7.3 - Relay Output (A, B & C)
See 7.1A & 7.1B
Relays A (15A 250V AC or 15A 30V DC) and
B & C (3A 250V AC or 3A 30V DC) should be
wired as shown.

7.4 - Digital Input (G)

See 7.1G
The Nimbus IoT has four Digital Inputs (A–D) which can be con-
figured and scaled using Define WorkBench from the "Digital
Inputs" tab, as per the list below:
Status (active/inactive - can be read by a SCADA system as
›
a general digital input)
› Counter (up to 10KHz, or 100Hz Debounced)
› Frequency (up to 10KHz)
› Flow count (up to 10KHz)
› Flow rate (up to 10KHz)
› RPM (up to 10KHz)
