FAQ

Q1: What is the function of the SCB100-S0?

A1: It detects open-circuit faults in digital input channels where signals are normally off.

Q2: Is SCB100 used for normally on signals?

A2: No, for normally on signals, use the SCB110 model.

Q3: How is SCB100 connected to the system?

A3: It is installed in parallel with the contact output of the field equipment.

Q4: What module is SCB100 compatible with?

A4: It is compatible with the SDV144 digital input module.

Q5: Can SCB100 be used in redundant setups?

A5: Yes, it is suitable for use in dual-redundant configurations of SDV144.

Q6: What does ISA Standard G3 indicate?

A6: It certifies the product for use in environments with dust, corrosive gases, and humidity.

Q7: Can it detect both short and open circuits?

A7: No, SCB100 detects only open circuits. Combine with SCB110 to detect both.

Q8: Does it include wiring?

A8: Yes, each SCB100 unit includes a set of 8 wires.

Q9: What is the weight of the SCB100?

A9: Approximately 0.3 kg.
