PAM Series Multi Voltage Control Relays
Owner’s Manual
Description
The PAM Series Relays are encapsulated multivoltine devices with “flying” leads
that offer versatile, reliable performance in a convenient package. Several of
the versions contain a red LED which indicates when the relay coil is
energized. The PAM Series Relays are packaged with a self-tapping screw and a
piece of double sided tape for easy installation almost anywhere. The relays
are also packaged with wisents to aid installation.
PAM Relays are ideal for applications where remote relays are required for
control or status feedback. They are suitable for use with HVAC, Temperature
Control, Fire Alarm, Security, Energy Management, Lighting Control Systems
and Building Automation Systems.
PAM-1
The PAM-1 Relay provides 10.0 A form “C” contacts. The relay may be energized
by one of three input voltages: 24VDC, 24VAC, or 120VAC. The input voltages
are polarity-sensitive and diode-protected. PAM-1 Relays contain a red LED
which indicates when the relay coil is energized. This relay may not be
suitable for continuous duty use at 120VAC for extended periods of time. For
these applications, please refer to our RIC-Series products.
Features
- Multi-voltage operation
- Activation LEDS to indicate when the relay coil is energized
- Easy installation
- Ideal for applications where remote relays are required for control or status feedback
- Suitable for use with HVAC, Temperature Control, Fire Alarm, Security, Energy Management, Lighting Control Systems and Building Automation Systems
PAM-2
The PAM-2 Relay provides 7.0 A form “C” contacts. The relay may be energized
by one of two input voltages: 12VDC or 24VDC. The input voltages are polarity-
sensitive and diode-protected. PAM-2 Relays contain a red LED which indicates
when the relay coil is energized.
PAM-3
The PAM-3 Relay provides a 3.0 A form “A” contact. The relay may be energized
across a wide voltage range from 9VDC to 40VDC, making it ideal for 12VDC and
24VDC EOL circuits. The 19.3 mA operating current is constant across the
operating range. The input voltage is polarity-sensitive and diode-protected.
PAM-4
The PAM-4 Relay provides 10.0 A form “C” contacts. The relay may be energized
across a wide voltage range from 9VDC to 40VDC, making it ideal for 12VDC and
24VDC EOL circuits. The 15mA operating current is constant across the
operating
