Solid-state discrete output relays (1A DC loads), 0 to 48V DC
Frequency/Pulse Counter Modbus-RTU Input Moduleswith Periodic or Pulse Waveform Input This signal conditioner is a two-channel analog input module with discrete outputs and Modbus communication. It conditions periodic or pulse waveform inputs and provides solid-state relays for limit alarms or ON/OFF control. Versatile inputs accommodate many applications using TTL, magnetic pickups, proximity sensors, or a variety of switches (high/low-side transistor, dry contact, open drain, open collector). Inputs may also function as event counters with separate microcontrollers for each channel. The module counts pulses on the positive or negative edge. The discrete outputs can operate as independent alarms or provide on/off control regulated by the host system. As limit alarms, each output can be set for high and/or low setpoints exclusively tied to an analog input.Modbus RTU Frequency/Pulse Counter input module: 2 input channels

Why choose IPC Station?

chervon down
IPC Station' parent company, GID Industrial, specializes in procuring industrial parts. We have years of experience finding rare and obsolete equipment that our customers need in order to get back to business. There are other companies who claim to do what we do, but we're confident that our commitment to quality and value is unparalleled in our field.

What is IPC Station' warranty policy for the 942MB-0900?

chervon down
The warranty we offer will be based on what we negotiate with our suppliers. It is possible for some parts to be sold as-is and without a warranty. Our specialty, single board computers, tend to receive a one-year warranty.

What carriers does IPC Station use to ship parts?

chervon down
We use FedEx, UPS, DHL, and USPS. We have our own accounts, but we can also use yours if you would prefer. However, we can use other carriers if it will be more convenient for you.

What they say about us


star star star star star

One of our top priorities is maintaining our business with precision, and we are constantly looking for affiliates that can help us achieve our goal. With the aid of GID Industrial, our obsolete product management has never been more efficient. They have been a great resource to our company, and have quickly become a go-to supplier on our list!

Bucher Emhart Glass


star star star star star

With our strict fundamentals and high expectations, we were surprised when we came across GID Industrial and their competitive pricing. When we approached them with our issue, they were incredibly confident in being able to provide us with a seamless solution at the best price for us. GID Industrial quickly understood our needs and provided us with excellent service, as well as fully tested product to ensure what we received would be the right fit for our company.



star star star star star

Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.

Applied Materials


star star star star star

Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

Trican Well Service


star star star star star

When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
