Normally closed output is also available.

Description

The SLR Series has no isolation between the control switch input and the solid-state output. Select the SLR for applications where the control switch is the same voltage source as the load. Provides the noiseless, reliability and long life of a solid-state relay, without the cost of isolation circuitry. The SLR Series offers random switching and is normally used for inductive loads. When fully insulated female terminals are used on the connection wires, the system meets the requirements for touch-proof connections. Operation The solid-state output is located between terminals 1 and 2 and can be ordered as either normally open or normally closed, when voltage is applied and S1 is open. When S1 is closed, the solid-state output between terminals 1 and 2 closes (or opens). If S1 is opened, the solid-state output will open (or close). Reset: Opening S1 resets the output to its original state. Reset is also accomplished by removing input voltage. Features & Benefits FEATURES BENEFITS Compact design measures 2 in. (50.8mm) square Perfect for OEM applications where space is limited T otally solid state and encapsulated No moving parts to arc and wear out over time and encapsulated to protect against shock, vibration, and humidity Up to 20A steady, 200A inrush output rating Provides direct control of heavy inductive, resistive, or incandescent loads Metalized mounting surface Facilitates heat transfer in high current applications Accessories P1015-13 (AWG 10/12), P1015-64 (AWG 14/16), P1015-14 (AWG 18/22) Female Quick Connect These 0.25 in. (6.35 mm) female terminals are constructed with an insulator barrel to provide strain relief. P1015-18 Quick Connect to Screw Adapter Screw adapter terminal designed for use with all modules with 0.25 in. (6.35 mm) male quick connect terminals. Wiring Diagram
