Part of the Moore Industries FS Functional Safety Series, the exida-certified SIL2/3 capable SLA is a versatile multiloop and multifunctional Logic Solver and Alarm that acts on hazardous process conditions, warns of unwanted process parameters, performs on/off control, and provides emergency shutdown in Safety Instrumented Systems (SIS) and traditional alarm trip applications.
WHY THE SLA IS YOUR SINGLE OR MULTI-LOOP LOGIC SOLVER CHOICE
1. EXIDA CERTIFIED IEC 61508:2010
For systematic integrity up to SIL 3 and for random integrity up to SIL 2. This means that an SLA is approved for single use in SIS up to SIL 2 and in redundant architectures (1002, 2003, etc.) up to SIL 3.
2. DYNAMIC ALARMING CAPABILITY
With up to 16 alarms and eight physical alarm outputs, simple and complex alarming strategies can be implemented with easy to use drop-down menus, radio buttons, and check-boxes. Even complex alarm voting architectures like 1002, 2003, 3005 are simple to employ.
3. SECURE PROGRAMMING & COMMUNICATION
The SLA includes Configuration Security Jumpers that can be set to prevent unauthorized reprogramming and ensure read-only communication through the Ethernet and MODBUS ports.
4. INTUITIVE EQUATION/EXPRESSION EDITOR FOR MATH & LOGIC FUNCTIONS
No PLC programmers required - with the SLA's powerful but easy to use equation/ expression editor you can create monitoring, alarming and control schemes that involve simple to complex equations using timers, running min/max functions, prebuilt analog and discrete logic functions and more.
5. DIGITAL COMMUNICATIONS
The SLA supports MODBUS/TCP and MODBUS RTU industrial protocols. An embedded read-only web server allows all inputs, outputs, internal variables and various other parameters to be read with a simple web browser
