INPUT SPECIFICATIONS

■ AC Current: 0 – 100 mA AC

Input resistance: 10 Ω incorporated

Minimum span: 0.1 mA

Note: The primary current depends upon the number of

windings (winding ratio) of the zero-phase current

transformer.

[Examples]

Winding ratio: 2000 : 1, Transmitter input 0.1 mA

0.1 × 2000 = 200 (mA)

Winding ratio: 133 : 1, Transmitter input 1.5mA

1.5 × 133 = 200 (mA)

OUTPUT SPECIFICATIONS

■ DC Current: 0 – 20 mA DC

Minimum span: 1 mA

Offset: Max. 1.5 times span

Load resistance: Output drive 15 V max.

■ DC Voltage: -10 – +12 V DC

Minimum span: 5 mV

Offset: Max. 1.5 times span

Load resistance: Output drive 10 mA max.; 5 mA for

negative voltage output; at ≥ 0.5 V
