TC-OAH061 Honeywell Analog Output Module – 6-Point Isolated Current Loop
The TC-OAH061 is a Honeywell analog output module built for precise current loop control. It provides 6 galvanically isolated channels with a 4-20 mA output range. Each channel delivers stable, calibrated output for industrial process control. The module suits Series 9000 and compatible Honeywell control systems. Engineers choose it for tight accuracy, fast settling, and robust isolation.

Installation Guide
- Mount the module in a compatible Honeywell backplane slot.
- Use the TC-TBNH 20-position terminal block for field wiring.
- Keep output loads at 500 Ω or less for full 20 mA drive.
- Route signal wires away from high voltage cables.
- Verify backplane current per the power consumption data.
- Confirm channel-to-channel isolation before commissioning.
Commissioning and Maintenance Convenience
The module needs no open circuit detection, simplifying loop design. Electronic current limiting protects each channel from short circuits. Galvanic isolation between channels reduces wiring cross-talk. The 25 ms update rate and sub-2 ms settling speed up loop checkout. Drift figures of 1 µA/°C and 60 ppm/°C support long-term stability with minimal recalibration.
Compatibility Notes
Fits Honeywell control systems that accept the TC-OAH061 analog output module. Uses the TC-TBNH terminal block. Loads up to 1000 Ω may be reached with alternate field terminations. Check the backplane power budget before installation.
Certifications and Compliance
Isolation tested 100% at 2546 VDC for 1 second, channel to channel and user to system. RFI immunity verified to 10 V/m across 27 to 1000 MHz. Contact us for current certification documents.
