Emerson 1C31219G01 Ovation Pulse Input Module

Number of input channels: 8. Input type: sinking/sourcing pulse, quadrature encoder. Maximum input frequency: 10kHz per channel. Count range: 32-bit signed. Input voltage: 5-30V DC. Pulse width minimum: 50µs. Isolation voltage: 500V AC channel-to-bus. Backplane current: 320mA @ 5V DC. Power dissipation: 1.6W maximum. Operating temperature range: 0°C to +60°C. Storage temperature range: -40°C to +85°C.

It supports multiple operating modes including totalization, rate measurement and quadrature position encoding. Built-in input filtering suppresses electrical noise and contact bounce. It provides programmable count presets and limit alarms. Per-channel status indicators show operating and fault conditions. Hot-swap capability supports online replacement.

It is used for turbine flow meter totalization, positive displacement flow measurement, motor speed monitoring, encoder position feedback, batch processing volume control, and energy metering in process industries.

Front panel is flame-retardant engineering plastic. Circuit board uses FR-4 glass epoxy substrate with high-speed counter circuits. Input circuits use opto-isolators for galvanic isolation. Connectors are gold-plated copper alloy.

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

It receives pulse signals from field sensors, conditions and shapes the signals through input circuits, counts pulses and calculates frequency/rate values through dedicated high-speed counter circuits, and transmits measurement and totalization data to the Ovation controller via the system backplane for flow and motion control.

Install in any available Ovation chassis I/O slot. Use shielded twisted pair cables for high-frequency pulse signals. Ground cable shields at one end only. Configure operating mode and input type via system software. Ensure reliable system grounding.
