The PLC-BSC-TTL/1 serves as a basic terminal block for TTL signals, measuring 6.2 mm in width. It is equipped with a screw connection and is specifically designed for installation on DIN rail NS 35/7.5. This variant operates without a relay or solid-state relay, supporting an input voltage of 5 V DC.

Constructed in compliance with IEC/EN 60664-1 standards, it features a nominal input voltage of 5 V DC (TTL) and a rated control circuit supply voltage also at 5 V DC. The terminal block's typical response time is 35 µs, with a release time of 320 µs, ensuring reliable operation for TTL signals. The device includes protective circuits for reverse polarity and surge voltage exceeding 6.5 V.

With a maximum switching voltage of 33 V DC and a minimum switching voltage of 3 V DC, it accommodates a limiting continuous current of 3 A while maintaining a voltage drop of less than 200 mV. The operation is indicated by a yellow LED. The ambient temperature range for operation is from -20 °C to 60 °C, while storage and transport conditions can extend from -40 °C to 85 °C.

This terminal block is packaged in units of 10 and weighs 30.94 g including packaging. It features a 2-conductor, floating output circuit and employs a screw connection method for conductors with a cross-section ranging from 0.14 mm² to 2.5 mm². The tightening torque is specified between 0.45 Nm and 0.55 Nm. The product is categorized under the PLC-INTERFACE family and is identified by the item number 2982689.
