Description

Emerson  1C31147G01  16-channel digital input module

Basic parameters
Number of channels: 16 independent digital input channels, capable of simultaneously collecting 16 switch signals.
Signal type: Supports two input methods: dry contact (normally open/normally closed) and wet contact (24VDC±20%).
Input logic: It can be configured as low level active (≤3VDC) or high level active (≥15VDC).
Response time: Wet contact input ≤1ms, dry contact input ≤5ms, supporting high-speed state change detection.
Electrical isolation: The isolation between channels and between input and system is ≥1000Vrms, with strong anti-interference ability.

Filtering function: Built-in digital filtering, with configurable filtering time ranging from 0 to 100ms, is used to eliminate contact jitter and electromagnetic interference.
Power consumption: ≤8W. The low-power design reduces heat generation and extends service life.
Operating temperature range: -40°C to + 85°C, suitable for harsh industrial environments.
Installation method: Standard DIN rail installation, supports hot plugging (replace while powered on).

Application scenarios
Power industry: Circuit breaker status monitoring, valve position feedback, safety interlock system (SIS) input.
Chemical engineering and petrochemicals: Emergency stop button (ESD) signal collection, level switch status monitoring, pump/fan operation status feedback.
Metallurgy and manufacturing industry: Signal collection for photoelectric switches on production lines, detection of robot limit switches, and status monitoring of safety light curtains.
Building and energy management: Fire alarm signal access, elevator operation status monitoring, access control system status collection.
