INTRODUCTION
The DL series analog input process meter is a multi-purpose, easy-to-use digital
process meter ideal for level, flow rate, temperature, or pressure transmitter
applications. It accepts current and voltage signals (e.g. 4-20 mA, 0-10 V). Three
of the front panel buttons can be custom-programmed for a specific operation.
The analog input can be scaled to display the process in two different scales; for
example, the main display could indicate level in feet and the second display
could indicate the volume in gallons.
The basic model includes an isolated 24 VDC transmitter power supply that can
be used to power the input transmitter or other devices. An additional isolated
24 VDC power supply is included with the 4-20 mA output option. A digital input
is standard.
A fully loaded meter has the following: four SPDT relays, 4-20 mA output, and two
24 VDC power supplies. Its capabilities may be enhanced by adding the following
external expansion modules: four SPST relays (creating an eight-relay process
meter), two digital I/O modules with four inputs and four outputs each, and USB,
RS-232 or RS-485 communication adapters.
The eight relays can be used for alarm indication or process control applications
such as pump alternation control. The 4-20 mA isolated output, Modbus RTU serial
communications, and digital I/O options make it an excellent addition to any
system.

Panel Mounting Instructions
• Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm x
45 mm). Refer to Figure 1 below, for more details.
• Clearance: allow at least 6.0" (152 mm) behind the panel for wiring.
• Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).
Recommended minimum panel thickness to maintain Type 4X
rating: 0.06" (1.5 mm) steel panel, 0.16" (4.1 mm) plastic panel.
• Remove the two mounting brackets provided with the meter (back-off the two
screws so that there is ¼" (6.4 mm) or less through the bracket. Slide the
bracket toward the front of the case and remove).
• Insert meter into the panel cutout.
• Install mounting brackets and tighten the screws against the panel. To
achieve a proper seal, tighten the mounting bracket screws evenly until
meter is snug to the panel along its short side. DO NOT OVER TIGHTEN,
as the rear of the panel may be damaged.

Signal Connections
Signal connections are made to a six-terminal connector labeled
SIGNAL on Figure 7. The COM (common) terminal is the return for the
4-20 mA and the ±10 V input signals.
Current and Voltage Connections
The following figures show examples of current and voltage connections.
There are no switches or jumpers to set up for current and voltage inputs.
Setup and programming is performed through the front panel buttons.
Figure 9. Transmitters Powered by Internal Supply
Figure 10. Transmitter Powered by Ext. Supply or Self-Powered
The current input is protected against current overload by a resettable
fuse. The display may or may not show a fault condition depending on
the nature of the overload.
The fuse limits the current to a safe level when it detects a fault
condition, and automatically resets itself when the fault condition is
removed.

The meter is capable of accepting any voltage from -10 VDC to +10 VDC.
Modbus RTU Serial Communications
Serial communications connection is made to an RJ45 connector
labeled M-LINK on Figure 7. For interfacing to the meter, use the
350PDA1232 for RS-232, the 350PDA1485 for RS-485, or the
350PDA8008 for USB. The same port is used for interfacing with all
expansion modules (e.g. external relays, digital I/O).
Relay Connections
Relay connections are made to two six-terminal connectors labeled
RELAY1 – RELAY4 on Figure 7. Each relay’s C terminal is common
only to the normally open (NO) and normally closed (NC) contacts of the
corresponding relay. The relays’ C terminals should not be confused
with the COM (common) terminal of the INPUT SIGNAL connector.

Switching Inductive Loads
The use of suppressors (snubbers) is strongly recommended when switching
inductive loads to prevent disrupting the microprocessor’s operation. The
suppressors also prolong the life of the relay contacts. Suppression can be
obtained with resistor-capacitor (RC) networks assembled by the user or
purchased as complete assemblies. Refer to the following circuits for RC network
assembly and installation:
Figure 13. AC and DC Loads Protection
Choose R and C as follows:
R: 0.5 to 1 Ω for each volt across the contacts
C: 0.5 to 1 µF for each amp through closed contacts
Notes:
1. Use capacitors rated for 250 VAC.
2. RC networks may affect load release time of solenoid loads. Check to
confirm proper operation.
3. Install the RC network at the meter's relay screw terminals. An RC network
may also be installed across the load. Experiment for best results.
Figure 14. Low Voltage DC Loads Protection
RC Networks Available from Viatran
RC networks are available from Viatran and should be applied to each relay
contact switching an inductive load. Part number: PDX6901.
Note:
Relays are de-rated to 1/14th HP (50 watts) with an inductive load.

F4 Digital Input Connections
A digital input, F4, is standard on the meter. This digital input is
connected with a normally open contact across F4 and COM, or with an
active low signal applied to F4.

External Relays & Digital I/O Connections
The relay and the digital I/O expansion modules 350PDA1004 &
350PDA1044 are connected to the meter using a CAT5 cable provided
with each module. The two RJ45 connectors on the expansion modules
are identical and interchangeable; they are used to connect additional
modules to the system.
Note: The jumper located between the RJ45 connectors of the
350PDA1044 must be removed on the second digital I/O module
in order for the system to recognize it as module #2.
Warning!
Do not connect or disconnect the expansion modules
with the power on!
More detailed instructions are provided with each
optional expansion module.

Interlock Relay Feature
As the name implies, the interlock relay feature reassigns one, or more,
alarm/control relays for use as interlock relay(s). Interlock contact(s) are
wired to digital input(s) and trigger the interlock relay. This feature is
enabled by configuring the relay, and relative digital input(s) (see page
62). In one example, dry interlock contacts are connected in series to
one digital input which will be used to force on (energize) the assigned
interlock power relay when all interlock contacts are closed (safe). The
interlock relay front panel LED flashes when locked out. The interlock
relay would be wired in-series with the load (N/O contact). See below.
