Product Description:

The KL2712 Bus Terminal is a 2 channel triac output module for AC voltage switching. It operates within a voltage range of 12 V AC to 230 V AC. Each channel supports a maximum steady load of 0.5 A. The model features independent outputs with LED signal indication and is suitable for mechanical reverse motors.

The KL2712 bus terminal uses triac technology for switching that eliminates mechanical wear. It offers a nominal voltage range between 12 V AC and 230 V AC. The maximum output current per channel is 0.5 A. it supports ohmic and inductive loads. The rotating field frequency operates between 47 Hz and 63 Hz. The terminal integrates surge voltage protection greater than 275 V AC. It withstands a peak current of 40 A for 16 ms and 1.5 A for 30 seconds. Switch on time is 0.1 milliseconds while switch off time corresponds to half the AC period. The maximum residual voltage is 1.5 V. The model is designed specifically for mechanical reverse motors like blinds but is not recommended for LED control. It uses compact terminal housing made from durable polycarbonate. The protection rating is IP20 with variable installation positions. Stripping length for wiring is between 8 mm and 9 mm and current load for power contacts can reach up to 10 A.

Light emitting diodes in the Beckhoff KL2712 bus terminal display the signal state for operational status monitoring. The wiring system is pluggable and compatible with all KSxxxx Bus Terminals. It features 2 make contacts for reliable switching applications. The product ensures consistent operation even under fluctuating load types. It is ideal for systems requiring quick response times due to its fast switching capabilities. The unit supports flexible installation needs through its versatile design.
