Overview

Essential details：MTL4544AS Analog input module

Product Description

The MTL4544AS is an analog input module belonging to the MTL 4500 series with the following detailed parameters and features:

Product model: MTL4544AS.
Product Category: Analog input module.
Finish: New/not new.
Delivery time: from stock.
Guarantee: One year.
Express: SF Express/Debon.
Product Type: Single-channel and dual-channel versions (MTLx544A/MTLX544AS) are intrinsically safe isolators located in hazardous areas of processing plants.
Features:
Provides input to the 4/20mA transmitter and allows the HART communication signal to be transmitted bidirectionally on the 4/20mA loop current to query the transmitter from the operator station or hand-held communicator (HHC).
The MTLx541A provides an input area for a separately powered 4/20mA transmitter located in the hazardous zone and repeats the transmitter current to the load in the safe zone.
The MTLx544A supports two identical channels, using two separate transmitters.
The MTLx541AS and MTLx544AS versions act as current-receiving safe zone connections rather than driving current into the load

MTL4544AS

Product parameter

Number of channels: two channels.
Location: Zone 0, IIC, T4-6 Hazardous Zone (if properly certified).
Input impedance: At terminals 1, 2, 4, and 5: > 230Ω.
Maximum input voltage drop: at terminals 1, 2, 4, and 5: < 6.6V, that is, the transmitter load is 330Ω at 20mA.
Security zone output:
Signal range: 4 to 20mA.
Safe zone load resistance (MTL5544A) : conventional transmitters: 0 to 360Ω, smart transmitters: 250Ω ±10%.
Safety zone load (MTL5544AS) : Current receiving: maximum 600Ω, maximum voltage source: 24V DC, safety zone circuit output resistance: > 1MΩ.
Environmental adaptability: Operating in a temperature range from -20°C to +60°C with relative humidity up to 95% (non-condensing).
Installation requirements: Shall be installed in a housing that provides at least IP54 protection class, or shall be installed in a location that provides equivalent protection
