4-channel bi-directional wireless remote control. INTRODUCTION 4-channel bi-directional. 2 SRR4 are required. Industrial RF communication 802.15.4 2.4GHz, world-wide license free band. Designed for industrial use. Panel mount “96x48mm”. Plug & Play. Remote control is based in two associated SRR4 devices with communication by RF. Both devices work simultaneously as a transmitters and receivers. The inputs state of one device appears in the outputs of the other device. Input There are 4 inputs available. Each one actue closing circuit between input and a common terminals. The state of each input will be replicated in each output SRR4 associated. Output There are 4 outputs available. Dry contact relays. Remain activated (relay contacts closed) while remain actuated their corresponding inputs in the SRR4 associated. Range Indoor/Urban: 60 meters maximum. Outdoor. Line-of-sight : 750 meters maximum. Led indicators There are 11 leds available to indicate next states : • Input state: 4-green leds. Light while remain actuated. • Output state: 4-red leds. Light while remain activated. Configuration Both units are factory-configured. Twin units share the same DL and MY parameters, but exchanged. DL and MY parameters are written in the unit label.
