PHOENIX CONTACT USA Monitor - Relay Output 2866093

The EMD-SL-PTC is a temperature monitoring relay for PTC thermistor sensors in motor windings, with two floating PDT contacts for output signaling. It has a width of 22.5 mm, height of 90 mm, and depth of 113 mm, and mounts on a TS 35 rail. The relay operates from 24 V AC to 230 V AC or 24 V DC via pluggable power modules, with an ambient temperature range of -25 °C to 55 °C and a mechanical service life of approximately 2 × 10⁷ cycles. It meets UL 508 and CE standards, has a rated insulation voltage of 300 V, and supports conductor cross sections from 0.25 mm² to 2.5 mm² for stranded wires. The device detects PTC resistance changes with a response value of at least 3.6 kΩ and a release value of no more than 1.8 kΩ, and includes a test/reset button with error memory.
