Part Details for MAX12 by MEC Switches A/S

The MAXREFDES1165 is a complete, 32-channel industrial digital I/O module comprising 16 digital inputs (DIs) and 16 digital outputs (DOs) that is built and tested in an industrial form factor to meet transient immunity standards such as IEC 61000-4.<p>The MAXREFDES1165 is a proven design that provides the hardware and software necessary to demonstrate the MAX22190 octal industrial digital input device with diagnostic features, and the MAX14915 octal industrial digital output with high-side switches. In this reference design, two MAX22190s are configured in daisy-chain mode, and two MAX14915s are configured in addressable SPI mode. Galvanic isolation is provided by the MAX14483 and MAX12930 to isolate the data from the logic (SPI master) and field (24V) sides.<p>The MAXREFDES1165 has a 12-pin Pmod™-compatible connector (CNT1) for external SPI communication. For testing purposes, the reference design uses Maxim’s USB2PMB2# adapter board that receives commands from a PC through the USB port and translates them into an SPI interface. Alternatively, the user can connect the reference design board to any Pmod-compatible board, such as an FPGA or microcontroller system, and write their own software for controlling the MAX22190 and MAX14915.<p>Other features include the following:32 Digital I/Os: 16 Inputs and 16 Outputs<p>High Integration Reduces BOM Count and PCB Space<p>Fault Tolerant with Built-In Diagnostics<p>Robust Design to Meet IEC 61000-4

Overview<p>The MAXREFDES176# is a complete, IO-Link® 16-channel digital input hub reference design that consists of a MAX22515 IO-Link transceiver with integrated protection. It demonstrates an isolated digital input hub using the MAX22192 isolated octal digital input device daisy-chained with the MAX22190 octal digital input device to provide a total of 16 digital input channels.<p>Type 1 and Type 3 sensors are supported by default. Type 2 sensors can also be supported by modifying the resistor value that controls the value of the current sink within the devices. Built in an industrial form factor, the MAXREFDES176# uses an industry-standard M12 connector, allowing a 4-wire cable to be used. The digital input channels use industry-standard PCB terminal blocks.<p>In this design, an Atmel® ATSAM low-power microcontroller interfaces between the MAX22192 isolated digital input serializer and the MAX22515 IO-Link device transceiver. The MAX22515 features integrated surge protection for robust communication in a very small PCB area without requiring external protection components, such as TVS diodes. The MAX22515 is available in a tiny 20-bump WLP package, allowing the MAXREFDES176# to have a small footprint, though this is mostly determined by the size of the connectors. The design is reverse-polarity protected using the integrated active reverse-polarity protection of the MAX22515. The MAX22515 has two integrated LDO regulators (3.3V and 5.0V). The 3.3V LDO is used to generate the 3.3V supply for other circuitry, reducing the number of required external components and further saving space. The MAX22515 also features low on-resistance drivers (C/Q and DO/DI) to reduce power dissipation, allowing this reference design to consume minimal power with very low thermal dissipation.<p>This IO-Link device utilizes the Technologie Management Gruppe Technologie und Engineering (TMG TE) IO-Link device stack to communicate to any IO-Link version 1.1-compliant master. The board contains a male M12 connector for connecting to a compliant IO-Link master using a standard M12 cable. Connecting the MAXREFDES176# to a USB IO-link master, such as the MAXREFDES165#, with the associated software allows for easy evaluation.<p>Design files, firmware, and software are available on the Design Resources tab. The board is also available for purchase.

The MAXREFDES145# is a fully IO-Link®-compliant, 8-port IO-Link master reference design. This design uses TEConcept's IO-Link master stack and is both an IO-Link master reference design as well as an IO-Link sensor/actuator development and test system. Eight IO-Link ports allow for simultaneous testing of up to eight different sensors (or actuators). The reference design has eight robust female M12 connectors, the most common connector used for IO-Link, and ships with two IO-Link cables to quickly connect to IO-Link compatible sensors and actuators. An AC-to-DC (24VDC/1A) power-supply cube is capable of providing at least 125mA simultaneously to each port and more when fewer ports are unused. A USB 2.0 Type B connector allows for quick connectivity to a Windows® PC.<p>The easy-to-use TEConcept Control Tool (CT) GUI software with IODD file import capability makes the MAXREFDES145# a must-have for any company or engineer serious about developing IO-Link products.
