MTL Instruments | MTL4532|Pulse Isolator
Description
The MTL4532 is a pulse isolator designed to safely transfer signals from hazardous areas to safe areas. It supports both pulse and 4/20mA current outputs, making it ideal for high pulse rate applications with fast response times. The device can interface with switches, proximity detectors, and current or voltage pulse transmitters.
Features
- Isolation: Safely transfers pulses from hazardous to safe areas.
- High Pulse Rate Handling: Supports up to 50kHz in pulse output mode.
- Configurable Alarm Output: Can be set to act as an alarm using relay output.
- PC Configuration: Configured via personal computer with MTL PCS45 software.
Technical Specifications
Channels and Sensor Types
- Channels: One, fully floating
- Sensor Types: Switch, proximity detector (NAMUR/BS EN 60947–5–6:2001), 2– or 3–wire voltage/pulse transmitter
Input Specifications
- Switch Input: Output ON if switch is closed
- Proximity Detector Input: Excitation 7.0 to 9.0V DC, Output ON if input > 2.1mA, OFF if < 1.2mA
- Current Pulse Input: Supply 16.5V DC at 20mA, Output ON if Iin > 9.0mA, OFF if < 7.0mA
- Voltage Pulse Input: Input impedance > 10kΩ, Switching point voltage (Vsp) 3, 6, or 12V (user selectable)
Safe-Area Outputs
- Pulse Output: Max delay 10µs, Max off-state voltage 35V, Max on-state current 50mA
- Current Output: Signal range 4 to 20mA, Load resistance 0 to 450Ω @20mA, Accuracy better than 20µA at 20°C
- Alarm Output: Relay ON in alarm, 0.5A @ 35V DC max
Power Requirements
- Power Consumption: 65mA at 24V DC, 70mA at 20V DC, 55mA at 35V DC
- Power Dissipation: Max 1.35W at 24V, 1.75W at 35V
