M-7055D-G

  • Source-type Digital Output with Overload Protection
  • Digital Input Channels Can be Used as 16-bit Counters
  • Short Circuit Protection
  • Configurable Power-on Value and Safe Value Settings

Introduction

The M-7055/M-7055D offers 8 isolated channels for digital input and 8 isolated channels for digital output. Either sink- or source-type inputs can be selected via wire connections. All digital input channels are also able to be used as 16-bit counters. The M-7055(D) supports source-type output with short circuit protection. The M-7055D has 16 LED indicators for channel status monitoring. The M-7055(D) supports Modbus RTU and DCON protocols, which can be configured via software. There are also options for configuring power-on and safe values. 4 kV ESD protection and 3750 VDC intra-module isolation are standard, and all hardware specifications are the same as the I-7055(D).
