FBM211

Overview

FBM211: 0 to 20 mA Input Module with 16 group isolated and independent channels.

Input Specifications

• Channels: 16 isolated and independent input channels.

• Input Range (per channel): 0 to 20.4 mA dc (current limited to 33 mA).

• Accuracy: ±0.03% of span.

• Accuracy Temperature Coefficient: ±50 ppm/°C.

• Signal Conversion: A/D signal conversion using a multiplexed Sigma-Delta converter per channel.

• Integration Period: Software configurable.

• Common Mode Rejection: >100 dB at 50 or 60 Hz.

• Normal Mode Rejection: >35 dB at 50 or 60 Hz.

• Input Impedance: 61.9 Ω nominal.

Field Device Cabling

• Distance: Maximum distance depends on compliance voltage, wire gauge, and voltage drop at the field device.

Power Supply Protection

• Loop Power Supply Protection: Each channel is current-limited and voltage-regulated when used with TA RH916BT or P0916BU, limiting short circuit current to 35 mA. If the current limit circuit fails, the current is limited to about 385 mA.
