FAQ

Q1: What safety integrity level (SIL) is the SLS1508 certified for?
A1: The SLS1508 is certified for SIL 3 applications when installed in a redundant configuration.

Q2: Can each channel on the SLS1508 be configured independently?
A2: Yes, each of the 16 channels can be individually configured as analog input, discrete input, discrete output, or HART two-state output.

Q3: Is channel-to-channel isolation provided?
A3: No, channels are optically isolated from the system, but not from each other.

Q4: What kind of redundancy does SLS1508 support?
A4: It operates in active-active redundant mode, with both solvers processing logic simultaneously.

Q5: What is the power requirement for the module?
A5: The module requires 24 VDC ±20%, 1.0 A plus field power (total max 5.0 A).

Q6: How is failure in one logic solver handled in a redundant pair?
A6: The failed solver is isolated, while the other continues operation without process interruption.

Q7: Is the SLS1508 suitable for hazardous areas?
A7: Yes, it is approved for use in Class 1, Div 2 Groups A-D and ATEX Zone 2 environments.

Q8: Does the system support sequence of events (SOE) recording?
