Feature: 1. SAFE MATERIAL: The signal isolator is made of flame retardant material, with paint spraying, which can protect the circuit from environmental corrosion. 2. STABLE ISOLATION: With photoelectric isolation, anti high frequency interference, realize mutual isolation of input and output, protect power equipment. 3. HIGH EFFICIENCY: Using single chip microcomputer chip, with lower power, higher withstand voltage, PCB transformer, fast transmission response. 4. GOOD PROTECTION: The signal transmitter has good high and low temperature resistance, insulation and shockproof, not easy to moisture, safe to use. 5. SPECIFICATIONS: The DC signal isolator is designed with 2 in 4 out, the power supply is 24V, the input signal is 4‑20mA, efficient and stable in operation. Specification: Item Type: DC Signal Isolator Material: ABS Power Supply Voltage: 24V DC Input Signal: 4-20mA Specification: 2 in 4 out Size: Approx. 114.5 x 99 x 22.5mm / 4.5 x 3.9 x 0.9in . Package List: 1 x DC Signal Isolator Note: Manual measurement, the actual size shall prevail.
