Why Choose the Lovato SRPMFA164 Programmable Safety Relay?
The Lovato SRPMFA164 is a versatile programmable multifunction safety relay designed to manage multiple machinery safety functions within a single standalone controller. As part of the Lovato SRP programmable safety relay series, it combines extensive safety inputs and outputs with configurable logic, helping machine builders and automation engineers simplify safety circuits and reduce conventional wiring.
The SRPMFA164 provides 16 digital safety inputs, four independent restart/EDM inputs, four pairs of OSSD safety outputs, four programmable status outputs and four test outputs. It can monitor equipment including emergency stops, safety light curtains, laser scanners, electromechanical interlocks, RFID safety sensors, safety mats and two-hand controls, allowing numerous safety functions to be consolidated within one programmable device.
Operating from a nominal 24 V DC supply, the SRPMFA164 supports machinery safety systems up to Category 4, PLe and SIL 3. Configuration is performed using Lovato SRPSW software, while its compact DIN rail housing makes the controller suitable for installation within industrial control panels and machinery safety cabinets.

Flexible Programmable Safety Control for Industrial Machinery
Programmable safety relays such as the Lovato SRPMFA164 allow multiple safety devices and functions to be monitored through a common configurable controller. Instead of implementing each safety function using separate conventional safety relays, designers can create the required safety logic in software while maintaining dedicated safety-rated inputs and outputs.
The SRPMFA164 can monitor optoelectronic sensors, emergency stops, mechanical safety switches, safety mats, two-hand controls and RFID safety sensors. Its configurable logic supports functions including muting, timers and counters, making the controller suitable for machinery where several interdependent safety functions must operate together while achieving safety performance up to Category 4, PLe and SIL 3.
Typical Applications
- Emergency stop and machinery safety circuits.
- Safety light curtains, photocells and laser scanners.
- Electromechanical and access interlock systems.
- RFID safety sensors and magnetic safety switches.
- Safety mats and sensitive safety edges.
- Two-hand machine control systems.
- Automated production and assembly machinery.
- Packaging, processing and material handling equipment.
