رله بریرمدل MTL5024

The MTL5024 allows an on/off device in a hazardous area to be controlled by a volt-free contact or logic signal in the safe area. The MTL5024 is suitable for driving loads such as solenoids, alarms, LEDs and other low-powered devices certified as intrinsically safe or classified as non-energy-storing simple apparatus. A phase reversal switch enables the user to select which phase of input signal will drive the output on

Number of channels One Location of load Zone 0, IIC, T4–6 hazardous location if suitably certified Div. 1, Group A hazardous location

Safe-area input Suitable for switch contacts, an open-collector transistor or logic drive. Normal (reverse) phase: output on (off) if switch closed, transistor on or 4.5V applied to input Hazardous-area output Minimum output voltage: 12.85V at 45mA Maximum output voltage: 25V Current limit : 45mA Phase reversal Selected by a switch on the base of the module

LED indicators Green: power indication Yellow: status

Supply voltage 20 to 35V dc

Maximum current consumption 100mA at 24V 120mA at 20V dc 75mA at 35V dc

Maximum power dissipation within unit 1.4W with typical solenoid valve, output on 2.0W worst case

Safety description 25V, 170Ω, 147mA, Um = 250V rms or dc
