Allen-Bradley H100-702 Pressure Switch

Product Description

Configured for pressure monitoring and switch-state control in industrial control circuits, the Allen-Bradley H100-702 (H100-702 Pressure Switch) provides direct mechanical-to-electrical switching through an SPDT contact mechanism. Pressure applied to the sensing element changes the internal switch state at the configured setpoint, while the tamper-resistant setpoint lock restricts unintended adjustment.

Hardware Specifications

Industrial Control Circuit Integration

The Allen-Bradley H100-702 operates as a discrete pressure-actuated control device rather than a networked I/O module. Therefore, EtherNet/IP, backplane bus communication, deterministic network timing, and firmware flash compatibility are not applicable to the pressure sensing and switching mechanism.

Instead, the device converts a mechanical pressure condition into an electrical SPDT contact transition. The contact circuit can then interface with compatible industrial control, alarm, interlock, or motor control circuits. Correct conductor routing and electrical isolation from high-noise power circuits help prevent unwanted switching or interference at connected control inputs.

Frequently Asked Questions

Q: What type of electrical contact does the H100-702 use?
A: The H100-702 uses an SPDT contact arrangement, providing one common connection with two switched contact paths.

Q: What pressure connection is provided?
A: The pressure switch uses a 1/4 in NPT female process connection. The mating process fitting should be compatible with the application pressure and installation requirements.

Q: Does the H100-702 require a firmware configuration or industrial communication network?
A: No firmware or network configuration is specified. The device performs direct pressure-actuated mechanical switching through its electrical contacts.

Field Installation Guidelines

Install the pressure switch using a compatible 1/4 in NPT process connection and suitable sealing practices for the application. Do not apply installation torque directly to the switch housing unless permitted by the applicable mechanical installation procedure.

Route pressure lines to prevent excessive vibration, mechanical stress, or contamination from reaching the sensing connection. Keep electrical wiring separated from high-power conductors where practical.

Before energizing the connected circuit, verify the pressure range, maximum pressure limit, electrical rating, and required switching function. The setpoint lock should remain secured after adjustment to prevent unauthorized changes. Disconnect electrical power before servicing field wiring or switch terminals.
