API API4380GD

Input signal range: voltage from 0‑50 mV up to ±10 V; current from 0‑1 mA up to 0‑20 mA. Output signal range: 0‑1 V to ±10 V voltage, 0‑2 mA to 20 mA / 4‑20 mA current. Full three‑way isolation reaches 2000 V between input, output and power supply. Response time is less than 10 ms. Input impedance: minimum 1 MΩ for voltage input; typical 50 Ω for current input. Power‑supply option: 115 V AC or 9‑30 V DC. Mounting mode: 8‑pin octal socket, compatible with DIN‑rail or panel mounting. Equipped with LoopTracker input‑output status LED indicators and functional test push‑button. Accuracy is ±0.25 % full scale.

Field‑configurable multiple input‑output ranges by external mechanical switches without software tool. Full three‑way isolation eliminates ground loop interference and suppresses common‑mode noise. LoopTracker LED indicators dynamically display input and output signal level intensity. Built‑in functional test push‑button for quick output verification. Hot‑swappable plug‑in structure for convenient replacement. Built‑in loop power supply for input side and output‑side field devices. Multiple signal conversion combinations can be realized on single hardware unitHGSI.

Industrial ground‑loop elimination for analog signal, signal conversion between field sensor and PLC / DCS / data acquisition equipment, signal level matching for process monitoring instruments, noise suppression of analog measurement loop, industrial panel‑meter signal conditioning, factory‑automation signal isolation in mixed multi‑ground‑potential system.

High linearity for input‑output signal conversion. Optical isolation structure provides high‑strength electrical separation. Quick response time satisfies dynamic process signal change. LED indicator brightness changes synchronously with signal amplitude. Test button can trigger fixed output state for on‑site troubleshooting.

ABS plastic instrument housing, FR‑4 printed circuit board, optical isolation coupling components, multi‑position rotary and slide setting switches, LED indicator lamps, test push‑button, 8‑pin octal metal‑plated pin base, surge‑protection passive components.

Plug‑in octal base structure. Main body can be pulled out from octal socket without rewiring. Configuration switches and status indicators are exposed on top surface of housing for convenient on‑site adjustment. Octal socket supports DIN‑rail mounting or direct panel mounting. Compact overall dimension occupies small installation space.

Field DC voltage or current signal enters input circuit of API4380GD. Input signal is conditioned and transmitted to output side through optical isolation component to realize electrical separation between input and output. External rotary and slide switches define input signal range and target output range. Isolated output circuit generates linear‑corresponding DC voltage or current signal according to set range. Built‑in power‑supply isolation circuit separates power‑supply domain from both input and output domains to achieve three‑way isolation. LoopTracker LEDs obtain signal sample from input and output circuit to indicate real‑time signal level. Functional test button triggers preset output level for hardware function verification.

Install 8‑pin octal socket on DIN‑rail or equipment panel. Complete power‑supply wiring and input‑output signal wiring on octal socket terminals. Insert API4380GD main unit firmly into octal socket. Adjust rotary and slide switches according to required input‑output range referring to range table printed on housing. Confirm power‑supply type matches hardware power‑supply variant. Keep instrument away from high‑temperature heat source and strong vibration source.

Do not exceed maximum permitted input voltage and current. Confirm switch‑setting position before power‑on. Check octal socket terminal wiring to avoid short‑circuit. Power‑supply variant cannot be modified on‑site; select correct hardware model according to on‑site power‑supply condition. Use test button for function check during regular maintenance. Keep housing surface switch‑area free of dust accumulation. Operate within industrial ambient temperature range.
