Key Features
- 10 Isolated Inputs
- Small size -- 4 3/4" w X 5" l X 1" h (1 3/4" h
with incandescent lamp driver board)
- Low cost
- Easy to expand number of inputs which only require 3 wires to connect
additional 10 input "Slave" boards
Back to Top
- Burner systems, Printing Presses, HVAC systems, Conveyers....
- Any electrical circuit with a number of contacts required for a
permissive run.

Eliminates "guesswork" of which device contact opened
first to trigger shut down of the equipment, which ultimately allows LESS DOWNTIME.
Back to Top
- 10 isolated inputs with LED display
- 90 - 250 V AC or DC (other voltage Ranges available)
- on board reset, remote reset may also be used
- on board lamp test
- "Piggyback" board available for remote incandescent lamps
- LED indicator lamps may be remote via 14 pin DIP connector and cable

Bench Test the Unit
Use Caution During This Section! You will
be using live 120 VAC!
- Connect 120 VAC to "L" and "N"
terminals.
- Green RST LED (RESET) should be on.
- Push and hold PBT red push button (TEST).
- All red LED's 1 - (1) 0 will light and the green LED
will go out.
- Push PBR green push button (RESET).
- All red LED's will go out and the green LED will come
on.
- Using a custom made test cord, (see Figure 1) touch
input #1. (The 2.2K ohm resistors prevent sparks and breaker tripping if the test cord
ends touch.)
- LED #1 will light up and the green LED will go out.
(NOTE: Touching any other input will not make that LED light up. Once an input is tripped
it is locked on it until it is reset.)
- Repeat the previous steps until all ten inputs are
tested.
Figure 1
Remote Reset
- Remove jumper at "XX" terminals.
- Connect N.C. low power switch or relay contact at
"XX" terminals.
- Note: When a remote reset switch is connected to the
terminals "XX" the circuit board reset switch will still function as normal.

False Tripping
- False Tripping can be caused by Noise.
- This section will explain how to stop Noise from
causing false indications.
- Noise is sometimes generated by the relay or the
starter in a monitored circuit.
- Noise my be suppressed by placing a .01 or .02 mfd
capacitor across the coil of a small or large "Ice Cube" relay.
- Be sure to use a 250 V capacitor when used on a 120
VAC coil.
- For small to medium starters use .1 mfd in series with
a 100 ohm 1W resistor.
- For an example see figure 2.
Figure 2
14 Pin DIP Connector
- This section will explain the DIP connector cable
wiring for remote LED's.
- Note: LED's must be used.
- Pin 13 is a Normally Open contact that closes to 0V on
a fault condition.
- Contact 13 may be used to signal a customer's computer
logic.
- Wire # 14 is red.
Wire #'s 1 through 10 are LED's 1 through 10
Wire # 11 = RESET
Wire # 12 = V+
Wire # 13 = Normally Open Contact (closes to 0V on a fault condition)
Wire # 14 = 0V or Ground "RED WIRE"
