Item Code: ER-1 The ER1 is an external relay switch with both normally open and normally closed relay contacts that can be activated by the "external alarm output" available on many CruzPro instruments. The ER1 can be powered by any voltage between 10 and 30 VDC and draws only 0.035 amps when active and almost no current when OFF. The relay is activated by a +3.5 to +12VDC control signal.
The ER-1 External Relay switch can be connected to the "external alarm" 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.
