Detailed functions

Selective enabling of modular channels for scanning: improves system flexibility and efficiency.

6 input channels for 3-wire sensors: allows interfacing with 3-wire sensors such as 100ω Pt and 120ω Ni RTDs and potentiometers up to 5k. Each channel features continuous overload protection up to 240Vrms to prevent accidental wiring errors.

Highly accurate measurements: signals from a wide range of sensors can be measured accurately and data integrity is ensured.

Overload protection: The module's overloaded channels do not adversely affect other channels, and transient protection conforms to ANSI/IEEE C37.90.1 standards.

Input-to-Bus Isolation: Featuring input-to-bus isolation, this is a robust 1500Vrms isolation.

Guaranteed Accuracy: The module is guaranteed to be accurate to the f.s., i.e., the last digit is the first digit after the decimal point, for high accuracy.

Field I/O Connection: Field I/O connection is made through pluggable terminal boards for quick and easy wiring.

Separately configured channels for sensors, ranges, alarm limits and averages: ensures that the system is capable of meeting the needs of the most demanding applications.

Alarm Functions: Provides basic high, low, high-high and low-low alarm functions to ensure optimal process flow and fail-safe applications.

Precision, low-amplitude current source: minimises sensor self-heating and eliminates lead resistance errors.

Input Sensor and Input Range Selection: Each channel has an independent input sensor and input range selection function that can be selected for different sensor types and ranges.

Over-range and under-range protection: Over-range and under-range protection functions that allow up to 2% of the specified input value to be exceeded ensure safe system operation.

Sensor linearisation: linearisation can be performed in the module to improve measurement accuracy.
