Littelfuse, Inc. Safety Relays ISS-102ACI-MC

The ISS-102ACI-MC is a multi-function intrinsically safe switch with one Form A and one isolated Form C output relay, designed for pump-up/pump-down or non-latching two-channel switch applications. It operates at 120VAC and allows user selection of debounce time delay (0.5 or 2 seconds) and input sensitivity from 4.7kΩ to 100kΩ via DIP switches. The device features LED indicators for relay states, finger-safe terminals, and mounts on 35mm DIN rail or by surface mounting with #6 or #8 screws. Dimensions are 88.9 mm height, 52.93 mm width, and 59.69 mm depth, with a weight of 0.7 lb. It meets IEC 61000-4-2 (Level 3, 6kV contact/8kV air), IEC 61000-4-3 (Level 3, 10V/m), and IEC 61000-4-4 (Level 3, 4kV) standards, and is certified to UL913 Sixth Edition. Relay contact life is rated at 100,000 minimum electrical cycles at rated load and 10,000,000 mechanical cycles.
