Description
Emerson 1C31234G01
Technical Specifications
- Output channel quantity: 16 discrete output channels
- Output form: dry‑contact relay output
- Rated relay contact capacity: 240 VAC / 2 A
- Operating temperature: 0 °C‑60 °C
Functional Features Every channel uses independent relay component. Channel‑state feedback function. Output‑loop overload protection. Open‑circuit diagnosis capability. One LED status indicator assigned for each channel.
Application Scenarios Remote motor logic control, solenoid‑valve driving and alarm‑lamp output inside thermal‑power‑plant and chemical‑plant Ovation DCS control systems.
Performance Parameters Relay mechanical service life exceeds 10 million operation cycles. Output response time shorter than 15 ms.
Material Composition Flame‑retardant plastic housing. Industrial‑grade relay components. Surge‑absorbing diodes and resistors. Gold‑plated back‑plane connector.
Structural Characteristics Rack‑mount plug‑in card construction. Front‑side wiring terminal block. Front‑panel channel‑status LED indicators. Module locking buckle structure.
Working Principle Controller transmits digital command over back‑plane bus to this output module. Internal logic circuit drives corresponding relay coil actuation. Relay contact closes or opens to switch field‑equipment power‑loop. Module feeds relay‑contact status information back to DCS system for monitoring purposes.
Installation Requirements Mount onto Ovation DCS cabinet back‑plane. Keep field‑power wiring separated from control‑signal wiring. Tighten terminal‑block screws fully to avoid bad contact.
Use Precautions Do not exceed rated relay‑contact load capacity. When switching heavy inductive‑load equipment, install external surge‑absorption accessories. Inspect relay‑contact wear condition on regular maintenance cycles. Replace module when relay‑contact adhesion fault appears.
