Electronic Board; Technical Features - COMEM e170SC Manual De Instrucciones

Electronic board

Perform the connection on the terminal box, following the
indications on the picture.
• Power supply (terminals 1-2): 24 VDC ±10% polarized
• Analogical output (terminals 5-6): 4÷20 mA Minimum /
Maximum resistance: 100 / 470 Ω
• Digital output (terminals 3-4): RS485.
The contact switches when the value of the pressure gets
over the value adjusted. It is possible to adjust this value
through a trimmer on the electronic board or by Modbus.
(See appendix A)
Pre-alarm change-over contact
There are 1 contact for pre-alarm signal:
• 1 x change over contact: pre-alarm signal
(Terminal 42-44-41 --- fig.5)
• NO contact: terminals 44-41
• NC contact: terminals 41-42.
