Three VRs (Zero, Span and Exci) allow the accuracy of the input and output range to be calibrated, and an LED shows whether the module is functioning correctly. The typical bandwidth is 80 Hz.Three-way isolation of 1000 VDC separates input, output and power, and the module operates from a +10 ~ +30 VDC supply with reverse polarity protection. The -G variant is listed with the RoHS-compliant strain gauge signal conditioner description.ApplicationsStrain gauge signal conditioningConverting low-level millivolt sensor signals to standard voltage or current outputsIsolated signal conditioning in industrial control panels

SG-3383 CR is a DC current signal splitter that accepts one 4 to 20 mA input and provides three optically isolated 4 to 20 mA outputs, each linearly related to the input. It offers a cost-effective way to send one process signal to three separate devices.The input is filtered, amplified and split before passing through an opto-coupler to the output stages. Three-way isolation between input, output and power, together with 4 kV EFT protection on the power line and 8 kV ESD protection, helps with ground loop elimination, common mode rejection and noise reduction. Each output has its own zero and span adjustment for calibrating output range accuracy, and an LED indicates module status.Typical uses include splitting a signal for control and validation, separating output devices, or providing redundancy so that one device failure does not disable the entire loop. The module is designed for DIN-rail or wall mounting.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

The SG-3784M converts four 4~20 mA DC current signals into four PWM outputs. Each duty cycle runs linearly from 1 to 100% across the 4~20 mA input range, which makes it a straightforward option where a current loop signal must drive a PWM-controlled load.The PWM frequency is set between 600 and 800 Hz and is adjusted with the four front-panel buttons. A 2.7-inch monochrome graphic LCD shows the duty ratio and frequency of all four PWM channels at once, so commissioning and checking can be done on site without a PC. Input accuracy is ±0.1% of full range.Electrical noise immunity is rated at ±4 kV for ESD (contact, each terminal) and ±4 kV for EFT on the power line. The module runs from a 10 ~ 30 VDC supply with reverse polarity protection and mounts on DIN-rail or wall, with an operating range of -25 ~ +75 °C.ApplicationsHeating systems in buildingsVentilation systemsControlling servo-assisted diaphragm valves
