IDEC PF3S-PSA2 Programmable Safety Relay Module

I. Overview

The IDEC PF3S-PSA2 is a high-performance compact industrial pushbutton switch, specifically designed for signal input scenarios in industrial automation control systems. It serves as a key interactive component connecting operators and equipment. Its core function is to realize on-off control of circuits or transmission of status signals through manual operation, adapting to various control needs such as start/stop, emergency stop, and mode switching.

II. Technical Specifications

(I) Electrical Performance Parameters

Rated Specifications:

• The voltage adaptation range covers two specifications: AC 250V and DC 24V, which is compatible with AC and DC control circuits commonly used in industry. It can be directly connected to the system without additional conversion components.

• The rated current reaches 10A, which can directly drive loads such as small solenoid valves and contactor coils without the need for intermediate relay conversion, simplifying the design of control circuits.

Contact Characteristics:

• Adopts a double-contact configuration of normally open/normally closed (1NO/1NC). The contact resistance of a single contact is ≤50mΩ, ensuring low loss and high stability in signal transmission.

• The contact bounce time is<5ms, effectively avoiding high-frequency false triggers and adapting to high-response automated control scenarios.

(II) Physical and Environmental Parameters

Appearance and Installation:

• Features a compact design. The standard panel mounting hole diameter is 22mm (an industrial standard size), which is compatible with the mounting hole specifications of most equipment control panels.

• The installation depth only requires less than 30mm, allowing flexible arrangement even in compact control cabinets or equipment panels, thus saving installation space.

Environmental Adaptability:

• Achieves an IP65 protection rating, providing complete dustproof performance and resistance to low-pressure water jets. It can be directly used in humid and dusty environments such as outdoor control cabinets and food processing workshops.

• The operating temperature range is -25℃ to +70℃, which can meet the extreme temperature requirements of outdoor equipment in frigid zones and high-temperature production workshops without additional temperature control measures.

Mechanical Performance:

• The operating life exceeds one million cycles. Calculated based on 100 operations per day, the theoretical service life can reach more than 27 years, significantly reducing the frequency of equipment maintenance.

• The operating force only requires 1.5-3N, allowing operators to press easily. At the same time, it has clear tactile feedback (with a stroke of 2.5mm) to avoid misoperation.

(III) Compatibility Parameters

Anti-interference and Protection:

• Possesses ESD protection capability of ±15kV air discharge and ±8kV contact discharge, complying with the IEC 61000-4-2 standard. It can still transmit signals stably in strong electromagnetic environments.

• The vibration resistance performance reaches 10-500Hz with an acceleration of 5g, which can be adapted to vibrating working conditions such as heavy machine tools and metallurgical equipment.
