The STB 306 and STB 306/ISO/* terminal blocks let you interface the signals from (circular or linear) incremental encoders to board counter inputs.

The STB 306 terminal block is a passive device. It can be used for input line matching.

The STB 306/ISO/* terminal block feature photocoupled inputs with a high galvanic isolation in order to minimize sensitivity to emissions from noisy environments. It thus meets the IEC 801-4/1000-4-4 standard, level 4 and 5.

The STB 306/ISO/* exists in 4 versions:

A = 5V; B = 12V; C = 24V; D = 48V.

Terminal blocks were designed for applications requiring clear and high-density coupling.
