simple, B3000, B3000-B—and B-series or M-series racks. Read the [SNAP Mechanical Power Relay Output Module data sheet](http://www.opto22.com/site/documents/doc_drilldown.aspx?aid=4149). ## Use SNAP I/O in 3 Ways **Connected to an Opto 22 control system.** With a [SNAP PAC](http://www.opto22.com/lp/pac.aspx) programmable automation controller and [PAC Project](https://info.opto22.com/opto-22-software-suite) industrial control software, SNAP I/O distributes local intelligence to the I/O level for greater system efficiency. **As intelligent remote I/O in another system**. Connect to [Allen-Bradley](http://www.opto22.com/site/io4ab.aspx) industrial PLC systems, use the built-in Modbus/TCP protocol, or use OPC to exchange data with other manufacturers' systems. **For PC-based control.** Develop applications in .NET or C++ using a free [Opto 22 Software Development Kit](http://www.opto22.com/site/pr_selector.aspx?cid=7&qs=100510211057). Or use SNMP to send traps to a network management system, SMTP to email alarms and conditions, or PPP to communicate remotely over a modem. ## Why Opto 22? Industrial and commercial businesses, OEMs, and system designers have used Opto 22 products for more than 40 years to monitor, acquire data from, and control all kinds of machines and devices.  Our field-proven solid-state relays and I/O modules are famous for their reliability. Opto 22 controllers communicate over standard networks using open protocols.  ![Made in the U.S.A.](https://info.opto22.com/hs-fs/hubfs/MadeInUSA.jpg?width=96&name=MadeInUSA.jpg "Made in the U.S.A.")Opto 22 products are designed, manufactured, and supported in the U.S.A. **Product Support is free.** [Learn more about Opto 22](http://www.opto22.com/site/more_about_opto.aspx). -
