It provides a robust dry-contact interface rated for up to 300V peak, 130 mA DC, and 400 mW, with two modes—simulate dry contacts and read dry contacts—and a frequency-indication LED that pulses in step with the signal; the device does not require calibration, though an annual performance check is recommended when used with the 942 calibrator. Manufactured by ALTEK INDUSTRIES CORP., Rochester, NY, the C-41 carries part number PN 1887857 Rev A (April 2002).\u003c\/p\u003e\u003c\/div\u003e","brand":"altek","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659870175534,"sku":null,"price":413.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_fff1b5e6-d382-4eb9-a246-c6ca858613e8.jpg?v=1769530304","url":"https:\/\/plgautomation.com\/products\/altek-c-41-dry-contact-module","provider":"PLG Automation ","version":"1.0","type":"link"}
