Product description
Schneider Electric SR2B121BD is a compact smart/programmable control unit designed for DIN rail mounting. It operates within an ambient air temperature range of -20 to +55°C and offers a memory capacity of 120 lines for ladder programming or 200 lines for FBD programming. This control unit features an IP40 degree of protection for the front panel and IP20 for the terminal block, with 4 contact outputs for digital outputs and a current consumption of 0.1 A without extension. It includes reverse polarity and program memory check protection functions, along with 4 common mode analog inputs. The SR2B121BD requires a 24 V DC supply voltage and utilizes screw-clamp terminals. It has an electrical durability of 500,000 operations with load and a mechanical durability of 10,000,000 operations at no load. The processing time ranges from 6 to 90 ms, and it is equipped with an LCD display. The operating rate is 36,000 cycles/hour with no load and 360 cycles/hour at Ie, featuring a measurement function that checks the program memory on each power-up.
