Series 115 Motogard™
The Series 115 Motogard is designed to take in up
to 6 Thermistors wired in Parallel, and has two Triac
output relays.
Connections
Power Connections:
The standard 115 Series Motogard relay is designed
to operate off of 120VAC +/-10%, Single Phase,
50/60Hz, and is sold under part number 115101-
2. There is a special 230VAC input power version
available and sold under part number 115202-2.
On terminals 1 & 2 connect incoming AC
power.
Thermistor Connections:
1. Connect one lead of each Thermistor
to terminals 6, 7, 8, 9, 10, and 11
respectively.
2. Connect other leads of each Thermistor
to Common, terminal 5.
3. Maximum number of Thermistors in
parallel: Six (6)
4. Note: If using less than 6 Thermistors.
Any unused input – Install a 150 Ohm
1/2W resistor from sensor common
(terminal 5) to any unused input.
Output Load Connections:
1. With power applied to the controller
and all input sensors in their low
impedance states. Terminal 3 and 4
become the equivalent to a closed
contact of an electromechanical
relay.
2. With power applied to the controller
and all input sensors in their low
impedance states. Terminal 3' and
4' become the equivalent to a open
contact of an electromechanical
relay.

3. Be sure power is never applied directly across
the contact but always in series with the load.
4. Maximum
allowable
120/240VAC.
5. The closed output of the Motogard Over
temperature
Protection
specifically designed to operate directly in
series with most main line contactors. If a small
interposing relay must be used, the sealed
burden shall be greater than 10VA.
6. The open output of the Series 115 relay can be
used for trip indication.
