Key Features
6 A SPDT Changeover Output
Its single changeover contact provides common, normally open and normally closed switching paths. The 6 A nominal contact rating supports properly specified industrial control loads, subject to the applicable resistive and inductive switching limits.
Integrated LED Status Indication
The relay assembly includes an LED indicator to help maintenance personnel identify relay energization and diagnose control signals during equipment installation and servicing.
Touch-Safe Screw Terminal Base
Touch-safe screw terminals support secure field wiring, while the integrated relay socket allows the relay element to be serviced or replaced according to the manufacturer's installation procedure.
Compact Interposing Relay Design
The 700-HL family is intended for high-density interface and isolation applications, making this model suitable for PLC output interfacing and industrial control cabinet wiring.
Integrated DC Circuit Protection
The 700-HL series includes DC reverse-polarity and coil surge protection features. These functions support correctly wired control circuits but do not replace external overcurrent protection or safe system design.
Applications
- PLC output interface and interposing relay circuits
- Industrial control panel signal switching
- Machine automation control systems
- Electrical isolation between control circuits
- Industrial alarm and indication circuits
- Factory equipment relay maintenance
- Control cabinet terminal block relay assemblies
- Replacement of matching Allen-Bradley 700-HL relays

Frequently Asked Questions
What is the Allen-Bradley CAT700-HLT1Z24?
It is a 24 VDC electromechanical terminal block relay in the Allen-Bradley 700-HL series, featuring one SPDT changeover contact, a 6 A nominal current rating, screw terminals and an LED status indicator.
Is CAT700-HLT1Z24 the same as 700-HLT1Z24?
CAT is commonly used to mean catalog number. Rockwell Automation lists the official product identifier as 700-HLT1Z24. Confirm the label on the offered product.
What is the relay coil voltage?
The relay operates from a nominal 24 VDC control supply. Use the manufacturer's specified supply tolerances and wiring requirements.
What contact configuration does it have?
The 700-HLT1Z24 has one SPDT changeover contact, also known as one Form C contact or one C/O contact.
What is the nominal contact current?
Rockwell Automation specifies a nominal contact current of 6 A. The permissible load depends on the switching voltage, load type and electrical life requirements.
Does the relay include a socket?
Yes. Rockwell Automation identifies 700-HLT1Z24 as complete with a socket and screw terminal connections.
Does it have an LED indicator?
Yes. An integrated LED provides a visual indication associated with relay operation.
Is the output solid-state or electromechanical?
It is an electromechanical relay with a mechanical SPDT contact, not a solid-state relay. Other products in the 700-HL series offer solid-state outputs.
What is the enclosure protection rating?
The manufacturer specifies IP20. The relay is intended for suitable protected electrical installations rather than direct exposure to liquids or heavy dust.
What is the recommended terminal tightening torque?
The 700-HL series technical data specifies a maximum recommended screw terminal tightening torque of 0.5 N·m.
Can it be used as a safety relay?
The 700-HLT1Z24 is a general-purpose electromechanical terminal block relay and does not have force-guided contacts. It should not be substituted for a certified safety relay in a safety-related control function without an appropriate safety assessment.
What should be checked before ordering?
Confirm the official catalog number 700-HLT1Z24, 24 VDC coil voltage, 6 A nominal contact rating, SPDT configuration, screw terminal connection, included relay socket, IP20 protection, contact load requirements, installation compatibility and actual seller quantity. If hazardous-location certification is required, verify the appropriate catalog variant and approvals.
