Functional Features: Channel-level open-load/output-fault diagnostics, HART loop compatible, hot-swappable tool-less latch, software range per channel.
Application Scenarios: Boiler feedwater valve control, damper actuators, VFD speed command, analyzer sampling sequence in power and process DCS.
Structure & Material: Ovation 1U I/O card, isolated DC/DC per bank, plastic shell, metal backplane.
Working Principle: Controller writes output value; per-channel DAC drives isolated current/voltage stage; fault comparator watches load current and reports back.
Installation Requirements: Ovation I/O chassis 1U slot, STP wiring, shield grounded at cabinet bar only, total loop R ≤ 250 Ω for mA.
Usage Notes: Hot-swap allowed with chassis powered. Do not exceed 250 Ω or output clips. Configure range in Ovation engineering station before field cutover.
