| Madison
Company offers a wide variety of relays and controllers
for use with our level and conductivity switches and
sensors. Relays
are used for switch overload protection and for solenoid
valve, pump and alarm applications. Controllers are used
in pump-up or pump-down applications. |

| Relays |
• |
R1
General-Purpose Relays provide
liquid level switch overload protection
for all Madison single-level
switches. Input coils are available for 110
VAC, 220 VAC or 12 VDC applications. The isolated
output contacts can be used to switch
a wide variety of voltages. The relay can be
used for solenoid valves, pumps and
alarm applications that do
not exceed the listed ratings. |

| Controllers |
| • |
EZM & ESM Series Process Controllers, Indicators & Time/Counters mate to any of our liquid level switches, ultrasonic sensors, thermocouples or RTD temperature sensors. This common family of interfacing devices offers both a base unit and modular chip that is inserted to provide flexibility when input signals vary from one sensor to another, plus a common base type. This is the most cost-effective way to maintain a factory-wide system or multiple application needs. |
| • |
R2-120
and R2-220 Level Controllers provide
high-level, low-level or bilevel control
in a convenient octal plug-in package.
Models are available for pump-up or
pump-down operation.Onboard sensitivity-adjustable
units eliminate false tripping caused
by floating debris and foaming agents.
Isolated electromechanical relay contacts
can be directly connected to the control
circuitry or control pumps and solenoids. |

| Displays |
• |
ED
Series Loop Powered Displays indicate
the percentage full or empty in
tanks whose level is being monitored
by a sensor with a 4-20 mA output.
Both probe-mount and wall-mount
units are available. |
|
| PD
Series Meters, Controllers & Annunciators |
• |
Model
PD765 Trident Meter is
a universal panel meter for all common
process display applications. Meter
is factory calibrated to accept process
voltage and current inputs, 100 ohm
platinum RTDs and the four most common
thermocouples. |
• |
Loop
Powered Meters are available
in NEMA 4X and explosion-proof models,
with a loop powered backlighting
option. |
• |
ConsoliDator® Multi-Channel
Controllers are wall-
or panel-moutable controllers with
easy-to-read LCD screens, featuring
various combinations of analog, pulse
and digital inputs, analog outputs
and relays. |
• |
Model
PD141AFO Vigilante® Annunciators handles
all types of operational messages,
from urgent alarms to routine announcements,
with simplicity and economy. |
