IDEC Relays SU4S-21L Relay Base 326058-756 Real-Time Diagnostics: SensorCheck microprocessor monitorsThe IDEC SU4S 21L Relay Base is a high performance 4 pole socket specifically engineered for DIN rail mount systems. This unit is the direct replacement for the obsolete SU4S 11L and is fully compatible with RU4S and RU42S series relays. Unlike standard screw terminal bases, the SU4S 21L utilizes push in terminals, which can reduce field wiring time by up to 55%. This tool less termination ensures vibration radiation resistance and eliminates the need
