Product description
Product Overview
The MTL 8201-HI-IS is an 8-channel intrinsically safe analog input module for the MTL 8000 series, converting 4-20 mA signals from transmitters in hazardous areas into digital data for the control system. It combines certified IS protection with HART-capable input channels, enabling both process variable measurement and smart-device communication over the same pair of wires.
Core Specs
Channels: 8 analog inputs, 4-20 mA
Input type: 2-wire or 4-wire transmitter loops
Communication: HART digital communication support on input channels
Safety: Intrinsically safe field circuits for hazardous areas
System integration: MTL 8000 / PAC8000 remote I/O platform
Applications: Pressure, flow, level, and temperature transmitters in Zone 1/Zone 2 areas
Highlights
Intrinsic safety certification removes the need for separate barriers on each loop
HART pass-through preserves access to transmitter diagnostics and multidrop configuration
Eight channels in one slot maximize I/O density for analog-heavy process units
High-resolution conversion maintains measurement accuracy across the 4-20 mA span
Channel LEDs and module diagnostics speed up commissioning and fault tracing
FAQ
Q: Can non-HART 4-20 mA transmitters be connected? A: Yes, the module handles standard 4-20 mA loops; HART capability is transparent when not used.
Q: Which field terminal should be used? A: Use the intrinsically safe field terminals specified in the MTL wiring diagram for 8-channel AI IS configurations, such as the 8621/8622-FT-IS series.
Q: Is it compatible with Foundation Fieldbus devices? A: No, this is a 4-20 mA/HART input module; fieldbus networks require dedicated communication interfaces.
Installation Guide
Review the hazardous-area certificate and entity parameters before wiring.
Seat the module on the rack bus and lock it in position.
Connect each transmitter loop through the certified IS field terminal, observing polarity.
Configure channel scaling and HART settings in the host configuration tool.
Calibrate against a reference source and validate communication to each smart transmitter.
Selection Tips
For temperature RTD inputs, choose the 8206-TI-IS module instead.
Confirm the DCS supports HART variable mapping if secondary variables are required.
Group IS loops per certificate limits to preserve certification integrity.
Keep spare AI capacity for future analyzer or transmitter additions.
