Littelfuse, Inc. Safety Relays ISS-102AA-DCS

The ISS-102AA-DCS is a two-channel intrinsically safe switch with two Form A output relays, designed for use with resistance probes or switches. Each relay has a corresponding LED to indicate its state. The input sensitivity is fixed at 100 kΩ with a debounce time delay of 0.5 seconds. The enclosure supports surface or 35 mm DIN rail mounting and measures 88.9 mm high, 52.93 mm wide, and 59.69 mm deep. It operates from -20°C to 55°C, accepts 12-20 AWG wire, and requires 3.5 to 4.5 in.-lbs of terminal torque. The device meets UL913 Sixth Edition and IEC 61000-4-2, IEC 61000-4-3, and IEC 61000-4-4 standards for electrostatic discharge, radio frequency immunity, and fast transients. Output contact rating is 5 A at 120 VAC for general purpose use, with a minimum electrical life of 100,000 cycles.
