Analog input rail conversion board PHED-8AI

Number of channels: 8 (single channel isolation barrier)

Signal type: dual line analog input (temperature, voltage/current), three terminal isolation

Supporting safety barrier: Pinghe series single channel analog input safety barrier, please refer to the safety barrier manual for details

Supporting isolator: Pinghe series single channel analog input isolator, see isolator manual for details

Loop current: LED current indication online test hole

Installation form: rail installation or M4.8 self tapping or M4 screw installation

Supporting card components:

Base: MB74*

Card: AI711

Power supply:

This product is designed for redundant power supply and comes with a power loss alarm output

Attention: The safety barrier isolator does not have the ability to supply power to conventional three wire transmitters. In special circumstances, it can be connected using a four wire system.

Special note:

1. The brightness of the circuit LED can roughly indicate the magnitude of the circuit current;

2. Using a multimeter to short-circuit the current range of this circuit test hole can accurately measure the inner current without affecting the circuit operation;

When the circuit LED fails and opens, a spare LED can be inserted into the test hole for repair;
