Emerson 1C31197G01 Ovation RTD Input Module

Number of input channels: 8. Compatible RTD types: Pt100, Pt1000, Cu10, Ni100 selectable per channel. Wiring configuration: 2-wire, 3-wire, 4-wire. Measurement range: -200°C to +850°C depending on RTD type. Resolution: 0.1°C. Accuracy: ±0.2°C @ 0°C. Isolation voltage: 500V AC channel-to-bus. Backplane current: 380mA @ 5V DC. Power dissipation: 1.9W maximum. Operating temperature range: 0°C to +60°C.

It supports multiple RTD types and wiring configurations for maximum field sensor compatibility. Built-in lead wire resistance compensation improves measurement accuracy. It provides sensor open-circuit and short-circuit detection functions. Per-channel status indicators show operating and fault conditions. Hot-swap capability supports online replacement.

It is widely used for temperature monitoring of process equipment, pipeline temperature measurement, reactor temperature control, bearing temperature detection, and environmental temperature monitoring in power, chemical and manufacturing industries.

Front panel is flame-retardant engineering plastic. Circuit board uses FR-4 glass epoxy substrate. Input circuits use precision reference resistors and low-drift amplifiers. Connectors are gold-plated copper alloy.

It adopts standard Ovation I/O module form factor with front panel status LEDs, channel identification labels, rear backplane connector, and card guide design for rack installation.

It supplies excitation current to RTD sensors through internal constant current sources, measures the voltage drop across the RTD element, calculates temperature values through signal amplification and A/D conversion, and transmits temperature data to the Ovation controller via the system backplane for process temperature control and monitoring.

Install in any available Ovation chassis I/O slot. Use 3-wire or 4-wire wiring for highest measurement accuracy. Match RTD type and range configuration to installed sensors.
