The Model 10A16-4C, Four Channel RTD Conditioner is designed for high-accuracy temperature measurement using platinum Resistance Temperature Detectors (RTD's). Precision constant-current excitation is provided for four independent sensor channels, which may be intermixed as required. RTD inputs are normally set for four-wire cabling, with maximum excitation of one milli-ampere and input impedance of 10 MOhms, to eliminate common self-heating and cable-loading errors. However, for an RTD channel with shared current return and sense signals, three-wire mode is available, if desired, via an internal jumper setting.
RTD Types can be Platinum; DIN (European) standard with “ice-point” resistance of 50, 100, or 200 ohms, or American standard with “ice-point” of 100 ohms. The measurement range and resolution is controlled via the System type code that is established by the user with internal digital linearization; maximum error: ±0.1°C (±0.2° F).
