81545-01 GE Relay Card

Review GE Relay Card

The GE 81545-01 Relay Card, type T238382, is a versatile and reliable solution for controlling electrical circuits in various applications. This particular model is designed to fit into GE Central handler CH series Controls and is specifically designed for use with the T238 and T239 (low voltage containers). At a glance, this relay card features 20 Form C controllable SPDT (Single Pole Double Throw) relays, each capable of handling up to 1 ampere and 30 volts DC, making it suitable for a wide range of control requirements.

Each relay is mechanically actuated and electrically isolated from the power circuit, ensuring safe and efficient operation. With this card, there is no need to worry about potential electrical interference or shorts, as the relays are well-protected by the card's robust construction. It also includes diodes to prevent inductive kickback from coils that may damage the card.

Installation of the GE 81545-01 Relay Card is straightforward with convenient mounting provisions for securing it into the control panel using screws. It's essential to note that a received de-energized (open circuit) input signal is necessary for the relay to switch on, and when the input signal is removed, the relay will return to its initial state. This feature, combined with the card's reliable performance, makes it a strong choice for applications that require smooth circuit control.

The GE 81545-01 Relay Card, type T238382, is not only dependable but also flexible in various applications. It offers numerous benefits such as efficient use of MTUs (Modular Terminal Units), easy replacement and maintenance, as well as compatibility with select GE control panels by utilizing replaceable terminal blocks. Overall, this card is designed to meet the rigorous demands of industrial automation needs and provide a long-lasting solution for your control challenges.

Pros and Cons of buying a GE 81545-01 Relay Card T238382

The GE 81545-01 Relay Card T238382 is a UL Listed, NEMA rated and RoHS compliant 8-channel solid state relay module. This device is commonly used for various automation applications. Let's discuss some advantages and disadvantages of investing in the GE 81545-01 Relay Card to help you make an informed decision.

1. Solid State Technology: This relay card uses solid-state technology which offers high reliability, long life and requires no maintenance. Solid-state relays (SSR) do not have electrical contacts like traditional relays, which can deteriorate over time or malfunction due to wear, resulting in fewer failures and reduced downtime.

2. Smaller Size: The sleek form factor of the GE 81545-01 Relay Card facilitates easy installation in space-constrained applications. Its compact design makes it an ideal solution for makers, DIY projects, and industrial control systems where space is at a premium.

3. Wide Operating Temperature Range: The GE 81545-01 Relay Card has a wide operating temperature range of -40 to 115 C (-40 to 239 F) which makes it suitable for harsh environments in various industries like automotive, oil & gas, and HVAC.

4. Isolation Voltage: The card provides a high level of isolation between the digital control input and the output contacts - a factor that makes it a safer choice for applications where high-voltage systems are involved.

5. Remote Turn-Off Capability: This relay card supports remote turn-off capability which can be particularly advantageous in applications that require precise control over AC loads while securing operator safety.

1. Limited Current Capacity: With a maximum contact rating of 10A and a low voltage drop, the 81545-01 might not be the best choice for handling heavy loads or high power applications. In such cases, higher capacity relay cards should be considered to ensure proper functionality and system reliability.

2. Limited Operating Frequency: The GE 81545-01 Relay Card operates at a relatively low switching frequency, making it unsuitable for fast switching applications. However, this should not pose a problem in the majority of applications where rapid switching is not a prerequisite.

3. Limited Input Sources: This relay card has a limited set of acceptable input sources: 3-15V DC or AC. It may not be compatible with other input voltage standards, so ensure your intended application conforms to the listed specifications.

The GE 81545-01 Relay Card presents numerous advantages for various automation applications that require compact, reliable, and safe solutions. While it comes with limited constraints concerning its maximum load capacity, switching frequency and input sources, the benefits offered such as a wide operating temperature range, remote turn-off capability, solid-state technology, and small form factor often outweigh its drawbacks.

For applications where a compact, reliable and efficient 8-channel relay card with high isolation voltage is needed, the GE 81545-01 Relay Card T238382 is a solid choice. It can be utilized for controlling various industrial systems, DIY projects, and automation applications that do not require handling large or heavy loads or quick switching capabilities.
