Engineers can rely on this new line of control relays for dry or latching contacts, polarity reversal, phone line seizure, and other switched control logistics. They can also aid in the customization of security systems. The HRB5 and the HRB1224 control relays feature a set of DPDT contacts, which are rated 5 A/120 VAC/28 VDC. The HRB5 model offers 6/12 VDC selectable operation with a 120 mA coil draw, while the HRB1224 features 12/24 VDC selectable operation and a 50 mA coil draw. The HRB610 is a 6-unit relay cluster that can be used as a complete unit or snapped apart for individual use. This device is a 12/24 VDC selectable 50mA coil draw control relay with SPDT contacts, which are rated 10 A/120 VAC/28 VDC. All models feature LED indication of relay operation for diagnostic purposes. The control relays can be mounted via foam tape, which is standard, or with the optional HST34 snap track. Screw terminals accommodate up to a 12-gage wire.
