Allen-Bradley 700-HLS1Z24 Terminal Block Relay Module

Configured for DC load switching in Allen-Bradley control systems, the Allen-Bradley 700-HLS1Z24 (700-HLS1Z24 Terminal Block Relay Module) provides direct solid-state switching of field loads through a compact DIN-rail-mounted interface. The module combines relay functionality, terminal block wiring, LED status indication, and polarity protection within a narrow-width housing intended for high-density control cabinet installations.

Hardware Specifications

Profinet and Control Cabinet I/O Density Optimization

The 700-HLS1Z24 is designed for applications requiring compact switching interfaces between PLC outputs and field devices. Its 6.2 mm housing width allows increased I/O density within control panels where cabinet space is limited.

The solid-state switching architecture eliminates mechanical contact wear associated with electromechanical relays. Integration with Allen-Bradley PLC platforms and other industrial controllers enables fast switching of DC field loads while maintaining electrical separation between control and load circuits.

The integrated LED indicator provides direct visual confirmation of switching status, simplifying commissioning and troubleshooting activities in distributed control installations.

Frequently Asked Questions

Q: Does the 700-HLS1Z24 use mechanical relay contacts?
A: No. The module utilizes a solid-state MOSFET/transistor output and does not contain mechanical switching contacts.

Q: What is the maximum rated load current?
A: The module is rated for 2 A resistive loads at the specified output voltage conditions.

Q: Is reverse polarity protection included on the control input?
A: Yes. The control circuit incorporates reverse polarity protection along with an integrated LED status indicator.

Field Installation Guidelines

• Mount the module on a properly grounded 35 mm DIN rail.

• Verify control voltage remains within the specified 19.2 to 30 VDC operating range.

• Observe correct polarity when wiring the 24 VDC control input.

• Tighten screw terminals according to site electrical standards.

• Route load wiring separately from low-level signal circuits where practical.

• Confirm the connected load does not exceed the 2 A output rating.

• Maintain adequate spacing and ventilation within high-density control panels.

• Verify LED status indication during commissioning and maintenance procedures.
