The MAX22199 is an IEC 61131-2 compliant industrial digital input device. The MAX22199 translates eight 24V current-sinking industrial inputs to a serialized SPI-compatible output that interfaces with 3V to 5.5V logic. It can operate as eight Type 1/Type 3 digital inputs or four Type 2 digital inputs. The device provides diagnostic functions, including thermal shutdown, 24V under voltage alarm, 24V missing voltage alarm, and SPI and CRC communication error detection. All of the faults can be configured to generate an interrupt using the active-low FAULT pin.

For robust operation in industrial environments, each input includes a programmable glitch filter. Noise filters on each channel can be independently programmed to one of eight values between 50µs and 20ms or filter bypass.

The MAX22199 has a 4-pin SPI interface and, in addition, uses the active-low LATCH input for synchronizing input data sampling across multiple devices.

The MAX22199 field-side accepts a single 7V to 65V supply to the VDD24 pin. When powered by the field supply, the MAX22199 generates a 3.3V output from an integrated LDO regulator, which can provide up to 25mA of current for external loads in addition to powering the MAX22199. Alternatively, the MAX22199 can be powered from a 3.0V to 5.5V logic side supply connected to the VDD pin. For flexibility, the SPI interface operates at 3.3V or 5V logic levels as controlled by the VL pin.

Product Detail

The MAX22199 evaluation kit (EV kit) provides the hardware and software necessary to evaluate the MAX22199 Octal Industrial Digital Input device. The MAX22199 EV kit receives commands from a PC through the USB port to create a SPI interface for communication between the software and the MAX22199 on the EV kit. The MAX22199 EV kit also has a Pmod™ compatible connector for SPI communication with an external host device such as a MCU or FPGA.

The EV kit includes a graphical user interface (GUI) that provides communication between the target device and the PC. The MAX22199 EV kit has a MAX22199 device that supports Type 1, 3 inputs with the current sink limit set by an on-board resistor. The MAX22199 EV kit is designed to support transient immunity testing for ESD, EFT, and Surge according to IEC 61000-4-2, IEC 61000- 61000-4-4, and IEC 61000-4-5 respectively. The EV kit can operate in multiple modes, as shown in the System Block Diagram:

1) USB Mode: If SW1 are all closed, the MAX22199 SPI receives commands through the USB port from the Maxim-supplied EV kit software.

2) Pmod Mode: If SW1 are all open, the MAX22199 SPI receives commands through the PMOD1 connector. This industry standard connector connects to popular MCU or FPGA platforms. The user is required to generate firmware to provide the SPI commands.

Applications

  • Building Automation
  • Distributed Control System
  • Motor Control
  • Programmable Logic Controllers
