The Yokogawa UT155-VR/RS is a specialized single-channel intrinsically safe (IS) isolator designed for installation in Yokogawa UTSX Series rail-mounted housings. It combines the functionality of a repeater-type isolator with a remote reset (RS) capability, making it suitable for critical safety applications where remote alarm management is required. The module accepts an active 4-20 mA signal from an externally powered device (e.g., a 4-wire transmitter) in a hazardous area and provides an isolated 4-20 mA output to the safe area. The "VR" suffix indicates operation with a 24 V DC power supply, while "RS" denotes the remote reset functionality for alarm conditions.

The ABB AF750‑30‑11 is a 3‑pole, block‑type industrial contactor from ABB’s AF series, designed for three‑phase motors and general power‑circuit switching. It supports a wide-range control (coil) voltage, allowing stable operation under varied control‑voltage conditions. The contactor is built to handle heavy loads, making it suitable for motor starting, isolation, bypass, distribution, and general industrial power applications up to 1000 V AC. It includes one normally‑open (NO) plus one normally‑closed (NC) auxiliary contact (the “‑11” configuration), offering flexibility for control or signaling circuits. Its modular design and robust build allow use in motor control centers, switchgear, and other heavy‑duty installations.
