The SensorSwitch Mini Secondary Relay Pack switches lighting loads on and off. It can be mounted directly through a 1/2 inch knockout in a junction box, or to be located inside an adjacent box for specific local code requirements. It is commonly used in multi-circuit control applications with one or more units.

Sensor Switch™, MSP20, Secondary Relay Pack, Mini, Series: MSP, 1 hp Power, 120/277 V AC Input, 15 to 24 VDC Output, 20 A, 40 mA Relay, 14 to 160 deg F Operating, 2-1/4 in Width, 1.88 in Depth, 4 in Height, Plastic, Black

• Powers low voltage sensors
• Switches line voltage loads
• Although plenum rated, the elongated mounting nipple allows for the MP-20 to be mounted either directly thru a 1/2 in knockout in a junction box or to be located inside an adjacent box for specific local code requirements
• Mini power packs are the heart of the low voltage sensor system
• The MP-20 transforms 120, 240 or 277 V to class II 15 VDC to power the remote sensors
• Up to 14 sensors may be connected to one MP-20
• Multi-circuit control can be handled by multiple MP-20's and slave packs (MSP-20) may be configured
• MP-20's can be wired continuously hot (line side) or on the switch leg (load side) without nuisance delays upon turn On
