TC-POA081 Honeywell 8-Channel Analog Output Module

TC-POA081 Honeywell Analog Output Module

• The Honeywell TC-POA081 provides a standard output range of 4mA to 20mA. An extended range from 2mA to 22mA offers additional flexibility for diagnostic purposes.
• The module drives loads from 0 to 500 ohms with a voltage greater than 11V at 22mA. This ensures reliable operation across various field devices and long cable runs.
• Accuracy reaches 0.1% of the signal range with temperature drift of 100 ppm/°C. Transmission error stays within 0.1% at 293K (20°C).
• The TC-POA081 delivers 13-bit resolution with a 4ms response time to 99% of final value. Power consumption measures 0.77 power supply unit load with 5.4W dissipation.

Intrinsic Safety and Electrical Specifications

• This module carries a CENELEC II (1) 2G EEx ia/ib IIB/IIC T4 certification for hazardous area outputs. Permissible field values include Uo = 21V, Io = 93mA, and Po = 520mW.
• The TC-POA081 provides galvanic isolation between outputs and the backplane bus. It also isolates outputs from the power supply per DIN EN 50020 standards.
• Outputs share no isolation relative to each other. The module meets EMC compliance through DIN EN 50081-2, DIN EN 50082-2, and NAMUR NE 21 standards.

Fault Detection and Diagnostics

• The module detects lead breakage when output current drops below 2mA. A flashing red LED on the affected channel indicates a fault condition.
• Fault detection can be disabled per channel group: 0-1, 2-3, 4-5, and 6-7. This allows flexibility for applications where lead breakage detection is not required.
• Latch mode is configurable for channel groups 0-3 and 4-7. This feature holds the output state during fault conditions.
• Alarm signals transmit through the backplane bus for system-level monitoring and diagnostics.

Frequently Asked Questions (FAQ)

Can the TC-POA081 output signals other than 4-20mA?

• Yes, the module supports an extended range from 2mA to 22mA. This extended range helps with diagnostic detection and valve positioning feedback.

What is the maximum load resistance for the TC-POA081?

• The module drives loads from 0 up to 500 ohms. The output voltage exceeds 11V at 22mA to ensure adequate drive capability.

How does the TC-POA081 indicate lead breakage?

• A flashing red LED appears on the affected channel. The module also sends an alarm signal through the backplane bus for system diagnostics.

Can I disable lead breakage detection on the TC-POA081?

• Yes, you can disable fault detection per channel group. Groups are configured as 0-1, 2-3, 4-5, and 6-7 for flexible application needs.

Is the TC-POA081 suitable for hazardous area installations?

• Yes, it carries CENELEC II (1) 2G EEx ia/ib IIB/IIC T4 certification. Always follow permissible field circuit values for safe output operation.
