MTL4032 is a pulse input safety barrier. The detailed information is as follows:
Single channel, fully floating (Note: "Fully floating" means the input circuit, output circuit, and power supply circuit of the safety barrier are mutually isolated without a common ground. This design can completely eliminate ground loop interference between the hazardous area and the safe area, ensuring stable transmission of pulse signals).
- Hazardous area input: Supports switch or proximity switch signals with a frequency range of 0-50kHz; also compatible with signals from 2-wire or 3-wire voltage-type or pulse-type transmitters.
- Safe area output: Pulse signal (consistent with the frequency and waveform characteristics of the hazardous area input pulse, ensuring no distortion of key pulse parameters such as frequency and edge steepness).
Isolation voltage between the safe area and hazardous area: 250V AC (effectively blocks electrical connections between the two areas, preventing electrical faults in the hazardous area from spreading to the safe area and avoiding signal distortion caused by potential differences).
Voltage range: 20-35V DC
1.35W (low power consumption helps reduce heat generation in the control cabinet and improves the stability of long-term operation in industrial environments).
- Adopts integrated circuit and surface mount technology, featuring high precision (low pulse signal transmission error) and low power consumption.
- Installation method: Backplane mounting (high integration, saving installation space in the control cabinet and facilitating centralized management of multiple safety barrier modules).
- Operating temperature range: -20℃ to 60℃ (adapts to temperature fluctuations in most industrial on-site environments, such as chemical workshops and oilfield well sites).
- 0-50kHz Pulse Frequency: Indicates the range of pulse signals that the safety barrier can stably transmit. A 50kHz maximum frequency means it can handle medium-high speed pulse signals (e.g., pulse signals from a turbine flowmeter measuring liquid flow at a high rate), meeting the needs of most industrial pulse measurement scenarios (excluding ultra-high speed scenarios such as 1MHz servo motor encoders).
- 2-Wire/3-Wire Transmitter:
- A 2-wire pulse transmitter shares power and signal lines (the pulse signal and power supply are transmitted through two wires), with simple wiring and suitable for low-power pulse sensors.
- A 3-wire pulse transmitter has separate power lines (two wires) and a signal line (one wire), which can supply higher power and is suitable for pulse transmitters with additional functions (e.g., self-diagnosis).
- Backplane Mounting: A common installation method for industrial control modules. The safety barrier is fixed on a dedicated backplane, and power and signal connections are realized through the backplane interface (instead of independent wiring for each module). This reduces on-site wiring workload and improves the reliability of the system.
