DEIF

1.Main Functions

1. AC current measurement and signal conversion Measure sinusoidal alternating current (45‑65 Hz). Input accepts secondary AC current from current transformers (typical 0‑1 A AC or 0‑5 A AC). The internal transformer implements rectification, filtering and amplification, and converts AC input into linear proportional standardized DC output signal (0‑20 mA DC or 4‑20 mA DC).
2. Galvanic electrical isolation Built‑in isolation transformer provides 2200 V AC / 1 min galvanic separation between input circuit, output circuit and auxiliary power supply circuit. It blocks high‑voltage common‑mode interference, protects downstream PLC, meter and control equipment from surge damage.More products: www.plcva.com

DEIF TAC‑321DG Single‑Function AC Current Transducer

1. Overload withstand capability Supports 2× nominal continuous overload; 10× nominal current for 10 seconds; 40× nominal current for 1 second, to adapt to transient current surge in industrial power systems without internal hardware damage.
2. Standard DIN‑rail installation and wide‑range auxiliary power supply Compact DIN‑rail snap‑on mounting design for cabinet installation. Accepts common industrial auxiliary power. Screw‑type terminal blocks facilitate quick field wiring and commissioning. Max output load resistance ≤ 600 Ω for current output mode.More products: plcva.com
3. Stable analog output with low ripple Smoothing circuit reduces output ripple. Typical response time less than 150 ms. Deliver steady DC analog signal for acquisition devices. No software configuration required; performance depends on factory preset range settings.
4. Robust environmental adaptability Operating temperature range:‑25 °C ~ +70 °C; storage temperature‑40 °C ~ +70 °C. Designed for harsh electrical cabinet environments with vibration and electromagnetic interference.

Core operational purposes:

• Isolate high‑potential AC current‑transformer secondary signals and convert them into standard 4‑20 mA / 0‑20 mA DC analog signals
• Provide readable current measurement signals for PLC, SCADA, digital indicators, alarm units and recording instruments
• Realize remote current monitoring for generators, feeders and large‑capacity motors
• Protect automation control equipment via galvanic isolation against power‑system surge noise
• Support power‑system status monitoring, load observation and overload early warning for marine and land‑based power facilities.
