Functional Features

Independent parameter configuration for every single channel; supports two‑wire and three‑wire thermal‑resistance connection; can serve as PROFIBUS‑DP remote I/O; compliant with UL Class I Division 2 hazardous‑area installation requirement; RoHS compliant; high measurement accuracy up to ±0.1% full scale.

Application Scenarios

Chemical plant process signal acquisition, building automation monitoring system, energy management measurement, industrial furnace temperature monitoring, Freelance DCS system remote I/O cabinet.

Performance Parameters

Stable signal acquisition; adapt to multi‑type field transmitter; high common‑mode interference rejection capability.

Material Composition

Industrial‑grade plastic module housing, analog‑to‑digital conversion circuit board, spring‑type field wiring terminal.

Structural Characteristics

Standard S700 series modular structure; install onto DIN‑rail base unit; front‑side spring‑clamp wiring terminals; rear‑side bus backplane connector.

Working Principle

Collects analog voltage, current signal or thermal‑resistance resistance value from field transmitters and sensors; converts analog signal into digital quantity through internal A/D converter; transmits digital measurement value to ABB Freelance controller via backplane bus.

Installation Requirements

Mount on standard 35 mm DIN‑rail inside control cabinet; implement anti‑static measures before module installation; thermal‑resistance wiring strictly follow two‑wire or three‑wire specification; separate analog signal cable and power cable.

Usage Notes

There is no electrical isolation between internal channels; cannot perform hot‑swap; configure channel signal type in DCS software before putting into service; do not exceed input voltage and current range of each channel.
