DESCRIPTION

SD110115 is a Namur amplifier relay designed for inductive or capacitive Namur proximity switches with a single amplifier configuration and relay output. The device features a 10 A SPDT relay output with galvanically separated contacts rated at 250 VAC (rms), and operates from a 115 VAC ± 15% power supply at 50 to 60 Hz. Input specifications include an 8.2 VDC proximity switch voltage with 1 kO internal resistance, supporting activated current of = 1.2 mA and non-activated current of = 2.1 mA, with a minimum pulse time of 20 ms. The amplifier incorporates short circuit and cable failure monitoring, LED indication for output ON status, and operates over a temperature range of -20°C to +50°C. This device is commonly used in industrial automation and control systems where reliable proximity detection and switching are required, offering robust performance in harsh environments with DIN 19234 compliance.
