INTENSITY CONTROL FOR MAXIMUM AND MINIMUM CURRENT

Description
Especifications

ZCIx3xx maximum and minimum current control relay with built-in toroid: 5, 10 and 20 A ranges, block or enable control input.

Product type:	Maximum and minimum current control relay
Installation:	DIN rail, 1 module
Measurement:	Built-in toroid: one phase is passed through the hole

How it works

1One phase of the supply of the system to be monitored is passed through the hole on the side of the unit.
2With no current, the output is off and the minimum LED is on.
3When the current reaches the set minimum, the minimum LED goes off and the output switches on. The minimum is set as a percentage of the maximum.
4If the current exceeds the set maximum, the output switches off and the maximum LED lights up.

Frequently asked questions

Does it need a current transformer?

No. The toroid is built in: just pass one phase through the hole on the side.

How is the reference read?

ZCI + control input (V none, B block, P enable) + function (3: maximum and minimum) + range (05, 10 or 20 A). For example, ZCIB310: with block, 0 to 10 A.

Which supply does it use?

230 VAC or 24 VAC/VDC. It must be stated in the order.
