Description

Emerson  1C31229G03  digital input module

Technical parameters
The number of channels is 16 (some models have 32 channels).
Input type – Dry Contact: Passive switch (Closed/Open)
Wet contact: 24V DC (typical value, range 10-30V DC)
Logic level high level: ≥15V DC (Logic 1)
Low level: ≤5V DC (Logic 0)

The response time is ≤5ms (dry contact) or ≤10ms (wet contact), including the filtering time
Isolate the voltage at 2500V AC (1 minute) to ensure electrical safety isolation
Power consumption ≤5W (typical value)
Operating temperature: -40℃ to 70℃ (industrial grade), storage temperature: -55 ℃ to 85℃
Protection grade IP20 (Indoor installation, preventing solid foreign objects from entering)

Application scenarios
Equipment status monitoring
It is used to monitor the operating status of pumps, valves, motors and other equipment (such as start-stop status, fault alarm), and to achieve remote monitoring and automated management of the equipment.
Logical control and interlocking
As an input condition for logical control (such as safety door limit signals, emergency stop button status), it participates in the interlock protection of the system to ensure the safety of the production process.
Sequential control
In an automated production line, sensor signals (such as position sensors and photoelectric switches) are collected to provide trigger conditions for sequential control programs and achieve the automatic execution of the process flow.
