900U01-0100

Overview

The 900U01-0100 is a Honeywell Universal Input/Output Module with 16 non-redundant or 14 redundant channels.

Configuration

• Non-redundant UIO configuration: 16 channels (Isolate to rack)

• Redundant UIO configuration: 14 channels (Isolate to rack)

Isolation and Protection

• Galvanic Isolation: 1.5 kV DC (Module to Rack)

• ESCP (Electronic Short Circuit Protection): 620 mA resettable per channel

• Protection: Over-current on one channel does not impact other channels

Electrical Characteristics

• Field Supply Voltage: 24V DC (Typical), 22V DC (Min), 27V DC (Max)

• Load: Max 4.2 Amps per module, 500 mA per channel

• Input Type: Current (2, 3, or 4-wire devices), with HART support

Performance

• Input Channels:

• Non-redundant UIO configuration: 16 max per module (with or without open wire detect)

• Redundant UIO configuration: 14 max per module (with open wire detect)

• A/D Converter Resolution: 16-bit

• Input Range: 0 to 20 mA or 4 to 20 mA (Note: 0 to 20 mA not available for redundant UIO)

• Crosstalk (dc to 60 Hz): 58 dB (channel-to-channel)

• Input Impedance: 250 Ω nominal

• Maximum Input Voltage: 0 ~ 30V (any input referenced to common, no damage)

Accuracy and Conditioning

• Hardware Accuracy:

• 0.1% of full-scale (at 23.5 ± 2°C)

• 0.25% of full-scale (-40 to 70°C)

• Transmitter Field Power Conditioning: Current limited to 24 mA

• Input Filter: First-order low-pass 100 Hz Max

• HART Multi-drop Connection: One device per channel
