MTL5314 Dual-Relay Trip Amplifier for Hazardous Process Signals
MTL5314 provides precision alarm monitoring for hazardous-area 4-20mA transmitter loops.
The module converts analogue process signals into independent relay alarm outputs for control and protection systems.
Two configurable trip channels allow flexible alarm handling for high-level or low-level process conditions.
The design maintains transparent HART communication while monitoring live transmitter current.
MTL5314 integrates stable switching performance with compact DIN rail installation.
Process Alarm Control Architecture
- Supports 2-wire and 3-wire transmitters
- Dual configurable alarm relay outputs
- Independent trip point adjustment capability
- Maintains uninterrupted HART communication
- Fast analogue-to-relay response characteristics
- Suitable for hazardous Zone 0 environments
- High relay durability for continuous process duty
Global PLC Spare HUB's Insight
MTL5314 performs reliably in applications requiring stable process alarm monitoring without interrupting transmitter communication.
Instrumentation engineers often deploy this amplifier in safety shutdown loops and analogue trip systems.
The dual relay arrangement simplifies alarm separation between warning and shutdown conditions.
The module also supports direct integration with repeater power supplies such as the MTL5541.
Its precise trip-point resolution improves process accuracy during narrow control window applications.
