Description
Pu516a circuit board
The analog output module provides an isolated current loop to output its signal level following the sensor. The output circuit is a passive current control element, and the loop voltage can be as high as 40V.
The recommended connections are as follows:
Analog output + 0V + 24V (10V to 40V)
Relay / field interface card
05701-A-0326
05701-A-0327
05701-A-0328
05701-A-0329
The programmable thinking mode controller isolates the analog output connection, and the power source is from:
PLC 3132 single channel control card
05701-A-03014-20mA
05701-A-0302
The catalytic converter is equipped with analog output module 05701-a-0285. The analog output can be configured as 0-20mA or 4-20mA output mode. Check the configuration table provided with the system to determine the factory configured operating mode.
Operating mode:
You can easily reconfigure ports using a computer connected to a project. For more information, please contact Zellweger analytics or your local agent.
The analog output can be connected to a voltage input device (e.g. A. chart recorder), including and connecting the device input in parallel with a resistor. That is, use a 100 ohm resistor and select an input range of 2V on the chart recorder relay / field interface card remote input connection note that connecting a voltage exceeding 32V to the remote input may cause permanent damage to the single channel control card.
There are two remote inputs, reset and inhibit, which can be configured as active high or active low operation mode. Check the configuration table provided with the system to determine the operation mode configured by the factory. The operating mode can be reconfigured to easily use the computer connected to the engineering port. Contact Zellweger analytics or your local agent for more information.
The switching level of the remote input pin (when enabled) is about + 2V relative to 0V of the DC system. The input requires a drive current less than 5mA, which is internally pulled down to the system 0V regardless of the configuration.
The active high remote input may not be connected or may be connected to + 24V through normally open contacts. The remote input will run whenever the contact is closed.
The active low level remote input can be normally connected to the + 24V closed contact. The remote input will work on whenever contacted. Do not leave the low level input disconnected.
