The Yokogawa STB4S-10 is a pressure clamp terminal block designed for digital input signals. It supports single (non-redundant) connections, making it suitable for standard industrial applications that do not require high-availability configurations. It does not include an internal surge absorber, so external surge protection may be necessary in electrically noisy environments. With robust environmental ratings and a rack-mountable design, the STB4S-10 delivers dependable performance for control systems in demanding settings.
