The 193-EF1A solid-state relay from the E1 Plus Relays series by Allen Bradley is engineered for efficient electrical control applications. It operates based on a current sensing principle and offers a current adjustment range between 20 and 180 A. Users can easily mount this relay using either a DIN rail or screw method, which facilitates straightforward installation.

This relay has a broad control supply range, functioning with input voltages of 24 to 440 V AC or 24 to 48 V DC. The device is compatible with motor circuit voltage ratings up to 1000 V AC and supports control circuit voltages of 440 V AC or 240 V AC. Overload protection is achieved through a thermal trip mechanism, ensuring safety during operation.

The output configuration consists of one normally open contact and one normally closed contact, providing versatility in control applications. It can handle a maximum switching current of 30 A when operating at 240 V, making it suitable for various load conditions. Furthermore, the relay conforms to AC-15 standards with a current rating of 3 A at 240 V.

The 193-EF1A relay features six maximum PTC sensor inputs, enhancing its capability to monitor multiple conditions. The permissible sensor lead lengths reach up to 200 meters shielded for standard applications and 600 meters for specific installations, allowing flexible layout options. For adequate protection, a 10 A gG control fuse is recommended to ensure reliable operation in various industrial settings.
