CruzPro ER-1 External Relay

The ER-1 External Relay switch can be connected to the
inchexternal alarminch output of many of the CruzPro instruments
and used to switch high current loads with the normally open and
normally closed relay contacts.

The input resistance of the control line is 10,000 ohms minimum
and a Control voltage of between +3.5 to +12 VDC can be used to
switch the relay from OFF to ON.

The external relay switch is powered by 12 or 24VDC and
typically draws only 0.035 amps when the relay is switched ON and
almost no power when the relay is switched OFF.

Specifications:

• Supply Voltage: 10.0 to 30.0 VDC 0.035 amps max.
• Relay Contacts: 10 Amps maximum. Both NO (Normally Open) and NC
  (Normally Closed) contacts.
• Operating temperature: 0 to 50 deg Celsius ( 32 to 122 deg
  Fahrenheit).
• Size: 50 x 35 x 30 mm (2 x 1.4 x 1.2 inch)
• Control: Low power +3.5 to +12 VDC switches the relay ON.
• Input Resistance (Control Line): 10K Ohms minimum.
