Physical Characteristics and Installation
This digital output module weighs approximately 0.62 kg for standard rack mounting. Its dimensions measure 250 mm x 25 mm x 210 mm for S5 single-width slots. First, slide the 6ES5458-7LB11 into a free I/O rack position. Then, connect your loads to the screw terminals. Finally, secure the module using the top and bottom locking screws. LED indicators on the front show the status of every output channel.
Relay Specifications and Switching Ratings
The 6ES5458-7LB11 provides 8 form A (normally open) relays for load control. Each relay switches 250V AC or 30V DC maximum. The continuous current rating reaches 2 A per channel for resistive loads. Inrush current handling goes up to 5 A for 20 milliseconds. Mechanical life exceeds 10 million operations. Electrical life reaches 100,000 operations at rated load.
Power Requirements and Isolation
This module draws 120 mA from the 5V DC backplane for logic circuits. The relay coils require an external 24V DC supply drawing 200 mA when fully active. Coil-to-contact isolation exceeds 1500V AC for safety. Channel-to-channel isolation prevents cross-talk between outputs. The 6ES5458-7LB11 suits mixed AC/DC load switching applications.
