The Yokogawa UT152-AN/RET is a single-channel intrinsically safe (IS) isolator designed for installation in Yokogawa UTSX Series rail-mounted housings. It functions as a rectifier-type isolator with an additional retransmission output, providing both safety isolation and signal replication. The module accepts a 4-20 mA signal from a 2-wire transmitter in a hazardous area, supplies loop power to it, and outputs two isolated 4-20 mA signals: one for the control system and one for retransmission to secondary devices (e.g., recorders, displays). The "AN" suffix indicates compliance with specific safety standards (e.g., ATEX, IECEx), while "RET" denotes the retransmission output feature.

The Yokogawa UT155-AN is a single-channel intrinsically safe (IS) isolator designed for installation in Yokogawa UTSX Series rail-mounted housings. It functions as a repeater-type isolator, meaning it 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 "AN" suffix indicates compliance with international intrinsic safety standards (e.g., ATEX, IECEx). Unlike rectifier-type isolators, the UT155-AN does not supply power to the field device; it only conditions and isolates the signal.

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 Yokogawa UT150L-RN is a 1/16 DIN size limit controller. It’s designed for safety / process limit control applications — e.g. to trigger alarms or shutdowns when temperature (or other measured variable) exceeds or falls below set limit(s). It features universal input, relay output (for control/limit), optional retransmission, alarms, etc.

The F3LH01-1N is a YHLS (Yokogawa High-speed Link System) master module used for remote I/O in Yokogawa’s FA-M3 programmable logic controller (PLC) system. Its purpose is to serve as a communication hub between a CPU module and multiple slave I/O units, enabling fast, reliable digital signaling over distances with many I/O points. It supports standard FA-M3 base mounting, connects via European-type connectors and is built to industrial environmental standards.

The Yokogawa F3NC34-0N is a high-precision, flexible AC current probe (often called a Rogowski coil) designed for use with Yokogawa's power analyzers and scopes (such as the WT Series, PX8000, or DL Series oscilloscopes).

The Yokogawa F3RZ91-0F is a high-performance, wideband AC/DC current sensor (often referred to as a zero-flux or DC-CT type sensor) designed for precision power measurement with Yokogawa's high-end power analyzers like the WT5000, PX8000, or similar models.

The Yokogawa F3YP24-0P is a multi-channel positioning module (with pulse output) for the FA-M3 series “range-free multi-controller”. It generates pulse trains (position reference pulses) as commanded by a CPU module, allowing open-loop control of multiple axes (typically servo or stepper motors). It supports various control modes, and includes features for fast startup, external triggering, pulse counting, etc.

The F3AD08-6R is a high-resolution 8-channel analog input module. It supports both voltage and current inputs on each channel, with selectable input ranges. It is designed for the FA-M3 (Range-free multi-controller) PLC system by Yokogawa.

The Yokogawa F3DA08-5R is an analog output module designed for Yokogawa’s FA-M3 “range-free” controller series. It provides 8 independent analog voltage output channels. The module supports selectable output signal voltage ranges, high resolution via a 16-bit DAC, fast conversion/update times, and precise control. It does not support current output; only voltage out-puts are allowed for this model. The output range and type are configurable via the module’s mode registers.
