Outputs

Analogue output: 4-20mA or 0-20mA current output. Impedance 0~1kW. Accuracy 0.1%. .

Isolated OCT output: for frequency output (0~9,999Hz), alarm driver, or totaliser pulse output, ON/OFF control, etc.
Relay output 1A@125VAC or 2A@30VDC. For ON/OFF control, alarm driver, totaliser output, etc.

Internal Alarm (Buzzer): user programmable.
External Alarm Driver: alarm signal can be transmitted to Relay or OCT output terminals to drive an external alarm. 

RS-232 serial port. 

Input
