The Analogue Output Module provides an isolated current loop output
that follows the sensor signal level. The output circuit is a passive
current control element that can be operated with loop voltages up to
40V. The recommended connections are shown below:

Fitted with Analogue Output
Module 05701-A-0285
The analogue output can be configured for 0 - 20mA or 4 - 20mA output
modes. Check the configuration sheet supplied with the system to
determine the factory configured operating mode. The operating mode
can be reconfigured easily using a computer attached to the Engineering
Port. Contact Zellweger Analytics or your local agent for more information.
The analogue output can be connected to voltage input device (eg.
chart recorders) by including an external sense resistor in series with
the loop and connecting the device input in parallel with the resistor. ie.
Use a 100 ohm resistor and select an input range of 2V on the chart
recorder.
Relay/Field Interface Card
REMOTE INPUT CONNECTIONS
CAUTION
Connecting voltages in excess of 32V to the remote inputs may
cause permanent damage to the Single Channel Control Card.
There are two remote inputs, RESET and INHIBIT, which are individually
configurable for active high or active low operating modes. Check the
configuration sheet supplied with the system to determine the factory
configured operating modes. The operating mode can be reconfigured
easily using a computer attached to the Engineering Port. Contact
Zellweger Analytics or your local agent for more information.
The switching level of the remote input pins (when enabled) is
approximately +2V with respect to the dc system 0V. The inputs
require less than 5mA drive current and irrespective of configuration
are internally pulled down to system 0V.
Active high remote inputs may be left unconnected or can be connected
to +24V via a normally open contact. The remote input will operate
whenever the contact closes.
Active low remote inputs may be connected to +24V via a normally
closed contact. The remote input will operate whenever the contact
opens. Do not leave active low inputs unconnected.
