AC Signal Transducer, P21Z – available on request
Description
PRODUCT DESCRIPTION
Measuring transducer P21Z type is destined to a continuous conversion of a.c. current or a.c. voltage without the constant component or frequency into a standard d.c. current or d.c. voltage signal or digital signal.
The transducer output signal is galvanically insulated from the input signal and the supply.
Features P21Z:
input:
100, 250, 400 V a.c.
1 A, 5A a.c.
20?50Hz
output:
0/4?20mA, 0?10V
RS-485? with Modbus protocol
programmable parameters by PD14 programmer and free eCon software
