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.
Q10: Is external power required for SCB100?
A10: No, it functions passively within the circuit.
