Description
The Mercury MR16IN-S3 is a multi-device interface panel that expands a Mercury controller’s monitoring capacity by up to 16 general-purpose input circuits, each individually configurable as normally open or normally closed, and each independently declarable as supervised or non-supervised. Two dedicated programmable relay outputs support fail-safe or fail-secure operation for auxiliary devices. It is the standard choice for adding monitored inputs — door contacts, request-to-exit sensors, tamper switches, and similar auxiliary points — to a Mercury controller (/product-category/hid/mercury/mercury-controllers/) that has run out of native input capacity, allowing standard and range-based supervision with end-of-line resistance. Part of Mercury’s current MR SIO Series 3 module line.
