Applications
- Resistance and temperature measurement: Measures resistance-type transmitters and resistance thermometers, including Pt, Ni, and Cu10 sensors.
- Sensor signal acquisition: Acquires RTD and resistance signals through 2-wire, 3-wire, or 4-wire sensor connections.
Key Features
- RTD input channels: Has 2 analog RTD inputs for resistance thermometers and resistance-type transmitters.
- Sensor connections: Supports 2-wire, 3-wire with internal line-resistance compensation, and 4-wire connections.
- Resolution and accuracy: Provides up to 16 bit resolution with overrange; Pt100, Ni100, Ni120, Pt200, Ni200, Pt500, Ni500, Pt1000, Ni1000, and Cu10 use 15 bit + sign. Accuracy is ±0.1% for resistance-type transmitters.
- Supply and isolation: Uses rated load voltage L+ of 24 V DC from the power module, with reverse polarity protection. The channels are isolated from the backplane bus and load voltage L+, but not from each other.
- Diagnostics and construction: Provides wire-break, group-error, and overflow/underflow diagnostics with a red SF LED. Width is 15 mm; dimensions are 15 mm × 81 mm × 52 mm and weight is approximately 40 g.
