Siemens 6ES7132-6FD00-0BB1 SIMATIC ET 200SP DQ 4x24-230V AC 2A ST Remote I/O Module

The Siemens 6ES7132-6FD00-0BB1 is a SIMATIC ET 200SP digital output module with 4 triac outputs switching 24-230V AC loads at up to 2A per channel and 8A per module, using zero-point detection to limit switch-on transients. It mounts on BaseUnit type B1 and needs an external 10A fast-acting fuse since the BaseUnit provides no short-circuit protection.

Technical Specifications

Selection Notes

Triac switching with zero-point detection turns the load on and off near the AC waveform's zero crossing, which limits inrush current spikes and electrical noise compared to a relay output - relevant for driving contactor coils or small motor starters up to NEMA size 5. This module carries no internal short-circuit protection, unlike the 24V DC sink DQ module in the family, so a 10A fast-acting fuse on BaseUnit type B1 is mandatory before energizing the outputs. At 2A per channel and 8A per module it suits mains-voltage loads directly - pilot lights, small contactors - without an external interposing relay, but a load drawing more than 2A per channel still needs one.

Applications

Switches 24-230V AC loads directly from an ET 200SP station - indicator lamps, small motor-starter coils, solenoid valves rated for line voltage - where zero-crossing switching reduces contact wear compared to a mechanical relay output.
